G-Shock G-7900 Rating by G-Central
The G-7900 offers has useful and unusual features but it is a bit hampered by its short battery life. The GW-7900 offers similar functions along with Tough Solar and Multi-Band 6, but it doesn't have the multiple stopwatches, multi-function alarms, and flash alerts of the G-7900.
