Casio GMCB2100ZE1A | G-SHOCK FULL METAL Black

Celebrate 50 years of Casio watches with a commemorative G-SHOCK timepiece that sparkles with Casio passion for new value and constant innovation. The GMC-B2100ZE embodies the spirit of craftsmanship inspired by the excitement of “making something from nothing” — the thrill of going from “0” to “1.” This G-SHOCK full-metal chronograph features a black and gold color scheme that evokes the first flicker of light, that spark of innovative craftsmanship, where the creation of new value begins. The single gold-color link on an otherwise black ion-plated band is a special touch that catches the eye, flickering like a light that breaks the darkness and illuminates the path to value innovation. The link is also laser engraved with “50th ANNIVERSARY.” As a special design touch, the outer perimeter of the dial is printed with 0’s and 1’s, capturing the Casio devotion to the art of making something from nothing. The screw-down crown is designed in the same octagonal shape as the bezel for a more compact timepiece with no sacrifice in outstanding G-SHOCK shock resistance. High-density mounting keeps the chronograph module slim, while still providing the advanced functions you love in a compact profile and comfortable fit.
