Casio G-SHOCK GULFMASTER GWN-1000B-1BJF Solar Watch
Casio G-SHOCK GULFMASTER GWN-1000B-1BJF Solar Watch
The Casio G-SHOCK GULFMASTER GWN-1000B-1BJF is an analog-digital Master of G watch developed for demanding marine and outdoor environments. Powered by Casio’s Tough Solar system, it combines Multi-Band 6 radio-controlled timekeeping with shock-resistant construction and 200-metre water resistance.
Its black design is distinguished by a blue-toned bezel and a highly functional analog-digital dial. The resin and stainless-steel case measures 44.9 × 55.8 × 16.2 mm and is fitted with mineral glass and a durable resin strap. Double LED illumination, Neobrite hands and markers, and a hand-shift function help maintain visibility in changing conditions.
Casio’s Triple Sensor Version 3 provides compass, altimeter, barometer and thermometer functions. Marine-focused features include a tide graph and moon-age display, while the barometric pressure tendency alarm warns of sudden atmospheric-pressure changes. World time, alarms, a stopwatch and countdown timer add practical everyday functionality.
