Amazon.com Product Description:
This Casio men's watch has a titanium case and bezel that reduces weight while maintaining the shock resistance that G-Shock watches are known for. The watch is solar powered that allows the watch to run for nine months on a full charge without further exposure to light. The watch calibrates itself via radio signals to the US atomic clock for unsurpassed accuracy. It features five daily alarms, a countdown timer, a stopwatch, auto electroluminescent backlight with Afterglow, a calendar pre-programmed until 2099, a battery power indicator, and a power saving function. A deep waved black resin band provides a secure fit and the watch is water resistant to 660 feet (200 meters). It is covered by the manufacturer's 1-year warranty.

I bought this to replace a dead Casio G-Shock that had served me well for over 10 years. That one was a replacement for another that had also lasted over ten years, so I am into my 3rd decade of Casio watches. I like the radio link to the atomic clock. That's a minor laziness issue, but convenient. I like the idea of the solar thing although I am not yet convinced that I gain much from that.

A couple things I don't like about this:
1)I use this watch primarily while I am jogging. I jog 30 minutes...15 minutes out and 15 minutes back. The countdown timer on my previous G-Shock was set at 15 minutes and it told me when to turn around. Then the timer restarted itself and told me when to stop. The new one doesn't restart so it is now set at 30 minutes and I watch the time for when to turn around.
2)When the timer goes off the light doesn't flash. Sometimes I jog after dark and want to see the face of the clock, especially current time in the second little window. This is also a change from the previous model.
