Part of the MASTER OF G - SEA series, this Japanese Domestic Market model combines Tough Solar power, MULTIBAND 6 radio-controlled timekeeping and ISO 200-meter diving water resistance with a metal-and-resin composite band.\u003c\/p\u003e\n\n\u003ch3\u003eBlack Exterior with Tan Utility Accents\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePurposeful design:\u003c\/strong\u003e Inspired by tactical equipment, the restrained tan accents complement the black exterior. A DLC-coated bezel and black ion-plated front screws emphasize the metal details without adding unnecessary decoration.\u003c\/p\u003e\n\n\u003ch3\u003eTough Solar and MULTIBAND 6\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSolar-powered timekeeping:\u003c\/strong\u003e Tough Solar converts light into energy to power the watch. MULTIBAND 6 receives compatible standard time signals from transmitters in Japan, China, the United States, Germany and the United Kingdom. Reception depends on location, conditions and the selected home city.\u003c\/p\u003e\n\u003cp\u003eFrom a full charge, the watch operates for approximately 7 months without further exposure to light under normal function use, or approximately 23 months with power saving activated. Accuracy without signal reception is within ±15 seconds per month.\u003c\/p\u003e\n\n\u003ch3\u003eDiving Functions and Triple Sensor\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDepth, direction and temperature:\u003c\/strong\u003e The Triple Sensor measures water depth up to 80 meters in 0.1-meter increments, compass bearing and temperature. Automatic horizontal compensation supports compass readings when the watch is tilted.\u003c\/p\u003e\n\u003cp\u003eDiving functions include automatic measurement start and stop at a depth of 1.5 meters, dive-time measurement, surface interval display and an ascent-rate alarm. The log memory stores 20 dive records, including dive start date and time, dive duration, maximum depth and minimum water temperature.\u003c\/p\u003e\n\n\u003ch3\u003eSapphire Crystal and Composite Band\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eProtective construction:\u003c\/strong\u003e A stainless-steel case, screw-lock case back and sapphire crystal with an internal anti-reflective coating support the watch's ISO 200-meter diving water resistance. The case back carries the FROGMAN diving-frog engraving.\u003c\/p\u003e\n\u003cp\u003eThe composite band combines metal and resin components, with bio-based resin used in its main resin parts. A two-stage extension allows additional length over a wetsuit, while the clasp provides fine adjustment and a double-lock mechanism.\u003c\/p\u003e\n\n\u003ch3\u003ePractical Digital Functions\u003c\/h3\u003e\n\u003cp\u003eWorld time, tide graph and moon data complement the diving functions. A stopwatch, countdown timer, five daily alarms and timestamp memory add everyday utility. The white full-auto LED Super Illuminator backlight improves visibility in low-light conditions.\u003c\/p\u003e\n\n\u003ch3\u003eJapanese Domestic Market Model\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eJapan-market reference:\u003c\/strong\u003e GWF-D1000BC-1JF is the Japanese Domestic Market reference.
