A newly developed miniature module and advanced metalworking technology have produced a new style of digital watch both practical and playful. This utterly distinctive watch expresses Casio uniqueness and originality and never compromises on even the smallest details. As a timepiece and as a piece of jewellery, this ring watch adds a touch of beauty to each and every moment.

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 mould. Using metal injection moulding (MIM), the case, case back, and ring are moulded 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). We downsized the standard watch module by a factor of 10 and combined it with a small button battery to create a 3-button digital watch that fits on your finger. Even at this small size, the watch features a 7-segment LCD that displays not only the time down to the second, but also the date, dual time, and stopwatch functionality. Pre-set the time of your choice, and the ring watch gives off a subtle, flashing light — not only handy for keeping time, but also a poetic nod to the fleeting twinkle of time.
