Casio G-Shock GMA-P2100SA-1A1ER
Product Information
Overview
The Casio GMA-P2100SA-1A1ER delivers a clean, all-black ana-digi profile in a compact 40mm format. Beneath the mineral glass, the 5730 module provides a quick overview with analog time, digital time, date, day and 24-hour display. LED light ensures readability in the dark, and 20 ATM and a resin case make the watch ready for everyday life, training and water. Stopwatch, split time, timer and perpetual calendar cover everything from intervals to travel plans.
Comfort
At 11mm tall, 46mm lug-to-lug and a light 40g, the watch sits firmly on your wrist without weighing you down. The flexible 20mm resin strap follows your skin and can be quickly adjusted with a buckle up to 19cm. The smooth case back and soft edges reduce pressure points, so the model slides easily under your sleeves and is comfortable to wear all day long – from gym sessions to commutes and weekend getaways.
Summary
The result is a versatile ana-digi that combines quartz precision and low weight with high durability. 20 ATM, mineral glass and resin protect in all weathers, while LED lighting, calendar, stopwatch and timer make everyday life easier. The all-black aesthetic is easy to match and stays discreet under the cuff. A reliable everyday watch that can withstand pace, water and shock.
