Rated by Watch It clients

The MR-G MRG-B2100D-1A is the octagonal G-SHOCK distilled into finely finished metal. Its dark dial keeps attention on the angular titanium case and bracelet, while a multi-component bezel, incorporating a hard Cobarion alloy top, allows individual surfaces to be finished before assembly. The result is a restrained watch whose details reward a closer look.

Despite its sophisticated exterior, it remains a G-SHOCK: shock-resistant, water-resistant to 200 meters and powered by light. Radio-controlled time adjustment and Bluetooth connectivity make precise everyday timekeeping convenient. At 44.4 mm wide, it has a definite wrist presence without abandoning the instantly recognizable 2100 design.

Our Take

We like the dark dial against the bright titanium here. It puts the focus on the shape and metal finishing, making this the B2100 we'd show someone who loves the craftsmanship but doesn't want a colorful dial. That's what you're paying extra for.

    G-SHOCK, the watch that brought the new concept of toughness to the timepiece.
    It began with a reckless challenge to the conventional wisdom of the day, a developer’s belief that it was possible to construct a watch that wouldn’t break, even if dropped. Project Team Tough was formed to build it in 1981.
    The team created over 200 prototypes one after another over a period of about two years. They finally arrived at a shock-resistant structure. This marked the birth of a technology that is tough to the core.
    And G-SHOCK has continued its unceasing evolution ever since, in pursuit of greater toughness in every respect, from structure and materials to functions. Today, the development team’s passion for challenge and constant efforts have reached fruition in Triple G Resist, a structure with the strength to withstand 3 types of gravitational acceleration.
