CASIO G-Shock GMA-S2100-7A 200m 43.00 mm Women's Watch

Compact diver's watch for active wear

The CASIO G-Shock GMA-S2100-7A is a 200m water-resistant watch built for women who need a tough, everyday timepiece. Its quartz movement drives both analog hands and a digital display, giving a clear readout of the time and date. The 43.00 mm resin case keeps the profile slim while retaining the brand's shock-resistant structure. White index markers on a white dial and Neobrite illumination support low-light legibility.

Resin construction with fixed bezel and buckle clasp

A resin case and matching strap resist sweat, salt water and daily knocks without adding weight. The fixed bezel removes a moving part that could snag or loosen during sport. Mineral crystal protects the dial from scratches better than acrylic. The buckle clasp secures the strap with a simple pinch action, so the watch stays put during swimming or high-intensity movement.

Quartz analog-digital hybrid limits

Quartz accuracy removes the need for daily winding, but the movement cannot be regulated by the wearer. The analog and digital displays share a single power source, so a dead battery stops both functions at once. Mineral crystal, while hard, can still shatter under a sharp impact that sapphire would survive. Buyers who want solar charging, atomic time sync or a screw-down crown will not find those features here.
