G Shock Duo Revival GA2100RL-1A Black/Resin

G-SHOCK GA2100RL-1A

A clean, stripped-back take on the GA2100, built with G-SHOCK’s trademark toughness. The octagonal bezel keeps things simple, while the original tri-colour accents — red, blue and yellow — nod to the brand’s core pillars: challenge, water resistance and shock protection.

Lightweight and durable thanks to the Carbon Core Guard structure and bio-based resin build, the GA2100RL-1A delivers everyday reliability with 200m water resistance, dual LED lighting and a 3-year battery. All the essential G-SHOCK functions are here: world time, stopwatch, countdown timer, 5 alarms and a full auto-calendar.
