The Ultimate Toughness, Now in Ring Form

This new “G-SHOCK Nano” is a miniaturized recreation of the iconic DW-5600 model, scaled down to approximately 1/10th of the original size. The most impressive achievement of this model is its ability to pack G-SHOCK’s core identity—its legendary shock-resistant structure and 20-bar water resistance—into the tiny form factor of a ring. The design achieves an incredible level of downsizing, with case dimensions of just 23.4mm x 20mm x 7.5mm (approx. 0.92″ x 0.79″ x 0.30″), making it about one-tenth the size of a standard G-SHOCK DW-5600UE.

The design faithfully inherits the most iconic “5600” square-shaped silhouette, which originates from the very first G-SHOCK model. The complex shapes of the bezel and band are recreated in meticulous detail using precision injection-molding technology. Furthermore, the buttons, buckle, and case back are crafted from stainless steel—the same material used in a standard G-SHOCK—to pursue an authentic, high-quality texture despite its miniature size.

The face features a 6-digit digital LCD, just like its 5600 inspiration. It is also packed with practical functions, including time display, calendar, LED backlight, stopwatch, and dual time. The band section utilizes the same pin-and-hole style as the classic resin models, allowing it to be freely adjusted to fit the wearer’s finger size.

The G-SHOCK Nano will be available in three symbolic colorways: black, red, and yellow. Each ring comes in a special presentation package that includes a G-logo-shaped display stand, making it an ideal specification for both collectors and as a gift.

Casio has released ring watches with time-telling functions in the past, which gathered significant buzz and popularity. The new DWN-5600, however, takes this concept a step further by instilling the very soul of G-SHOCK—its “toughness”—into a ring. This model can be seen as the perfect embodiment of the brand’s purpose: “the power to make surprise a part of everyday life.”
