Main two items of dislike would be:
- I expected some kind of alarm feature, both hourly and daily or 2 alarms. No alarms!!!
- The Iphone items are overrated!! phone disconnects often, and its not worth the feature if you are targeting it for that.

Additionally the day of the week indicator doesn't work except to program the watch initially. Its not as important as the other two features, but would be nice to see if its Wednesday or Friday if you have a busy week on the go and forget.

Beautiful face, elegant and comfortable strap even for a guy with a big wrist.

Probably wouldn't do it again if I had the choice...

Citizen watches are always a great watch and this one will not disappoint. It works OK as a standalone watch but is quite complicated to setup. However once you connect it to your iPhone it is easy to use and maintain. Overall it is a very good watch and is recommended to all IPhone users, sorry Android and Blackberry users this one is not for you at this time.

Love the watch. The solar charging works life a charm. The blue tooth connection is a bit finicky with my iPhone so that's why only 4 stars not 5. Would I recommend, absolutely.

HASH(0xa7a763b4) out of 5 stars Great Looking Watch - Terrible Functionality Dec 8 2012
By T. Scott - Published on
First, let me preface this review by stating I've been in the IT industry for 16+ years.. I'm a total geek and have tons of gadgets (AKA I know what I'm doing)..

I was super pumped for this watch because of the geek factor. I have an iPhone5 with an Otterbox w/ beltclip so often times I don't hear / feel my phone ring.. Perfect solution, right?!?!

I think it would have been, had it worked.. For one thing.. When you get an "alert" (ie: Phone call, email, calendar appt) it is two very quick and very light vibrations on the watch.. So light you barely feel them.. Now, this wouldn't be a big deal if vibrated constantly until you acknowledge (ie: answer the phone or whatever) but it doesn't..

Then, it loses connectivity CONSTANTLY.. My watch and phone will literally both be on my body and it will STILL lose connectivity.. The repairing is supposed to be simple (hold the upper button for about 2 seconds) but it very rarely works.. I have to close the app, reopen, kill the app, open, turn off bluetooth, turn it back on, etc.. Only for it to get disconnected again an hour or so later.. FRUSTRATING!!

Then, it only works with IMAP email.. So, my Exchange accounts go out the window..

The pros are the simple fact that the watch looks amazing.. I love the looks and the feel and weight.. Very solid..

*Time syncs with iPhone (so basically atomic)
*Perpetual calendar
*LOOKS! :)

*Vibrations are so quick and light you barely feel
*Vibrations are two quick and short ones then done.. Not constant (ie: a phone call)
*No alerting for text messages
*CONSTANT disconnects
*Reconnecting is a nightmare

So yea, I think in a few years we'll see way more watches with functionality but as of now, it's still no go.. :(

HASH(0xa7b7960c) out of 5 stars Finally a nice Blu Tooth watch!! Nov. 25 2012
By ratpackfan - Published on
I've been wanting a Blu Tooth watch to sync with my iPhone 4s for quite some time. Citizen got this one right. Once you figure it all out, it's a breeze to operate. It comes with a USB instruction manual that guides you step by step to get you going. Once you sync your phone to the watch, the time and date is set perfectly. I checked it with atomic clock and it's spot on. If you loose your iphone, simply hold the two pushers down and your iphone will chime until you open the Citizen app. The watch will remain synced with the iPhone for 6 hours and it auto disconnects. It does this to save battery power for both the iPhone and watch. The watch does feature the Eco-Drive, so some may wonder why you would be concerned about the battery life. In the instruction it breaks down the life when using the Blu Tooth and when it's off. There is a considerable difference. Once it disconnects it's vey simple to re-connect. Simply hold the upper right pusher down for 2 seconds. It then reconnects and sets the time.

I've had the watch less than 24 hours so here are my initial ratings. With a scale of 1-10 and 10 being the highest.

Fit & Finish-8-The strap is OK. Retro looking, but average quality.
Weight -9-Very light weight.
Ease of use-7-Only a techie will fully understand and use all the features.
Crystal -6-Mineral with AR coating. I feel that at this price point they should offer Sapphire.
Features -9-I would give it a 10, but the Email feature doesn't work with the icloud. Perhaps in an update they will fix this.
Size- -7-For some the size may be just right. But I'm use to larger watches.

