Casio G-Shock Classic Watch GM-B2100SD-1AER

Introducing the Casio G-Shock GM-B2100SD-1AER, the most sophisticated evolution of the iconic GA-2100. This premium version stands out with its octagonal stainless steel case featuring a polished metallic finish that reflects light spectacularly, contrasting beautifully with the deep black dial. The metallic rectangular indices and silver hands with luminous treatment ensure perfect readability, while the small digital display at 3 o'clock shows complementary information with total clarity.

At its heart beats the Casio module 5691, a cutting-edge analog-digital caliber that incorporates Bluetooth technology for smartphone connectivity via the G-Shock Connected app. The Tough Solar system ensures continuous power through light absorption, while the Multi Band 6 function automatically synchronizes time via radio waves. Features include world time with 31 time zones, 1/100-second stopwatch with 1000-hour capacity, countdown timer, 5 daily alarms, and automatic calendar until the year 2099.

The G-Shock collection was born in 1983 with the vision of creating the unbreakable watch. After more than 200 prototypes and drop tests from 10 meters high, Kikuo Ibe successfully developed the triple protection structure that defines these timepieces. Four decades later, G-Shock remains synonymous with extreme resistance, technological innovation, and avant-garde design.
