- Casio has transformed its classic A168 digital watch into a miniature, fully functional ring watch, complete with a stainless steel case and three-button controls.
- The new CRW-002 features a tiny LCD display, stopwatch, dual time, LED backlight and approximately two years of battery life.
- Two versions are available in Australia: the silver CRW002D-1A at AUD $249 and the gold CRW002G-9A at AUD $299.
Casio has spent decades proving that a good watch doesn’t need to be all that complicated. Now it seems they don’t even need to be on your wrist. The Japanese watchmaker has unveiled the CRW-002 Ring Watch, shrinking its iconic A168 into a fully functional timepiece small enough to wear on your finger.
It’s yet another ring watch in Casio’s finger-sized timekeeping lineup. The original CRW-001 was first revealed in 2024, followed by a miniature G-SHOCK, while Bandai recently decided it was a good idea to squeeze an entire Tamagotchi onto your finger. At this rate, we’ll run out of fingers before Japanese manufacturers run out of gadgets to put on them.
This time around, Casio has gone back to another of its most recognisable designs. First introduced in 1995, the A168’s familiar rectangular face, digital display and metal bracelet have all been miniaturised right down to the coloured lettering around the screen. And though it looks like something you’d find in a dollhouse, it’s still a working digital watch.
1/2Shrinking Down a Casio Icon
The CRW-002 measures just 25.2 x 18.2 x 6.2 mm and weighs 15 grams, making it slightly narrower and lighter than the original CRW-001 watch ring. Its stainless steel construction uses metal injection moulding (MIM), a process that allows Casio to reproduce the A168’s intricate case and bracelet design at a fraction of the size.
It’s all surprisingly faithful to the original, with a glossy case, matte-finished bracelet links that wrap around your finger and the familiar black dial surround. Inside, Casio has shrunk its standard digital watch module to approximately one-tenth its usual size. Somehow, there’s still room for a six-digit LCD displaying hours, minutes and seconds, alongside dual time, an automatic calendar, 12/24-hour timekeeping and a 1/100-second stopwatch. Yup, it’s a proper little digital watch, alright.
It even has three working buttons and a white LED backlight. Casio has also included its Time Flash function, which makes the display emit a subtle pulse of light on the hour or at a preset time. Whether you’ll actually notice it is another question, particularly since Casio warns that the light may be difficult to see in bright conditions.
The CRW-002 is water-resistant for everyday use, so maybe don’t take it swimming in the deep end. It also runs on a replaceable battery rated for approximately two years. Not bad for something that looks like it belongs on the world’s smallest wrist.

1/4Cost, Size and Australian Availability
Depending on how many fingers you have left, Casio is bringing two versions of the CRW-002 to Australia as part of the brand’s November 2026 collection: the silver CRW002D-1A for AUD $249 and the gold ion-plated CRW002G-9A for AUD $299.
As for sizing, there’s one important catch. Unlike a conventional watch bracelet, the ring itself cannot be adjusted. It comes in a Japanese size 22, equivalent to a US 10.5, with an internal diameter of 20 mm. Two included spacers reduce the fit to the equivalent of Japanese sizes 19 and 16, with internal diameters of 19 mm and 18 mm, respectively.
Each watch also arrives in a presentation box with a dedicated pouch and silicone display stand, presumably for those moments when your miniature Casio needs somewhere to rest.
