Casio G-Shock GMA-P2100SA-1A1ER Classic Ladies Watch

The Casio G-Shock GMA-P2100SA-1A1ER is a modern women’s watch that impresses with its sporty look, rugged construction, and well-thought-out features. Both the case and strap are made from bio-based resin — a material derived from renewable resources that is not only durable but also meets environmentally conscious standards. The all-black design is accented with vibrant neon details inspired by modern sports gear, creating a bold and dynamic aesthetic. The hands and hour markers are color-matched and coated with phosphorescent paint, ensuring excellent readability even in the dark. With a case size of 46 × 40.2 mm and a weight of only 40 grams, the watch is comfortably lightweight while offering G-Shock’s signature shock resistance and toughness. It is water-resistant up to 20 bar, making it ideal for sports, leisure, or outdoor adventures. Technically, the watch delivers a wide range of features, including world time across 31 time zones, a 1/100-second stopwatch, a 24-hour countdown timer, five daily alarms, an hourly time signal, dual LED illumination for both the dial and display, and a fully automatic calendar valid until the year 2099. The analog-digital time display can be toggled between 12-hour and 24-hour formats, and the hand shift feature ensures an unobstructed view of the digital screen. With a battery life of approximately three years, the GMA-P2100SA-1A1ER is a reliable companion for everyday use.
