G-SHOCK 2100 Series – Model GA2100LXB-1A9

Overview

LUXE BLACK reinterprets the standard 2100 series through a lens of modern refinement. By eliminating excessive ornamentation and focusing on a disciplined sense of minimalism, the series pursues a timeless quality that does not fade with age.

Set against deep black tones, subtle contrasts emerge, using G-SHOCK toughness as a foundation for a product defined by quiet presence and controlled shine. The dial carries a matte black finish with a fine textured surface, lifted here by gold-tone accents.

The octagonal case uses a Carbon Core Guard structure with a carbon and bio-based resin bezel, keeping the whole watch to just 51 g while holding 200-meter water resistance.
