GMC-B2100Y-1AER

Sophisticated. Resilient. Full of character.

That's the GMC-B2100Y, an all-metal chronograph that pays homage to the first G-SHOCK from 1983, blending retro style with cutting-edge innovation.

Its octagonal bezel and dimpled strap evoke the original aesthetic, now reinterpreted with a stainless steel case, bezel and finishes for a more solid and modern look. To maintain the legendary G-SHOCK toughness, thin resin parts have been integrated between the case and bezel, achieving maximum protection without sacrificing metal.

The bezel, crafted through a careful process of forging, cutting and polishing, offers a spectacular finish: a brushed circular surface combined with mirror-like edges. On the dial, the high-precision indices shine thanks to a vapour deposition treatment that enhances their elegance.

The silicone strap provides comfort and durability, reinforced with a urethane film that improves wear resistance. On the underside, a gunmetal finish adds contrast and depth, harmonising with the metal body of the watch.

Inside, the GMC-B2100Y incorporates the latest technology:

Bluetooth® connection for automatic time adjustment from your smartphone.

Tough Solar with solar charging.

High-brightness LED illumination, among many other functions.
