Casio’s $120 CRW001-1 (AKA the Ring Watch) is back in stock on Casio’s website for the first time since it launched — then swiftly sold out — in December. The Ring Watch was released to commemorate the 50th anniversary of its original digital watch. While it may look like a novelty, the fully-functional watch impressed The Verge’s Victoria Song as both a fashion statement and a practical gadget. The silver ring has a sub-inch screen and comes in one ring size: 10.5. However, Casio includes 16 and 19 millimeter spacers to accommodate smaller fingers.

The Ring Watch’s LCD screen can display six digits, and be set to standard or military time. The three buttons around its face can start a stopwatch, display the date, or show the time in a different timezone. An alarm function will flash in the corner of its screen when the counter is complete.
