Brand new, complete set A multicolor carbon-insert bezel, crafted of layers of carbon and glass fiber sheets containing phosphorescent particles, evokes the massive explosive power of the sun’s surface, yielding a timepiece that radiates with glow-in-the-dark beauty. Individually and uniquely patterned bezel components — no two alike — result in truly one-of-a-kind lightweight watches of rugged strength. Take it even higher with the GWG-2000 bezel components, made of forged carbon fiber with phosphorescent particles to match the bezel with solar flare patterns that glow in the dark. 61.2 × 54.4 × 16.1 mm Weight 112 g Case and bezel material Resin / Stainless steel Band Resin Band Construction Shock Resistant Mud Resistant Carbon Core Guard structure Water resistance 200-meter water resistance Time adjustment Radio-controlled Watch; Multi band 6 Power supply and battery life Tough Solar (Solar powered) Sensor feature Digital compass Measures and displays direction as one of 16 points Measuring range: 0 to 359° Measuring unit: 1° 60 seconds continuous measurement Hand indication of north Bidirectional calibration Magnetic declination correction Altimeter Measuring range: -700 to 10,000 m ( -2,300 to 32,800 ft.)
