Casio Ring Watch
- Stainless Steel Ring Watch
- Case size: 25.2 × 19.5 × 6.2 mm
- Approx. battery life: 2 years on SR621SW
- Water Resistant
- Mineral Glass
- SKU: CRW001-1
We celebrate Casio Watch’s 50th anniversary by bringing back the very first ring watch. 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.
