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.
