Casio G-SHOCK 7900 Series a Digital Watch - G-7900-1

The Casio G-SHOCK G-7900-1 is a rugged digital watch designed for straightforward operation in cold, wet, and active environments. Its large front buttons and segmented LCD make common functions easy to find, while a tide graph and moon-data display add useful reference information for marine recreation.

Shock resistance, 200-meter water resistance, and low-temperature operation down to -20°C support demanding outdoor use. Two independent 1/100-second stopwatches, a 24-hour countdown timer, world time, and five multifunction alarms expand its timing capability.
