CASIO G-Shock GMA-P2100BB-1A Women's Watch

Compact Bio-Based Resin Design

The GMA-P2100BB-1A is a slim analog-digital G-Shock built for smaller wrists. Its case measures 46.2 x 40.2 mm with a thickness of 40.20 mm. The bezel and strap use bio-based resin sourced from renewable organic resources. A fixed bezel and mineral crystal complete the durable, all-black matte finish.

Quartz Movement Practical Limits

Quartz movement keeps time without winding but requires a battery change every few years. The module supports 12 and 24 hour formats plus a full auto-calendar pre-programmed until 2099. World time covers 31 zones across 48 cities with UTC offset. No radio-controlled or Bluetooth sync is included, so manual adjustment is needed for daylight-saving changes.

200M Water Resistance and Function Headroom

Rated to 200 m, the watch handles swimming, snorkelling and surface water sports comfortably. Shock-resistant construction absorbs daily impacts. The double LED Super Illuminator lights both analog and digital areas. Timing features include a 1/100-second stopwatch, countdown timer and 5 daily alarms with hourly signal. Buyers needing dive-log memory, GPS tracking or smart notifications will find those functions absent.
