Product Description
The G-Shock GM-2100CL-5A continues Casio’s popular “CasiOak” series, recognized for its slim octagonal bezel and modern analog-digital hybrid display. This model stands out with its copper-colored ion-plated stainless steel bezel, forged and meticulously finished to emphasize its industrial geometry, paired with a warm brown fabric band that enhances its utilitarian appeal.
Housed in a 44.4mm case with a resin inner core for shock absorption, the GM-2100CL-5A delivers the lightweight toughness G-Shock is known for, while elevating its visual presence through the contrasting metallic bezel and rugged textile strap. The dial features a deep brown colorway with a minimalist layout, anchored by bold, luminous baton hour markers and hands for easy readability in low-light conditions.
This model offers a full suite of G-Shock performance features, including 200-meter water resistance, world time across 31 zones, a 1/100-second stopwatch, countdown timer, five daily alarms, and full auto-calendar pre-programmed until 2099. Power comes from a reliable quartz movement with approximately three years of battery life on CR2016.
Balancing the raw toughness of G-Shock engineering with refined metal detailing, the GM-2100CL-5A positions itself as both a functional everyday companion and a statement piece within the “CasiOak” lineage, appreciated for its blend of modern design and iconic G-Shock resilience.
