Watches that are small enough to wear as rings on fingers are nothing new, but there is something deeply satisfying to every miniature version of a timekeeper that we originally love in its full size form for the wrist. Casio’s CRW-001 Ring Watch, which goes on sale on Boxing Day, is a perfect example as a shrunken version of a 5000 Series piece. It is being launched as a final launch in Casio’s anniversary celebrating 50 years of watchmaking.
Nothing is compromised in the ring. It is a water-resistant, rugged, full-metal digital watch with an LCD screen displaying hours, minutes, and seconds, along with calendar data, dual time zones, and stopwatch capabilities. It even has a backlight to make it readable in the dark, all running from a module that is 10-times smaller than a related wristwatch. The ring has an inner diameter of 20 mm (US size 10.5) and comes with two spacers to accommodate sizes 16 and 19.
