Casio

Built for maritime rescues or adventures, Casio G-Shock's Gulfmaster collection consists of timepieces designed to withstand rigorous conditions at sea. The Quad sensor now includes a depth sensor, digital compass, barometer/altimeter, and thermometer, all features that provide vital information concerning the constantly changing conditions at sea. For easy visibility after dark, this watch also boasts a double LED light, one for the face and one for the digital display. Keeping in time with Casio's time honored tradition of toughness, a shock resistant 48mm case protects the model. Finally, a black resin strap completes the look and comfortably secures the watch to its wearer.48mm resin caseShock ResistantTime calibration signal receptionDigital compassBarometer/AltimeterThermometerDouble LED lightSolar poweredDepth meterMoon dataTide graphWorld time 31 time zones (48 cities + coordinated universal time), One-touch UTC Time Zone Access, daylight saving on/off, Home city/World time city swappingStopwatchCo...
