Casio CRW-001 Ring Watch
The CRW-001 is a Casio watch in a stainless steel ring form and not a G-Shock, but we included it in the catalog since it is a tribute to the G-Shock DW-5000/5600 origin-based line and was Casio’s biggest hit of 2024. The CRW-001-1 is Casio’s first-ever functional ring watch and uses an all-new module that is 1/10 the size of a normal watch. Initially released in December 2024 for the Casio Watch 50th Anniversary (and still to be released in some countries in January 2025), it was originally believed to be a limited edition, but recent events, such as a reported upcoming restocking in Japan and the United States, suggest that more are being manufactured for a larger release. In addition to honoring G-Shock with its iconic shape, the ring watch harkens back to the first product from the business (Kashio Seisakujo) that preceded Casio, which was a ring pipe that held a cigarette.

Note: Although it is shaped like a G-Shock DW-5600, the Casio CRW-001 ring watch is not a G-Shock and does not have shock resistance or 200-meter water resistance. The CRW-001-1 is a functional digital watch with a stopwatch, LED backlight, and flash alerts for the hourly time signal and a daily flash time setting (but no sound alarm). The mineral glass display is attached with double-sided tape, and the battery is replaceable. The ring watch’s basic water resistance protects against splashes.
