From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes new coloring models. Bi-color molding makes it possible to create a new type of band with different colors for the inner and outer surfaces. The inside surface coloring is visible from the sides of the band and through the band holes for an original look. The military motif of these models is highlighted by their coloring, which recalls the inner lining of a flight jacket. The base model is the anti-magnetic GA-100 analog-digital combination watch, and the five models of this lineup are available in black, blue, orange, white, and beige. • Magnetic resistant • Speed measurement • 1/1000-second stopwatch SPECIFICATIONS Case size (L× W× H) 55 × 51.2 × 16.9 mm Weight 72 g Case and bezel material Resin Band Resin Band Construction Magnetic Resistant Shock Resistant Water resistance 200-meter water resistance Power supply and battery life Approx. battery life: 2 years on CR1220 Glass Mineral Glass World time World time 29 time zones (48 cities + coordinated universal time), daylight saving on/off, home city/world time city swapping Stopwatch 1/1000-second stopwatch Measuring capacity: 99:59'59.999'' Measuring modes: Elapsed time, lap time, split time Others: Speed (0 to 1998 units/hour), Distance input (0.0 to 99.9) Mach indicator (speed exceeding 1225 units/hour) Timer Countdown timer Measuring unit: 1 second Countdown range: 24 hours Countdown start time setting range: 1 minute to 24 hours (1-minute increments and 1-hour increments) Other: Auto-repeat Alarm/hourly time signal 5 daily alarms (with 1 snooze alarm) Hourly time signal Light LED light Auto light switch, selectable illumination duration (1.5 seconds or 3 seconds), afterglow Light color LED:Amber Calendar Full auto-calendar (to year 2099) Accuracy Accuracy: ±15 seconds per month Other features 12/24-hour format Regular timekeeping: Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (speed) Digital: Hour, minute, second, pm, month, date, day
