Product Details
Description
The Casio G-SHOCK GM-2100LXB-1A9ER is part of the exclusive Luxe Black collection, reimagining the iconic 2100 series through contemporary minimalism. The case pairs a black ion-plated stainless steel metal bezel with a bio-based resin band, giving the watch a calm, refined presence. The dial impresses with a matte black surface featuring a fine texture that suppresses reflections and absorbs light. Newly developed slim hour and minute hands with elongated proportions, along with redesigned vapour-deposited hour markers, balance legibility with premium material quality. Gold accents on the inset dials and a vapour-deposit finish around the glass edge add depth and distinction.
The GM-2100LXB-1A9ER is water-resistant to 20 BAR and offers a wide range of practical functions: world time across 31 time zones, 1/100-second stopwatch, countdown timer, five daily alarms, and Neobrite luminous coating for readability in the dark. The auto-calendar is accurate through 2099. Weighing 72 g with case dimensions of 49.3 × 44.4 × 11.8 mm, the watch is built tough yet designed with purpose.
