Description
Celebrate 50 years of Casio watches with a commemorative G-SHOCK timepiece that radiates Casio’s dedication to innovation and the pursuit of new value.

The GMC-B2100ZE captures the essence of craftsmanship, inspired by the excitement of creating something from nothing — the journey from “0” to “1.”

This full-metal G-SHOCK chronograph features a striking black and gold colour scheme, symbolizing the first spark of innovation and the beginning of new value creation.

A standout feature is the single gold link on the black ion-plated band, which gleams like a light breaking through darkness, illuminating the path to innovation. This link is engraved with “50th ANNIVERSARY” to mark the milestone. The outer edge of the dial is adorned with 0’s and 1’s, representing Casio’s commitment to the art of transforming nothing into something.

The screw-down crown mirrors the octagonal shape of the bezel, ensuring a compact design without compromising G-SHOCK’s legendary shock resistance.

With high-density mounting, the chronograph module remains slim while offering advanced functionality in a compact and comfortable profile.
