Casio G-Shock CARBON CORE Mens Ana-Digi Red Watch GA2100-4A

G-Shock's new GA2100 series contains watch models that take on the octagonal shape that was originally part of the popular DW5000C collection. An analog-digital Japanese quartz movement lays inside the minimalistic design all while withholding the level of toughness G-SHOCK has come to be known for. A super-strong resin case and strap are reinforced by carbon fibers which allow the case to sit at a mere 11.8mm of thickness, which is as thin as a G-SHOCK combo model can get. 48.5×45.4×11.8mm Black Resin Case Tough Resin Strap Red Analog-Digital Dial w/ Negative LCD Display Shock Resistant Mineral Glass 200-meter water resistance 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) World time: 31 time zones (48 cities + coordinated universal time), daylight saving on/off, Home city/World time city swapping 1/100-second stopwatch Countdown timer 5 daily alarms Hourly time signal Hand shift feature Full auto-calendar (to year 2099) 12/24-hour format Button operation tone on/off Regular timekeeping Analog: 2 hands (hour, minute (hand moves every 20 seconds)), 1 dial (day) Digital: Hour, minute, second, pm, month, date Accuracy: ±15 seconds per month Approx. battery life: 3 years on SR726W × 2
