Casio is expanding its retro ring watch lineup with two new variants, the CRW-002D-1A and CRW-002G-9A. Both models bring the classic A168 digital watch design into a miniature ring-sized form factor.

Design Details

Despite their tiny dimensions, they retain traditional timekeeping features, including a seven-segment LCD, an auto-calendar, a 1/100-second stopwatch, and dual-time functionality.

The hardware is constructed from stainless steel using a metal injection molding (MIM) process, which blends fine metal powders with resin to form the intricate case and band details. Both models feature a matte-finished band contrasted with a glossy case, mineral glass over the display, and basic water resistance for daily wear.

Casio has also included the Time Flash function that uses a white LED to pulse at a designated time or on the hour. It’s a purely cosmetic addition that might not show up well in bright lighting. For power, the ring relies on a standard SR621SW watch battery that lasts around two years and can be easily swapped out when it dies.

Sizing is fixed to a single base size. The ring has a 20mm inner diameter, which is a US size 10.5 (size 22 in Japan). To fit smaller fingers, Casio includes two physical spacers in the box that adjust the fit down to Japanese sizes 19 or 16.

Pricing and Availability

The silver CRW-002D-1A costs $135 in the US and ¥19,800 in Japan. The gold CRW-002G-9A is priced at $155 in the US and ¥22,000 in Japan. Both versions are expected to be available in the US later this month. In Japan, the initial release is being handled through an online lottery application system.

In related news, Casio brings its premium A1000SP-7 stainless steel digital watch to Japan, while also launching three affordable LF-40W digital watches with a quirky retro-tech display.
