Built for Active Women
The Casio G-SHOCK G-SQUAD GMD-B300-1 is a 43.80mm digital sports watch designed for women who track daily activity. A resin case and bio-based resin strap keep the profile light on the wrist. Quartz movement drives the black digital display with day and date readouts. Water resistance to 200m covers swimming and surface water sports.
Shock Resistant Everyday Wear
Mineral crystal protects the module from knocks while the fixed bezel holds the seal at depth. The buckle clasp secures the strap during high-intensity movement. No thermals, noise or power draw apply to a battery-powered quartz watch; the movement runs silently with no charging routine. Shock-resistant construction absorbs daily impacts without drift.
Step Tracking With Phone Sync
This model adds Bluetooth step counting and smartphone link so you can review trends without a dedicated fitness band. It replaces a basic digital watch when you want automatic activity logs and notifications on the same screen. The jump is worth it if you need 200m water resistance plus connected features in one compact resin package.

Questions about this item
How do I pair the GMD-B300-1 with my smartphone for step tracking?
Install the CASIO G-SHOCK Connected app, enable Bluetooth on your phone, then hold the watch's adjust button until the pairing screen appears; the step people miss is granting the app background location permission so sync continues when the phone sleeps.
What part of the GMD-B300-1 will need replacement first with daily wear?
The bio-based resin strap typically shows surface wear before the mineral crystal or resin case; CASIO stocks replacement straps in the same lug width for easy swap.
At what depth does the 200 m water-resistance limit of the GMD-B300-1 become a concern during prolonged swimming?
The 200 m rating covers recreational diving and extended surface swimming; the practical limit that appears first is the crown seal — always verify the buckle clasp is fully secured before submerging.
