I've had this watch for about a month now and am VERY happy with it... feels solid, screen is easy to read, setting the time was simple (don't even have to leave it in the window, updates every night just sitting on my nightstand). Only times the time hasn't updated automatically is if I have it on my wrist while sleeping and have my arm under the pillow.
Solar charger works great... was on Medium charge. Left it for an hour and a half in the window in bright sunlight, and hasn't come off full charge since (and I often wear long cuffs working indoors, so it doesn't get a ton of light exposure).
Only 3 minor reasons for not giving it 5-stars:
1. band could be a bit longer... I have large wrists and have to have the buckle on the last hole or two to fit. Not a major complaint but an extra hole or 2 would be great
2. time zones... I live in Saskatchewan and we don't change for daylight savings. This means for part of the year, I have my time zone set for Denver, and for the other half, I have to set it for Mexico. Just would be nice to have a zone that I don't have to readjust.
3. alarm is very quiet. Good to notify you if you're watching TV or in an office/meeting, but if you're asleep it likely won't awaken you (and I'm a light sleeper), if you're in a noisy environment our outside in the cold with a heavy jacket over your arm, likely won't hear it.
All in all,,, great watch!
