Casio G-Shock Classic Watch GM-2100YMG-9AER

Introducing the Casio G-Shock GM-2100YMG-9AER, an extraordinary version of the iconic GA-2100 that elevates the concept of sports luxury to new heights. This model stands out for its impressive gold finish that completely covers the octagonal metalized resin case, creating a dramatic contrast with the matte black dial. Gold rectangular indices mark the hours with millimetric precision, while the gold-toned hands with luminous treatment guarantee perfect readability. The small analog subdial at 9 o'clock and digital display at 3 complete a balanced composition that breathes sophistication without sacrificing functionality.

At its heart beats the Casio 5611 module, an analog-digital caliber offering essential functions for daily use. The left subdial indicates days of the week, while the digital display shows date, second time zone and various functions. Among its capabilities are world time with 31 time zones, 1/100 second stopwatch with 24-hour capacity, countdown timer, 5 independent daily alarms, battery level indicator and automatic calendar until year 2099. Double LED illumination ensures perfect reading in any lighting condition.

The G-Shock collection was born in 1983 from engineer Kikuo Ibe's dream of creating an unbreakable watch. After more than 200 prototypes and drop tests from 10 meters high, a legend was born that has sold over 100 million units worldwide. The GA-2100 series represents the most elegant evolution of this philosophy, maintaining extreme resistance in a surprisingly refined and slim format of only 11.8 mm thick.
