Casio 50th Anniversary Ring Watch 25.2mm X 19.5mm Unisex

Ref. CRW-001G-9ER

A miniaturised digital watch built into a wearable ring, produced to mark Casio's 50th anniversary. The monocoque stainless steel case, finished with a gold ion-plated surface, measures 25.2 × 19.5 × 6.2 mm and weighs 16 grams. A mineral glass crystal sits over a six-digit, seven-segment LCD displaying hours, minutes, seconds, date, day, and a pm indicator. The module — roughly one-tenth the size of a standard Casio movement — runs on a single SR621SW cell and drives dual time, stopwatch, and an alarm that signals via a pulsing white LED rather than an audible tone. The ring fits a base inner diameter of 20 mm, with two included spacers reducing it to approximately 19 mm or 18 mm.
