A white-and-blue 2100 with a dial that comes alive after dark.

The GA-2100HDS-7A pairs the slim octagonal case with a blue phosphorescent dial inspired by bioluminescent water. The dial gives off a soft blue glow in darkness, while the double LED light keeps both the hands and digital display readable when you need a brighter view. The white case and band make this one of the cleaner, brighter takes on the 2100.

    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.
