Product Identity
The Casio G-Shock GMD-B300-4 is a women's sports watch with a 43.80 mm bio-based resin case and matching strap. It uses a quartz movement behind a mineral crystal and shows a pale pink digital dial. The watch is water-resistant to 200 metres and includes month, day and date display. It suits active users who want a lightweight, shock-resistant timepiece for daily wear and training.
Sustained Daily Use
Quartz movement delivers consistent timekeeping without the drift seen in mechanical watches over long periods. The fixed bezel and buckle clasp stay secure during repetitive motion such as running or swimming. Bio-based resin resists sweat and UV exposure better than conventional plastics, so the case and strap keep their shape and colour through months of outdoor activity. Smartphone link lets you sync settings without manual button sequences.
Thermals Noise Power
The watch runs on a standard button cell, so there is no charging cable, heat build-up or audible noise in normal use. Resin construction stays neutral against the skin in hot or cold conditions. Mineral crystal protects the display from scratches that would catch light and reduce legibility. Water resistance to 200 metres means the seals handle pool laps and open-water swims without condensation.

Questions about this item
How much power does the quartz movement draw during continuous daily use?
The quartz movement runs on a standard button cell with no charging required, so there is no daily power draw to manage.
What smartphone operating system is needed for the Bluetooth link to function?
The watch pairs with iOS and Android devices through the G-Shock Connected app for automatic time sync and activity logging.
Will the 43.80 mm case fit comfortably under a shirt cuff designed for slimmer watches?
At 43.80 mm the resin case sits higher than a dress watch, so a loose cuff or rolled sleeve works best.
