Casio has introduced a new ring watch created in partnership with Colombian reggaeton artist J Balvin.
The CRW001JB-9 model transforms the brand's classic digital watch into a wearable finger accessory.

The device is not a smart ring. It lacks health sensors, step tracking, Bluetooth, or companion apps.
Instead, it functions purely as a miniature digital watch.
Design and Features
The stainless steel case features a gold ion-plated finish with a textured brick pattern around the display. Small rhinestones are set into the top and bottom bezels.
The back of the case is engraved with Balvin's signature flower logo.

The ring arrives in custom packaging that matches the gold brick texture of the hardware.
It measures 25.2 by 19.5 by 6.2 millimeters and weighs 16 grams.
Despite its small size, the watch includes standard digital functions. Users get a 1/100-second stopwatch, dual time, an auto-calendar, and a white LED backlight.
It runs on a standard SR621SW watch battery, which Casio estimates will last about two years.

The ring is manufactured at a single fixed size: US 10.5, with an inner diameter of 20mm.
To accommodate smaller fingers, Casio includes two physical spacers that reduce the inner diameter to 19mm or 18mm.
If your finger does not match one of these three measurements, the ring will not fit comfortably.
The CRW001JB-9 is priced at $200. Pre-orders begin on May 28, 2026, with a general release scheduled for June 4.
