CASIO CRW001-1D
CASIO CRW001‑1D Ring Watch — Digital Ring Timepiece
The CASIO CRW001‑1D Ring Watch is a playful yet practical mini digital watch worn on your finger, created to celebrate Casio’s 50th anniversary of making digital watches. Rather than a traditional wristwatch, this model miniaturizes Casio’s classic digital design into a fully functional ring‑sized timepiece crafted from stainless steel using advanced metal injection molding (MIM) technology.
Despite its tiny size, the CRW001‑1D includes essential digital functions such as timekeeping, dual time zone display, stopwatch, alarm/hourly alert, and calendar — all shown on a miniature 7‑segment LCD. With a stylish silver finish and functional digital module, it’s both a conversation piece and a wearable gadget for everyday use.
