Comment: I like this watch, but it's not perfect. The tough solar and atomic functions work great. Although it has 5 alarms (4 and a snooze alarm), it doesn't have a countdown alarm.
My previous solar-powered G-shock only lasted 6 years before the battery died. Is that the 'lifetime' of the product, as the tough-solar claims? It was not easy to find a replacement battery for that older watch, and I've heard that water resistance often fails after opening the watch up to replace the battery. You're supposed to change out the rubber seals inside every few years too, but that doesn't appear easy or plausible. It's not like there's anyplace online where you could buy them, for example.
For a G-shock this watch is actually fairly small, but compared to most watches it is indeed bulky. It's smaller than my last watch so I like that.
The backlight on this watch is fantastic. It also grabs an atomic signal several times during the night instead of once, making it much more reliable than previous versions.
Customer Rating: Summary: Awesome
Comment: I bought this G-Shock to replace my (still running!) 15 year old G-Shock watch. While the old unit still runs, I found that the protective rubber that encases the electronics of the watch was starting to fall apart, so the watch is essentially exposed now. It still looks like it could take a beating, but there are exposed metal rivets that keep on snagging on things. Those rivets tend to get caught in your sleeves and will start to tear the fabric over repeated wearings, so I finally gave in, and bought this new model.
Of course the new model is just as G-Shock tough as my old unit, and I'd expect no less. But in the world of electronics, 15 years is a long time, and this new watch eclipses the old one with it's new features.
First, the solar charging is awesome. You can put it out in the sun for about 10 minutes, and that charge is long enough to last a week. Keep in mind when you first get it, you'll probably need to charge it for a bit longer though, probably 45 minutes to an hour.
Even better, this thing synchronizes with the atomic clock in Colorado (forgot the name, the main amazon product page has it though) so it's super accurate. The synchronization is the reason that you have to keep this unit fully charged, though. To preserve battery life, once the battery reaches 50% capacity or less, it will no longer attempt to synch. With my old watch, I always knew that it the time wasn't 100% accurate, and I took the time it indicated with a grain of salt. With this guy, when I look at the time, I know that it's right to within millisconds.
There are a lot of neat other features that this watch has that the old one didn't have as well. For instance, you can set the backlight to automatically light up, depending on the angle of your wrist, without having to press a button. More gimmicky than necessary, but it's fun to show off to friends.
All in all, for the price of the purchase, the watch is well worth it, especially considering that I expect it to last me at least as long as my old G-Shock watch!
Customer Rating: Summary: Great Watch
Comment: I bought the watch about 2 months ago. I've had no problems and it has been great! Looks great too.
Customer Rating: Summary: Nice Watch
Comment: Watch works as advertised. Synchronization keeps it accurate. Easy to read display. Took 1 star off because I think the watch will last longer than the band.... then what.
Overall it looks good, and is probably a good rugged watch
