Casio introduced the bizarre-looking Ring Watch in late 2024, mirroring the design of a classic Casio wristwatch, but designed to be worn on your finger. The manufacturer is now taking this concept one step further with its new offering, featuring a similar retro timepiece design, but with all the attributes you’d expect from a modern-day smart ring.

The Japanese watchmaker has released the CRW-H001, which doesn’t look too dissimilar to the old Ring Watch. It even features a similar LCD panel that can show the time and set a stopwatch or alarms for you. However, as the Chinese product page reveals, this smart ring can do a lot more, including monitoring the wearer’s heart rate, blood oxygen level, and body temperature (via Gizmodo).
