The full-metal ring reworks Casio’s 1995 A168 as a tiny digital watch, favouring timekeeping over health tracking, apps and other smart-ring features.
Casio has returned to its ring-sized watch concept with the CRW-002, a metal miniature built around the company’s A168 digital watch from 1995. According to Casio’s announcement, the device is intended to behave like a conventional digital watch in a much smaller form, with timekeeping at its core rather than the layered functionality now common in many wearables. That makes the CRW-002 stand out not because it is packed with features, but because it is deliberately sparse.
The ring uses metal injection moulding to reproduce the watch’s shape in full-metal form, and Casio says the internal module is about one-tenth the size of a standard watch movement. Despite its scale, the CRW-002 still includes a six-digit LCD, three functional side buttons, an LED backlight, water resistance, a stopwatch, dual-time display, an auto-calendar and the option of 12- or 24-hour time. Casio also says the backlight can be set to pulse at specific times, including the top of each hour, preserving some of the practical quirks of a traditional digital watch.
Sizing is one of the clearest constraints. Casio’s Japanese product page says the ring is based on a standard size equivalent to US 10.5 and includes spacers for smaller fits. The company lists the model in silver and gold finishes, with the US announcement putting the prices at $135 and $155 respectively. Casio says the CRW-002 will reach selected retailers and its own website in November, alongside availability through the G-SHOCK Soho Store in the US.
The CRW-002 also fits into a broader effort by Casio to reinterpret familiar watch designs as jewellery-like objects rather than conventional wristwatches. The company previously released the CRW-001, another ring watch, and has also explored a more ambitious health-tracking format with the CRW-H001 in China, which adds connected functions and biometric monitoring. By comparison, the CRW-002 is almost defiantly plain. That restraint may be the point: in a market crowded with smart rings that quietly gather data and push users into companion apps, Casio is offering something much more literal and much less demanding , a watch that happens to wear on a finger.
