A modern, minimalist reinterpretation of the iconic 1983 G-SHOCK silhouette, the GMC-2500D-1A brings full-analog sophistication to the G-STEEL lineup. Crafted with a sleek octagonal stainless steel bezel and matching solid stainless steel bracelet, this timepiece transitions effortlessly from everyday casual wear to sharp office attire—all without sacrificing legendary G-SHOCK toughness.

Refined Analog Design
The clean, two-eye brass dial in deep black balances precision with restraint. A dedicated small seconds subdial sits alongside a distinctive fan-shaped three-cell date window, while a convenient hand-shift function moves the hands out of the way for an unobstructed view of your subdials. Finished with Neobrite luminous hands and indices plus a warm amber LED backlight, the dial stays legible day or night.

Engineered for Impact
Inside its slim 12.9 mm profile lies a lightweight resin and bio-based resin inner core engineered to absorb heavy shocks. Equipped with Casio’s Shock Release Hand technology, the minute hand uses a magnetic holding structure to dissipate impact energy and automatically return to the proper position if jarred—delivering true G-SHOCK durability in a refined analog format.
