I've been wearing a Casio, solar-powered atomic watch for three years already:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Casio-Men-s-GW1400DA-4AV-G-Shock-Atomic-Solar-Watch/dp/B000FF8QXI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Casio Men's GW1400DA-4AV G-Shock Atomic Solar Watch</a>. When this one showed up on a Black Friday deal, I decided that one of our kids should have it. All I can say is that we are quite happy with our purchase.

What I like the most about a watch like this is that, once set, it becomes almost completely maintenance-free. You will never have to worry about replacing batteries or adjusting the time. That happened to be the case with my old Waveceptor. The watch comes with a manual that describes all functions and features in detail in both English and Spanish.

Briefly, this is what you get:

- Constantly sync'ed with an atomic clock in Colorado broadcasting the official US time so it's always accurate within 1/100 of a second IF it can sync successfully.
- Optionally it can get sync with atomic clocks in Japan or England, if you happen to be in the area.
- Charges itself from 'light'. 5 minutes in the sunlight daily is all that's needed for the watch to work forever. Alternatively, any exposure to light will charge the battery a little but if all you have is fluorescent light then you will need up to 8 hours of exposure.
- Shows time in a number of world cities.
- Auto-adjust for DST for most cities.
- Stopwatch for up to 1000 hours.
- Countdown function.
- 5 (five) separate alarms.
- Illuminated face.
- Allows for manual setting of time if needed.
- Water resistant up to 100m - you can wear it while snorkeling but it's not recommended for scuba diving.
- All digital.
- Light weight.

The watch comes with a 1 year warranty but they do not cover damages caused by abuse, neglect or fire. You will also need some proof of purchase.

My kid loves it so it's a 5-star.
