I've had this for about a month. It's my third G-Shock but my fourth Casio with the Wave Ceptor technology. NOTE: I didn't get this watch because the previous watches failed in any way. I simply got bored with them and wanted something new. Those others are still running just fine.

The watch is solar powered. Mine arrived with the battery on medium charge, but after a few days of exposure to the Florida sun it oscillated between medium and high, then settled on high. It's been on high charge ever since. I didn't do anything special to charge it up, I just wore it as I would any other watch.

This watch syncs with atomic clocks around the world. It hasn't failed to sync a single day since it arrived. Imagine that! My watch keeps perfect time. If there's ever a dispute at work about what time it actually is, my watch settles the matter.

I haven't taken this watch off my wrist since it arrived. I wear it in the shower and make no effort to protect it from moisture, soap or shampoo. I know from experience with previous G-Shocks that I don't have to worry about water resistance.

The watch is relatively small and lightweight, but as my wrist is small I wear it pretty tight anyways (using the second from the last hole in the band). It doesn't shift or roll around or slide up and down my arm that way.

The watch is good-looking but the only thing that's easy to see is the time. By that I mean that the white hands stand out against the black background. However, it can be hard to see the data in the three little circular windows--in part because they're so small, but also because everything is so blacked out. You have to hold the watch just right under a decent amount of light to make out the date, day of the week and seconds count. Also, because this isn't a big flashy watch, you need good eyesight to easily see everything but the time.

The light is adequate for viewing the time but nothing else. Due to the contrast of the white hands against the universally black background, I rarely need to use the light anyway.

I will update this review if anything goes wrong, but based on my previous experience with G-Shocks I doubt I'll need to. I could not recommend this watch more highly. About the only thing it can't do is find my cat.