I've owned and still own a number of Citizen watches and they have proven very reliable. More reliable than my Seiko watches I've had in my collection. The Eco-Drive is much better than the Kinetic power supply Seiko uses. Seiko has started using Solar power in some of their newer watches. So Citizen must be on the right track.

HASH(0xa869e798) out of 5 stars April 2014 update : Great watch. Dec 19 2012
By J. Talbert - Published on
Update 4/28/14

Call me impressed. Rating went from a 3 originally to a 4, and now to a 5.

Where to start. Back in Sept spoke to Citizen and was told that they had three firmware updates coming for the watch, with the big one in March 2014 which will be a total rewrite of the code and add new features.

I sent my watch in for the first update which helped some but still disconnects. I skipped the Dec update and waited till the March update.

I waited till the middle of march before I thought about contacting Citizen and before I could contact them, I saw they had release v2.5 of the app and firmware. I waited a few weeks to contact Citizen to get he initial wave of updates done. I contacted support, they emailed me a prepaid shipping label and I sent my watch off and got it back today. So here is my update.

I got it back today and the past few hours it has been working flawlessly. The way the watch connects to the phone via bluetooth is through the iOS now and not through the app, so its much better with connections. I have been wearing it for 5 hours and it was not dropped from the watch once. With the old method it would have dropped 3-5 times.

To do the firmware update, you need to ship to Citizen. Because they said they realize you will be without the watch for a while, they are extending the warranty for an additional year for no charge.

I liked this watch before, but did not use the BT feature much due to reliability but now will be much more, especially since it will vibrate on text messages, FB messenger messages and other things. Citizen could have given up on this watch but they have stood behind it and not only have they released incremental updates to try to make it work better but opened it up to a whole new level with the new features.

One other new feature, need to contact Citizen to confirm this is still the case, but with the rewrite of the code. Once you update the app to 2.5 and send it for firmware update. The new App will have the ability to do the firmware update via bluetooth so you will be able to apply any future firmware updates to your watch yourself and not send it in. Will confirm if this is still the case.

But yes LOVE LOVE LOVE this watch!

Update 9/17/13

iOS 7 is released tomorrow and a few VERY Important things
1) The firmware in the watch is not compatible with iOS 7.
2) Will need to send your watch to Citizen for a firmware update.

I spoke to someone in customer service for Citizen the other day. Current turn around time is 2-3 weeks and will only get longer once iOS 7 is out in the open for everyone to install.

Citizen has THREE FIRMWARE updates coming
1) September
2) December
3) March 2014

Sept update is available now. It will only address the iOS 7 compatibility issues
December update will be bug fixes

March will be a TOTAL re-write. Citizen knows about the connectivity issues with the iPhone and the watch, and this total re-write will resolve this issue AND will include new features including notification for SMS text messages and Facebook messages and other notifications as well including added email support types.

What I was told is if you have the watch and send it in now for the Sept update, skip the December update and send in again in the March time frame for the new re-written firmware.

Still love my watch. Even though I dont use the notification feature a lot, it has worked when I needed it to.

Update 1/9/2013

I have had the watch for about a month and bump my review from 3 stars to 4 stars. Maybe even 4.5 :-)

Look 9: I really love the look of this watch, the more I wear it, the more I love it. I have received many compliments regarding this watch.

Feel: 8 Now that I have been wearing the watch for a while I am getting use to the watch and like the band. I question the durability of it. The leather shows odd bends around the clasp. But thats for a later update.

Functionality (Non bluetooth): 9. The watch works great, don't know why I gave this an 8 first time, but it keeps time, it does exactly what I thought it would do and want it to do. The only thing I am surprised about is it does not have an alarm. Not that I would use that feature, but most of the Citizen watches do have alarms. Alarm would be really cool if it would vibrate during the alarm.

Functionality (Bluetooth when paired): 9. I think the vibrate works well, not too hard, not too soft, but Citizen did it in a manner not to kill the battery life. The only thing I wish they would add is Text notifications.

