CASIO GW500A-1V Black G-Shock Atomic Solar Watch with resin band

The classic G-Shock watch goes 21st century! This updated version begins with the shock resistance and water resistance (up to 200M) you expect from the G-Shock, and adds the convenience of solar battery recharging (though even without a single ray of light reaching it, this battery will hold its charge for 11 months!), and automatic time correction, via radio signal, 4 times daily. Without calibration, this G-Shock is accurate to +/- 15 seconds a month. 30-city world time keeping, auto-calendar programmed to 2039, choice of 12- or 24-hour format, and on/off Daylight Savings Time functions. Your G-Shock will help you manage your work day as well as your play time with 4 available daily alarms, snooze, time recorder, and 3-mode stopwatch features. All of this functionality is at your fingertips with easy-to-understand controls, and backlight with Afterglow.
