The G-Shock GW7900B-1 is a solar-powered, atomic-synced rescue watch with tide graph, moon data, and 200m water resistance. Part of the iconic G-Rescue series with oversized case and glove-friendly buttons.

G-Shock GW7900B-1: Solar Atomic Rescue Series

The G-Shock GW7900B-1 is part of the legendary G-Rescue series, built for harsh environments and outdoor adventures. This tough solar-powered watch automatically syncs its time via Multi Band 6 radio signals from six transmitters worldwide, ensuring atomic accuracy without any manual adjustments.

Tide and Moon Data

Purpose-built for coastal activities, the GW7900B-1 features a tide graph that displays tide levels for any specific date and time, plus moon phase data showing moon age and phase graphs. Whether you’re surfing, fishing, kayaking, or planning a beach day, these tools help you work with nature’s rhythms.

Tough Solar Power

The Tough Solar charging system converts any light source into power, delivering approximately 9 months of operation on a full charge even without additional light exposure. A power saving mode extends standby time to 26 months by blanking the display when stored in darkness. The battery level indicator keeps you informed of remaining charge.

Built for the Elements

The oversized 50mm resin case with four-point protection design handles extreme impacts, while 200-meter water resistance makes it suitable for serious water activities. The large buttons are designed for operation while wearing gloves. World time covering 31 time zones, a 1/100-second stopwatch, countdown timer, and five daily alarms round out the comprehensive feature set.
