Casio G-Shock Metal-Clad Octagonal Silver/Black Mens Watch GM2100-1A

New black band and silver stainless steel bezel GM2100-1A in a metal-clad octagonal take on the original iconic design. Forged in stainless steel with rounded hairline finish, the strong bezel says super style all the way. The dial is treated with vapor deposition finish for a meticulously detailed metallic look that suits a classic metal G-SHOCK timepiece. Incremental variations in the detailed square dot texturing on the wristband take casual urethane materials up a notch. 49.3 × 44.4 × 11.8 mm Weight - 72 g Case and bezel material Case / bezel material: Resin / Stainless steel Band - Resin Band Shock Resistant Water resistance -200-meter water resistance Power supply and battery life - Approx. battery life: 3 years on SR726W X 2 Glass - Mineral Glass World time World time 31 time zones (48 cities + coordinated universal time), daylight saving on/off Stopwatch 1/100-second stopwatch Measuring capacity: 00'00''00~59'59''99 (for the first 60 minutes) 1:00'00~23:59'59 (after 60 minutes) Measuring unit: 1/100 second (for the first 60 minutes) 1 second (after 60 minutes) Measuring modes: Elapsed time, split time, 1st-2nd place times Timer Countdown timer Measuring unit: 1 second Countdown range: 24 hours Countdown start time setting range: 1 second to 24 hours (1-second increments, 1-minute increments and 1-hour increments) Alarm/hourly time signal - 5 daily alarms - Hourly time signal Light - Double LED light LED light for the face (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow) LED backlight for the digital display (Super illuminator, selectable illumination duration (1.5 seconds or 3 seconds), afterglow) Light color - LED:White Calendar - Full auto-calendar (to year 2099) Mute feature Button operation tone on/off Accuracy - Accuracy: ±15 seconds per month 12/24-hour format Hand shift feature Regular timekeeping: Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (day) Digital: Hour, minute, second, pm, month, date
