Conquer even more terrain with enhanced support — A rugged timepiece in a bold, powerful, triple-sensor design. This G-SHOCK Master of G watch is developed for professionals working in the harshest environments with a mud-resist construction. The large, easy to operate front button and three direct sensor buttons on the side are shaped to drain mud and water and are protected by cylinder-shaped stainless steel components. The button shafts are equipped with gasket fittings to keep mud and dust out, as well, so you’re ready to take on the toughest of terrains. The bold design features a dual-layer LCD, as well as the Triple Sensor to deliver altitude, direction, temperature and barometric pressure readings directly to your wrist. The thin module and Carbon Core Guard structure mean all these features live in a slimmer, more compact watch, for tough and rugged support with a comfortable fit. The digital compass is more practical than ever thanks to the dual-layer LCD, which displays compass graphics on the top layer and time and other readings on the layer below. Taking utility to a whole new level, radio-controlled solar power delivers precision timekeeping powered by light, while Super Illuminator ensures visibility, even in dark places. The case, bezel and urethane band are made with bio-based resins derived from renewable organic resources. The case back is engraved with the iconic MUDMAN mole character holding a compass.Case/bezel material: Bio-based resinBlack Bio-based resin bandShock ResistantMud ResistantCarbon Core Guard structure200-meter water resistanceTough Solar (Solar powered)Digital compassMineral GlassWorld time: 31 time zones (48 cities + coordinated universal time), daylight saving on/offSunrise, sunset time display1/10-second stopwatchCountdown timer5 daily alarms (with 1 snooze alarm)Hourly time signalLED backlight (Super Illuminator)Full auto LED light, selectable illumination duration (1.5 seconds or 3 seconds), afterglowFull auto-calendar (to year 2099)Mute feature: Button operation tone on/offPower Saving (Turns off the display when the watch is left in the dark)Battery level indicatorTime calibration signal reception; Auto receive up to six times a day (remaining auto receives canceled as soon as one is successful)12/24-hour formatRegular timekeeping: Hour, minute, second, pm, month, date, dayDuplex LC displayCase size (L× W× H): 56.7 × 52.7 × 14.8 mmG-Shock Style #: GW9500-1
