Sports watch with bio-based resin case

The Casio G-Shock GBD-300-1 is a quartz sports watch built for daily training and outdoor use. Its case and strap are made from bio-based resin, reducing reliance on fossil-based plastics. A mineral crystal protects the black digital dial, and a buckle clasp secures the strap on the wrist.

200-metre water resistance for sustained immersion

Rated to 200 metres, the watch withstands prolonged pressure from swimming, snorkelling or heavy rain rather than brief splashes alone. Shock-resistant construction absorbs repeated impacts from sport and gym sessions. Quartz movement keeps time consistently through temperature shifts and vibration.

Digital display with smartphone link and calendar

The digital screen shows month, day and date alongside the time, and the watch pairs with a smartphone for data sync and notifications. Fixed bezel and 47.40 mm case thickness set the physical limits for wrist fit and under-cuff clearance. No analogue hands or mechanical complications are present.

Questions about this item

How much power does the quartz movement draw when the watch runs continuously?

The quartz movement is powered by a standard battery and does not require daily charging or an external power source.

What must I already own to use the smartphone link features?

You need a compatible smartphone with the G-Shock Connected app installed and Bluetooth enabled to pair with the watch.

Will the 47.40 mm case fit under the cuff of a dress shirt I already wear?

The 47.40 mm resin case is a standard G-Shock size that typically fits under most shirt cuffs, though fit depends on the specific cuff width.
