G-SHOCK GMB2100SD-1C

Casio G-SHOCK Full Metal 2100 Series – Model GMB2100SD-1C

The GMB2100SD-1C carries the G-SHOCK legacy into a bold new era — blending the octagonal 2100 Series design with the premium feel of full-metal stainless steel. Inspired by the original DW5000C’s classic dial colors, this watch delivers heritage style fused with modern durability, Bluetooth® connectivity, and solar-powered convenience.

Design Overview

This model faithfully reproduces the iconic G-SHOCK color codes:

• Red – passion for challenges

• Blue – symbol of superior water resistance

• Yellow – mark of outstanding shock protection

The stainless-steel bezel is crafted through an intensive forging, cutting, and polishing process. The flat surfaces feature a refined hairline finish, while the beveled edges are mirror-polished for maximum visual depth and texture.

Maintaining the original G-SHOCK’s legendary toughness, the GMB2100SD-1C incorporates fine resin buffering between bezel and case, a three-pronged lug system for secure band connection, and a screw-lock back for reliable water sealing. Stainless steel band links are dimpled to mimic the resin texture of the first G-SHOCK, honoring the model’s roots.

Produced at Yamagata Casio, the birthplace of G-SHOCK, this timepiece represents the full-circle evolution of Japanese precision and craftsmanship.
