Casio GMA-S2100MD-1AER Women's G-Shock Classic Black • Rose Gold Dial • 20 bar Water-Resistant

The Casio G-Shock GMA-S2100MD-1AER is a compact women's watch from the GMA-S2100 series, presenting itself as a smaller, octagonal interpretation of the legendary GA-2100. The matte resin case in understated black tones is enhanced by a rose gold vapour-deposited dial with clean baton indices — a minimalist yet glamorous statement for any outfit. Both the case and the resin strap are crafted from matte urethane, making the watch pleasantly light on the wrist. The Carbon Core Guard structure inside delivers the shock-resistant toughness G-Shock is known for, while water resistance to 20 bar ensures outstanding everyday reliability.

The watch combines analogue and digital reading: two analogue hands for hours and minutes, plus a digital display showing seconds, date, month and additional functions. Features include world time across 31 time zones, a 1/100-second stopwatch, a countdown timer, five daily alarms and an hourly time signal. The dual LED illumination (Super Illuminator) guarantees excellent legibility even in the dark. Two SR726W batteries power the watch reliably for several years.
