I never normally wear digital watches. I think they look cheap, nasty and tacky. I purchased this watch because I wanted a cheap "beater" with a good stop watch that is light so I could wear it whilst running or working out and wouldn't be affected by sweat. I also wanted something really tough that was water and sand resistant because I'm going on a cruise around the South Pacific soon and will be spending a lot of time in salt water, snorkeling and doing stuff in "beachy" places. I really didn't want to wear my Tag Heuer with gold plating in the salt water or on the beaches during the day in case it corroded the metal, ditto for my watches that have leather bands etc so I purchased this Casio Mudman brand new on Ebay for half of what they retail for here in Australia. (They retail brand new here for about $200 and I got mine for around $120 including postage from Hong Kong).
For what it is this watch is a quality piece of equipment. It is tough and very well constructed, you can feel that as soon as you pick it up. It is water resistant to 200 meters and is shock and mud or sand proof as well. It actually looks quite nice although you couldn't wear it with a suit. It is a big but not huge watch and I don't have a massive wrist although for some reason it doesn't look too big on me which I'm glad about. It has a couple of stop watches, world time functions for a ton of cities, several alarms, countdown timers, day date and month- pretty much all you need for a tough, sporty kind of watch. Although I haven't put it to any "test" yet, you can just feel the toughness of this watch, I really think it could take a lot of punishment although I probably won't be subjecting it to anything out of the ordinary.
Anyway, as a sporty, tough, rugged kind of watch that you can wear without worry of scratching or damaging, this Casio Mudman really fits the bill. 5 stars for what it is.
