Casio G-Shock

Description

The Casio G-Shock GA-100GGB-1A9ER is a bold men's watch that makes a striking statement with its all-black resin case and eye-catching gold-tone accents. The gold-tone vapour deposition and gold-tone mirror LCD give the dial a distinctive, refined shimmer, while the glossy coating on the strap and case creates an elegant overall appearance.

In addition to analogue timekeeping via two hands, the watch offers a digital display for hours, minutes, seconds, month, date and day of the week. World time for 29 time zones, a 1/1000-second stopwatch with Mach meter function, a countdown timer, five daily alarms and a fully automatic calendar until 2099 complete the package. The yellow LED backlight with auto function ensures excellent legibility even in the dark.
