Casio G-Shock Nano DWN-5600-9ER Limited Edition ring watch

The new Casio DWN-5600-9ER Limited Edition is a miniature version of the legendary DW-5600 model – only about a tenth of the original size. This ring watch is an amazing technical feat that reproduces the details of the original G-SHOCK with incredible accuracy. The side buttons, buckle and LCD display are all made using advanced molding techniques, creating an authentic G-SHOCK feel on a micro scale.

Despite its compact size, the G-SHOCK Nano is shockproof and water resistant to 20 bar (200 m), making it as durable as a full-size G-SHOCK. The watch's battery is also replaceable. The display provides all the information you need: hours, minutes, seconds, dual time, stopwatch and auto calendar. The adjustable soft LED light flashes at the time of your choice, creating a subtle glow – a small but striking detail. The watch's bezel and strap are made from bio-resin, reflecting Casio's commitment to sustainability. Each G-SHOCK Nano comes in a special packaging with a silicone stand, making it perfect for both wearing and collecting.