Functionality ( bluetooth) connectivity: 8 This goes up from a 3 to a 8. Why the big jump? No Citizen has not updated the app. I have been in touch with a very helpful person from Citizen who I have talked to on the phone a few times and what she told me was they had not seen the issue I was having that the app would actually crash, and they questioned if my phone was faulty. I did a factory restore and loaded the app and still crashed. I was having other issue with my phone which lead me to believe it in fact could be HW with my phone and not the app. I took my iPhone back to the Apple Store last night. I have played around with the app trying to get it to crash and I was not able to.

Connect and reconnect works much better. Once I had to turn scan off and back on to get it to reconnect, but the connection is much better and I do not have as many disconnects as I have before with the phone and the app.

Overall: 8.5

This is a increase from a 7. I really like the watch, the ability to have my phone in silent mode and know when the phone rings is incredible. It has come in handy many times already. I still keep the email notifications off but default, but have it configured in the event I am expecting an email and want to know when I have new emails. But then again, with the 80-100 emails I get a day this feature really is not important for me.

I do think they really need to add text notification. There are some other Bluetooth watches coming to the market, that are less than half the price and if Citizen really wants to compete with them, they need to add this feature.

Highly recommend this watch.


I just purchased the watch last night and wanted to give my first impressions, with an update to my review in a few weeks.

I will be using a scale of 1-10.

Look: 8
I am a techie and think the watch looks very nice. I like the layout of the dial. It look techie enough but also a watch I can wear with anything. Its a little big, I wish they would have somehow made the watch a little thinner. Its been a while since I have worn a watch on a daily basis so its going to take a little while to get use to.

Feel: 7

I wish the band was different, with the notches a little closer to give it a little more flexibility for adjustment on the wrist, its either slightly too tight or slightly too loose. Will take some time to break in.

Functionality of watch ( non bluetooth mode): 8
It does everything I want a watch to do. It tells time, shows me the date, and like how it shows you the battery life so you know when you need to charge it. I have looked at other Citizen Chronograph watches, many of them, even though they look nice, would have functionality that I really would not use.

Functionality (bluetooth) when paired: 9
I think this is great, I always have my phone in silent mode and do not have it on vibrate because when I am at work the one thing that drives me crazy is hearing cell phones ringing all the time. But I have a child and my father calls me all the time and in the event of an emergency I don't want to miss a call. Many times a week I will pull my phone out of my pocket and see how I missed phone calls. I love how it vibrates to let you know you have a phone call and the second hand stops at the 11 hour spot to let you know you missed a call. The email notification is cool but I have that turned off by default. You can configure it to check your email at 5,15,60,120 minute intervals. If I am expecting an email that I want to get, its easy to turn this on and have it vibrate to let you know you got a new email. I like the fact it does not keep a contact connection to your email so the watch is not vibrating nonstop.

Functionality ( bluetooth) connectivity: 3
Citizen has a lot of work to do in this area. Pairing is pretty straight forward, I did have some issues with pairing at first. The app would scan for the phone and you can see it tried to pair, the screen would dim for a second and then would continue to scan. Quitting out of the app and turning off bluetooth and restarting the app and trying again worked.

My biggest issue is re-connecting. Many times when I put the phone in activation mode, which is a simple process, but the app does not reconnect. In order to re-connect it, you need to kill the app by double tapping the home button and quitting the app. turn bluetooth off, open the app, have it tell you bluetooth needs to be turned on, click on to open settings and turn bluetooth on and then repair and hope it works. I have had issues with the app crashing on me when trying to pair and its frustrating, so I give this a 3 because its not reliable. For the most part once its paired and connected it works, I did have two instances this morning where it lost connection, the phone vibrated to let me know and the second hand was at LL for lost link.

I am a techie and love cutting edge technology, I am just hopeful that Citizen will be able to update the app to make the reconnection more reliable as well as hoping to see Citizen add new functions to the app to make this watch even better.

One suggestion I would have for Citizen is the vibrate notifications, I would like to see 2 vibrates for calls and one vibrate for emails or calendar, or maybe three for calendars, so that way you can tell what the watch is notifying you of without looking at the watch. With email alert on there is no way to tell if you have a call or new email without looking at the watch.

UPDATE: I sent an email to Citizen customer service and quickly received a response. This re-connect issue is only with the iPhone5 they say. They told me that somehow the bluetooth key gets corrupt. At the end of this review I will attach the text they sent me to re-connect.

Overall: 7
I would give it an 8 or 9 if/when Citizen fixes the bluetooth connectivity issues.

iPhone 5 issue workaround.

