Introducing the G-SHOCK nano, a miniature, finger-fit re-creation of the iconic DW-5600 at about one-tenth the size. 

Delivering impressive detail — from side buttons, to buckle to LCD, all precisely reproduced using advanced molding techniques in a form so compact it comfortably fits on your finger. 

Shock resistant and water resistant up to 20 bar, this ring-sized watch performs with the toughness of a full-on G-SHOCK,while still allowing the battery to be replaced.

Even at this small size, the LCD presents all the info you need — hours, minutes, and seconds, as well as dual time, stopwatch, and auto calendar. A soft, flashing light activates at your chosen time, adding a subtle and emotive glow. 

The bezel and band are made with bio-based resin, reflecting a commitment to environmental sustainability. 

Choose your favorite of the three most popular colors in DW-5600 history — black, yellow, or red. 

Each G-SHOCK nano comes in a special package with a dedicated silicone stand, for a timepiece that’s infinitely wearable and collectible.
