Rescue Sport Watch for Outdoor Use

The Casio G-Shock G-7900-2D is a quartz digital watch built for men who need a tough, water-resistant instrument during water sports, rescue training or daily field work. Its resin case and band absorb shocks while the mineral crystal protects the display from scratches.

200-Metre Water Resistance and Timing Limits

The 200-metre rating covers recreational diving, surfing and high-velocity water impact. The 1/100-second stopwatch measures up to 99959 minutes 59.99 seconds, and the countdown timer handles long intervals, though neither function records split data beyond the stated maximum.

World Time and Calendar Constraints

World time covers 29 zones across 48 cities with a full auto-calendar running to 2099. Accuracy is rated at +/-15 seconds per month, so the watch will drift without periodic correction. The electro-luminescent backlight with auto switch and flash alert aids visibility, but there is no radio or satellite time synchronisation.

Questions about this item

Can I wear this 50 mm thick Resin case G-Shock alongside my older metal-cased watch without scratching it?

The Resin case and Mineral Crystal are softer than metal bezels, so storing or wearing them together may mark the G-Shock rather than the older watch.

How do I confirm the electro-luminescent backlight and auto light switch activate correctly after I set the watch?

Tilt the watch toward your face in darkness; the backlight should flash on automatically, and pressing the light button manually must also illuminate the digital display.

Does the box include the Resin band with buckle clasp fitted, or must I purchase the strap separately?

The Resin band with buckle clasp comes fitted to the 52.4 X 50 X 17.7 mm case; no separate strap purchase is required.