This occurs as the stored Bluetooth key in the iPhone has become corrupt. This appears to be affecting iPhone 5 users and not iPhone 4S users. To recover from this:

Shut down the app
Quickly press and release the home button on your iPhone,
Press and hold the Proximity App until a "-" symbol appears
Tap on the "-" symbol to close the app,
Press and release the home button on your iPhone to return to the home screen

Tap on the 'Settings' App of the iPhone
Tap on Bluetooth
Tap on the Eco-Drive Proxi..." device
Tap on 'Forget this Device'
A pop up towards the bottom of the screen will appear. Tap on 'Forget Device'
You will be returned to the Bluetooth Device screen

You may also see a device displayed as 'Peripheral'. If so:
Tap on 'Peripheral',
Tap on 'Forget this Device'
A pop up towards the bottom of the screen will appear. Tap on 'Forget Device'

Press and release the iPhone home button to return to your iPhone home screen
Tap on the Proximity App
Turn Scan 'ON'
Pull the crown out one 'click' and rotate the crown so the mode hand is pointing to 'PR' (pair mode).
Push the crown in one 'click'

A pairing notification will appear on your iPhone
Tap on Pair
The watch and iPhone will pair
You should now see 'Proximity Connect' on your Proximity App and the hand at the 2:00 sub dial on your watch should now be indicating between 1:00 and 6:00.

If you get an immediate Link Loss notification on your watch after pairing:
Press and hold the upper right button for 2-3 seconds to clear the notification on your Proximity Watch
Make sure Scan is 'ON' in the Proximity App
Press and release the upper right button to initiate a connection.
You should now see 'Proximity Connect' on your Proximity App and the hand at the 2:00 sub dial on your watch should now be indicating between 1:00 and 6:00.

To Finalize setting:
On your Proximity watch, Pull the crown out one 'click"
Rotate the crown to change modes to the TME (Time) mode
Push the crown in one 'click'

This completes this procedure

HASH(0xa7e449bc) out of 5 stars Very well-designed watch that talks to your iPhone June 28 2015
By Wise Young - Published on
Verified Purchase
This is a Citizen Eco-Drive watch with an interesting twist. The "Proximity" watch connects to your iPhone through low-energy bluetooth 4.0, automatically sets your time and date from the iPhone, vibrates when your iPhone receives calls or emails, allows you to connect and disconnect the watch from the iPhone, and can cause the iPhone to sound a sound signal so that you can find it. Like all Citizen Eco-drive watches, the Proximity watch recharges itself through light and should not need a battery change. When fully charged, the watch can run up to 6 months without light. Although it sets its time from the iPhone, you can also set its time and calendar manually. The watch has a stopwatch function. It has a perpetual calendar, a date display, can tell you the month and weekday, and also indicates how many years it is from the most recent leap-year. It is water resistant up to 100 meters.

I travel a lot around the world. For close to a decade, I have worn a Citizen Titanium Skyhawk A.T. Atomic Eco Drive Watch. It is a great watch, light, always charged, and always on time due to its ability to update itself through radio connection around the world. However, the watch has one major drawback. I have to set the time of the watch when I go to a different country. Setting time on the watch is not simple. For example, every time I flew from New York to India, I must pull out the crown, set the mode, push both buttons to get it out of local time, push one button 10 times to set the location to DEL, push both buttons to get it back into alternate time mode. If daylight savings time is in effect in the U.S., I must switch the watch to non-daylight saving when visiting other countries not on daylight savings. I sometimes forget to adjust for daylight saving time and have missed calls and appointments as a result.

I carry an iPhone 5. The iPhone automatically sets itself to the correct local time as soon as it gets onto Internet almost everywhere in the world. I have long wished that I had a watch that could do four things. First, I want a watch that resets its time and date based on my iPhone, without having to worry about daylight savings and whether I am one day ahead or one day behind. Second, I want a watch that can remind me if and when I am leaving my iPhone behind. At least several times a month, I would leave home without my iPhone because I had left it charging on my desk. Third, there are times when I don't know where I put my iPhone and wished that I had an easy way to make it ring, without having to ask somebody to call my iPhone. Finally, I want to know if somebody is calling my iPhone or I have a calendar appointment when the iPhone is in my backpack or bag.

