Hands-On: The G-SHOCK Nano DWN5600 Ring Watch

The exterior case of the DWN5600 is made of the same bio-based resin that most modern G-SHOCKs are made of today, with an internal core made of glass fiber-reinforced resin. This past launch offered three familiar colors: black, red, and yellow. Dimensions are, well, small. The case measures 20mm, with a lug-to-lug (or is it knuckle-to-knuckle?) of 23.4mm. Its height of 7.5mm means it’s surprisingly comfortable to wear on the finger, sticking out far less than I had initially imagined from photos. 

While previous full-metal Casio ring watches were one size only, with two plastic spacers for smaller finger sizes, the G-SHOCK DWN5600 has a tiny, scaled-down version of the standard strap, with a metal tang buckle and all, making it the most versatile ring across finger sizes. The strap ranges from 48mm at its closest hole to 82mm, meaning any finger with a circumference of 1.89″ to 3.23″ can pull this one off.
