Casio G-Shock Small Classic Watch GM-S2100BC-1AER

Introducing the Casio G-Shock GM-S2100BC-1AER, the most elegant interpretation of the iconic GA-2100 designed specifically for the modern woman. This timepiece stands out with its sophisticated chromatic combination: an octagonal case in brilliant gold-tone finish that beautifully contrasts with the matte black resin strap. The silver dial features a radial texture that subtly reflects light, while the rectangular gold-tone indices and matching hands create perfect visual harmony. The small digital display at 6 o'clock integrates discreetly without breaking the ensemble's elegance.

At its heart beats the Casio module 5663, an analog-digital caliber offering perfectly balanced dual reading. Three main hands mark hours, minutes and seconds on the main dial, while the digital display shows complementary information like date, day of the week and second time zone. Functions include stopwatch with 1/100 second precision, countdown timer, world time with 31 time zones, 5 daily alarms, hourly signal and automatic calendar to year 2099. Double LED illumination ensures perfect reading of both hands and display in low light conditions.

This piece belongs to the G-Shock Small Classic collection, which adapts legendary G-Shock resistance to more refined proportions without compromising durability. Born in 1983 from engineer Kikuo Ibe's dream of creating an unbreakable watch, G-Shock revolutionized watchmaking with resistance tests from 10-meter heights. Today, four decades later, it remains synonymous with absolute toughness and avant-garde design.