The Citizen Proximity watch fulfills all four of these wishes. After receiving the watch, I downloaded the Citizen Watch Ltd App 2.0 (Cal.W760) from the App Store, installed the App on my iPhone, set the phone to PR mode (for pairing), and turned on scanning with a slide switch in the App. About 10 seconds later, the App asked if I wanted to pair with the watch, the function hand on the right upper dial turned to the 12:00-4:00 power charge position to indicate successful bluetooth connection, and the second hand of the watch moved to 8 o'clock position called ACT, and the watch reset its time and calendar according to the iPhone. If I forget the iPhone, the watch gives two vibratory taps (and the iPhone will sound a tone) to tell me that bluetooth disconnected. If I press both watch buttons, the iPhone wakes up and plays the Under the Sea Mermaid tune until I go to the Proximity App and press an OK button to turn it off. It does so regardless of the sound setting for the iPhone. Finally, the watch notifies me when I get phone calls on the iPhone.

There are two versions of the CITIZEN Eco-Drive Proximity App, version 2.0 and then version 2.5, which came out in March 2015. Version 2.0 works fine on my iPhone 5 running iOS 8.2. It watch lost the bluetooth link every hour or so and I would just pull the stem of the watch out and press it back in to reconnect it to the iPhone. When I tried version 2.5, it asked to upgrade the firmware in the watch. When I said yes, the App v. 2.5 said that it could not do so without charging the watch fully. I hung the watch close to a 40 watt bulb all night. In the morning, with the watch fully charged, I loaded the new firmware. It took 15 minutes but it was worth it.

The 2.5 version uses the bluetooth function of the iPhone to connect with the watch instead of the App. This gave better and more prolonged bluetooth connections for up to 6 hours (the watch apparently disconnects after being continuously connected for more than 6 hours). The watch would still disconnect sometimes but reconnected automatically immediately and the App was much more stable.

Some people complain that the mail notification function doesn’t work well. This has not been my experience. I set the watch to poll my Apple iMAP account every 5 minutes and to notify me when I have email, using the same iMAP server and server port used by the Mail program. The watch received timely notifications of email received by the iPhone. When I receive an email, the watch vibrates and the second hand points to the email/event notification at 10 o’clock and stays there. To tell you the truth, I have turned this function off because I don’t want the watch to notify me every time I get an email. This is different for phone calls. I don’t get many phone calls and want to be notified if I have a call. I also want to be notified of a calendar event.

Others complain that the watch often disconnects from the iPhone, especially when the 2.0 version of the App is used to connect to the watch. Indeed, the watch does disconnect from the iPhone every hour or so To tell you the truth, I don't connect the watch to the phone unless i am expecting a call. The Bluetooth connection wears down batteries of both the watch and the iPhone. The length of time that the watch can continue running in the dark when the bluetooth connection is on is about half the time when it is not on. You can tell at a glance whether the watch is attached to the iPhone. If I need the watch to attach so that I can update the time and calendar or when I am expecting a call, I simply pull out the stem to the first click (Position 1) and then push it back in. The function needle will show reconnection and the second had moves to the 8 o’clock position, indicating that the watch is updating its time and calendar from the iPhone.

If you use an Android phone and want the Citizen Proximity watch to link to your phone, you are out of luck. Citizen does not provide an Android App for connecting to the Proximity watch and their web site states that they are not aware of any third party that is offering such an App. I don’t know why Citizen has not made an Android App. In theory, it should not be difficult to write an App for Android that would update the time on the watch. Based on personal experience, I can say that Proximity watch works well with the Proximity App version 2.5 on my Apple iPhone 5 with iOS 8.3. According to the internet reports, the Proximity watch apparently works well with iPhone 4S, 5S, 6, and 6-plus. I have not tried connecting the Proximity to an iPad or iPod although the manual for version 2.5 of the Proximity App says that it will pair with iPad 2 forward and iPod 5th generation operating iOS 7.0.4 or higher, although Citizen says that use of their App on these devices is not supported.

