    • Watch
Love the watch so far. It looks great it feels great. A few people compliment me on it. The design is very unique and as eye-catching. The luminescence on the hands is very bright. It's easy to program. So far I'm very happy with my purchase

First things first, this watch is beautiful. I love how it looks on my wrist and I like that it isn't completely gargantuan like some other G-Shock analog watches. The dial is a pleasure to look at whenever I need to check the time. Since this is the non-metal version, it's relatively light and not fatiguing to wear. The lume is fantastic on the hands and charges via both natural and artificial light. I have no issues reading the time at night. I've owned a few Casios, and aside from 1 outlier, they generally stay dead accurate on time. This one doesn't appear to be an outlier and is still giving me the correct time to the second after wearing it for about 3 weeks. My only gripe is usability of the other features on the dial like the day subdial and the digital readout. I should have figured based on the design, but the hands block these features throughout the day. If I forget the date or want to use the stopwatch while one of the hands is blocking my view, I have to press light + mode to get the hands out of the way. Then, do it again to move it back. It's nice that they give you a way to do that, but it just feels like a bandaid on a design flaw. If I discovered this quirk on a full metal version of this watch that retails for 5-6x more, I'd probably return it. So I'm actually really glad that this is the first GA2100 I've bought. At this price, I'm more than happy with the rest of the watch that I'd still recommend it. I purchased this while $133, but I'd be willing to spend up to $150 if I had to do it again. To sum up, this is a fantastic watch for active lifestyles or just EDC. Between the looks and overall build quality, this is an easy watch to recommend for most people. ... show more

    • Crystal too dark
The crystal is so dark that you cannot read the information presented in the face without a direct outside artificial source of light. Even the internal light does not help.
