GMC-B2100AD-2AER

The first G-SHOCK chronograph, GMC-B2100AD-2A, made entirely of steel and with an octagonal case. 

A newcomer to the ever-evolving 2100 watch line.

This model pays homage to the past with its octagonal bezel and dimpled strap, inspired by the design of the original 1983 G-SHOCK, but revamped in stainless steel for its case, bezel and strap. Between the bezel and case, fine resin cushioning components ensure a shock-resistant structure with an all-metal finish.

The bezel, manufactured with a meticulous forging, cutting and polishing process, features a circular finish on the top and an elegant mirror polish on the slopes. In addition, delicate molding and vapor deposition, achieved through Casio's ultra-precise technology, add a touch of sophistication and quality to the indexes and rings of the inner dial.

The screw-down crown follows the octagonal design of the bezel, allowing the size of the case to be reduced without compromising G-SHOCK's characteristic shock resistance.

High-density mounting allows for a compact module with all the advanced features you enjoy, in a reduced profile that is comfortable to wear.

Equipped with Bluetooth®, it easily syncs with your smartphone to give you an always-accurate time indication. Plus, it features Tough Solar technology, a high-brightness LED light and a host of practical functions that perfectly balance and enhance your timekeeping experience.