The nylon-backed leather band is presumably tougher than an all-leather band. The nylon part is green and is on the inside of the band facing the skin while the black leather part faces outward. The leather is black and appears to have been treated so that it is waterproof and does not feel like leather but does have the smell of leather. The leather is perforated and the nylon layer is sewn to the leather layer with green thread. I don't think that the perforation makes much difference in terms of cooling or aeration since the nylon layer would prevent any air movement. The band was made in Thailand. The band looks like it will last a while and is reasonably comfortable to wear.

The watch itself is relatively thick with a stainless steel case and the back announces that the movement was made in Japan. The watch is black ion-plated, very solid, and looks like it can withstand being run over with a truck. The serial number has an slight indentation on the right side, which indicates that the watch has the latest firmware from 2015. If the indentation is on the left side, it means that the watch has firmware from 2014. According to Citizen web site, firmware changes must be made at the factory. There are many warnings on the back of the watch saying “DO NOT OPEN. SERVICE CENTER REPAIR ONLY”.

The face of the watch is attractive with three inner dials. The hands, dials, and hour markers have green highlights and white luminescent markers that can be seen in the dark. The hour and minute hands are skeletal so that the dials underneath can be partly seen. A left upper dial gives local time in a 24-hour clock. The right upper dial has a function hand with three modes: a timer clock indicating up to 60 minutes, a blue-tooth on (12-4 o’clock) and off (7-10 o’clock) mode which also shows the charge status of the watch, and a calendar mode where the function hand points to the day of the week. A lower dial shows the modes, including CT (connect), PR (pairing), and DCT (disconnect), >0< (zero mode), L-TM (local time), CHR (chronograph), CAL (calendar), and TME (time).

The right side of the watch has two black buttons and one winding crown with a green stem. The crown can be pulled out one click (Position 1) which allows you to set the mode, shown in the lower dial. If you pull the crown one more click (Position 2), you can turn the stem to change the time (TME, L-TM)) and date (CAL) manually. The top button allows you to reset the pairing (by pressing it for 7 seconds in the PR mode). Pressing the top button once will reconnect the watch to the iPhone if it has disconnected. If you press both buttons, it sends a message to the iPhone to play the Mermaid song until you open up the Citizen Proximity Ap and press Okay button to stop the song.

So, why would one want to buy this watch as opposed to an Apple Watch, which has more functionality and can monitor movement and other body functions? The Citizen Eco-drive watches are probably the most practical and care-free watches in the industry. The watch is very tough, water-proof to 100 meters, and self-charging. Just wear the watch in the presence of light and it should keep excellent time and provide you with accurate time, day, and date. Once you have set up the Citizen Proximity watch, you don’t have to do much to keep it going and access all its functions. You connect to the iPhone to update its time and calendar or when you are expecting a call or calendar notification.

In contrast, if you have an Apple watch, you have to take it off every night and charge it. The Apple watch is not waterproof and not as tough as the Citizen Proximity watch. You have to spend a lot of time on your Apple Watch, learning and manipulating the software on it. If your goal is to simplify your life, the Citizen Proximity watch does so. You don’t have to worry about charging your watch. You don’t have to reset your watch every time you travel somewhere. It will connect to your iPhone to update your time and calendar. The watch will remind you when the watch is not connected to the iPhone and even allow you to find the iPhone. Finally, you can do most of the other functions of the Apple watch on the iPhone itself.

The list price of the Citizen Proximity watch ($490) on the Citizen watch web site is higher than that of the lowest price Apple Sport watch ($350). However, I bought the Citizen Proximity watch for $363.77 on Amazon. You will not be able to find discounts on Apple watches. So, the Citizen Proximity watch is similar in cost to the lowest price Apple watch. The following picture is a view of watch phase that is not normally seen, showing the four signals from the iPhone that the second hand points to on the left side of the watch for ACT (synchronizing the calendar and time), LL (bluetooth link lost), MAIL (mail and also calendar events), CALL (iPhone call); the function hand in the right upper dial points to the power gauge when the bluetooth link is on. The mode dial shows that hand pointing to CT or connect.

