A ring-sized watch of Casio Watches. A whole new style of digital watch  both practical and playful  thanks to a miniature module and advanced metalworking technology.
Creating a ring-sized, full-metal version of the Casio watch's complex form is no easy feat. To make this possible, we needed to use a special method of metal processing to inject a mixture of fine metal powders and resin into a mold. Using metal injection molding (MIM), the case, case back, and ring are molded in one piece, with even the dimpled design on the band faithfully reproduced. A special glass adhesive technique ensures a tight seal for a watch built to be water-resistant while still allowing the battery to be replaced. 
With an inner diameter of 20 mm and a circumference of 62.8 mm, the ring fits a size 22 finger (US 10.5, EU U) and includes two size-adjusting spacers, in size 19 (19-mm inner diameter) and 16 (18-mm inner diameter).
