Silky smooth with pearly luster — a soft, subtle, and sophisticated timepiece from Casio G-Shock. Pearlescent polarized coatings with a matte finish that change in appearance depending on the viewing angle are applied to the bezel and band. Gorgeously radiant metallic colors are used for the dial. A half-matte finish applied to the index marks and dial with vapor deposition leaves a subtle luster, adding a touch of brilliance to the simple appearance of the minimalist design. Key resin components used in the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.Case size (L× W× H): 46 × 40.2 × 11.2 mmCase and bezel material: Resin / Bio-based resinBand: Bio-based resin bandConstruction: Shock ResistantWater resistance: 200-meter water resistancePower supply and battery life: Approx. battery life: 3 years on CR1025Glass: Mineral GlassCompatible band size: 145 to 190 mmOther: NeobriteWorld time: World time 31 time zones (48 cities + coordinated universal time), daylight saving on/offStopwatch: 1/100-second stopwatchTimer: Countdown timerAlarm/hourly time signal: 5 daily alarmsLight: 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: WhiteCalendar: Full auto-calendar (to year 2099)Mute feature: Button operation tone on/offAccuracy: Accuracy: ±15 seconds per monthOther features: 12/24-hour formatCasio G-Shock Style #: GMAP2100ST-7A...