HASH(0xa7bba1c8) out of 5 stars Works okay, better than what I expected. Dec 19 2014

Verified Purchase
This watch actually works better than what I expected after I read some of the bad experience from previous.
Since different user have different setup, so I am going to detail what I have, and what my experience is.
iPhone 6 Plus 64GB running iOS 8.1.2
I purchased the watch from Amazon (not third party seller) came loaded with Firmware. (Purchase made Dec 2014)
You can tell by the little dot indentation by the end of the Serial Number String.
With this Firmware, you can update the Firmware with the iOS app. (please note, this watch does not work with Android at all, don't even try)
DO NOT download or use the previous version of the app, which the icon has a white background
ONLY use this one app called "Citizen Eco-Drive Proximity 2.5" at the app store, the icon has blue background
1. Once you've install the app, make sure your bluetooth radio is turned on with the iPhone, AND your phone has to be plugged in (even with more than 50% charged).
2. Now, pull the crown on the watch, just the first "click", not all the way, and turn the crown until you see the lower dial goes to "PR"
(if it is already in PR mode, you still have to pull the crown at first click, and push it back to "restart" the PR mode)
3. Push the dial back all the way, and now your watch is ready to be connected.
(DO NOT try to pair your watch using the Bluetooth function with iOS if you have firmware and lower!)
4. Now, launch the Citizen Eco-Drive Proximity 2.5 app
5. If the app does not automatically try to check the firmware, click on "Check for Update" manually.
6. The app now will try to connect to the watch and detect if the watch is at
7. For my case, it is at, so it will prompt me if I want to update to
8. Since most likely, the watch was sitting inside the packaging for all these time, it might not have enough charge from light, so the app will also tells you you don't have enough charge and cannot perform the update.
For me, to resolve this, I just let the watch sit under some strong light source, (for myself, I use one of those small LED flashlight, let it shine directly to the watch for 2 hr)
Now it should have enough charge (if not, "light charge" it again for longer)
Start from Step #1 again, for me, it will start updating the firmware when you have enough juice in the battery from light.
It takes around 10 minutes to complete the update, and the reason why the app need the phone to be plugged in for this process is because it will keep the iPhone screen on for the entire process.
Once the process is done, make sure it is in PR mode, pull the crown at first click, and push it back to "restart" the PR mode.
NOW, go to your iPhone bluetooth settings, and pair your watch, now you're ready.

1. It DOES NOT automatically reconnect if disconnected, always need to be manually reconnect. Manual reconnect always connect with exception (see #5 below)
Update: PLEASE NOTE, when reconnect, always press the upper button, and count 3-4 seconds, if the seconds hand didn't move to ACT indicating reconnection process is undergoing, release the button and try again. DO NOT press the upper button for longer than 6 seconds as that will wipe the bluetooth pairing information on the watch.
2. It randomly disconnected 2 times over 24 hrs, and was able to reconnect by pressing on the upper button for 3 seconds
3. It WILL disconnect after 6 hrs, this is by design, and you can always reconnect by pressing on the upper button for 3 seconds
4. It WILL disconnect if the iPhone is more than around 5-6 feet away from the watch.
5. If it is disconnected, DO NOT (remember DO NOT) try to connect using your iPhone's bluetooth settings (by clicking on "Eco-Drive Proximity" item on your bluetooth setting). If you do, it will NEVER connects again until you power cycle your bluetooth radio on your iPhone (turn off and on). After that, click on the upper button to reconnect.
6. If the seconds (as in time, not seconds as in numbers) hand stays at LL mode indicating Loss Link, press lower button for 3 seconds, so it will go back to normal seconds reporting, then, press on upper button for 3 seconds to reconnect.
7. The stitches on the underside of the watch band is not too comfortable, kinda scratches me, but that's okay, I can always change the band if needed
8. The charge level remain "FULL" from the indicator after 24hrs. (I turned off mail notification since I got way too many ad mails)
9. I tried to adjust the time on my iPhone (switch to different time zone), the watch syncs with the time on the iPhone right away when I click on "General" to navigate away from the Date Time Setting.

To summarize my experience, it connects to my phone most of the time, I only need to manually reconnect when it turns off after 6 hrs (by design to save electrons) and that 2 random disconnect. (the random disconnect didn't happen again the following day)
Of course I need to manually reconnect when I intentionally walked away from my iPhone with my watch (it was a test).

My experience with this watch at Firmware seems to be okay.
Again, your watch will NOT connect with iOS8 if you're running firmware and below.
If you have, try update the firmware
If you have anything below, I would suggest returning it or send to Citizen for the firmware update.

Please also refer to the manual below if you have been using the older app and already paired (or other scenarios)
