G-SHOCK MASTER OF G – SEA / FROGMAN – Model GWFD1000BC-1

Overview

Professional gear built to challenge the limits of toughness. This FROGMAN from the MASTER OF G line features tan accents inspired by tactical equipment. Stripped of unnecessary decoration, the restrained color palette reinforces the line’s commitment to true utility.

The GWF-D1000BC uses those tan accents to striking effect in an otherwise all-black design. A DLC-coated bezel and black IP-treated front screws enhance the texture of the metal exterior, achieving a refined balance of quality and functionality.

The watch employs a composite band combining metal and bio-based resin for both strength and light weight. The band is extendable in two increments, so it can even be worn over a wetsuit.

Built for the water: ISO 200-meter water resistance for professional diving, a dedicated diving mode with depth measurement to 80 m, Triple Sensor (compass, thermometer, depth), Tough Solar power, and Multi Band 6 radio control.
