【Model Number】CRW-001G-9JR 【Condition】Brand new, unused 【Accessories】Price tag, dedicated box, instruction manual 【Release Date】October 17, 2025 【Retail Price】¥22,000 The Casio Ring Watch is a ring-shaped digital watch that recreates the functions and intricate design of Casio watches in a ring size, down to the smallest details. The stainless steel ring is formed with advanced metal injection molding technology to create fine details and is coated with gold-colored ion plating. The monocoque structure and glass bonding technology enhance airtightness, and while the battery can be replaced, it also achieves everyday water resistance, resulting in a design that combines practicality and playfulness. The small module is downsized to about 1/10 the size of a typical watch module, and combined with a small button battery, it realizes a digital watch with three buttons in a ring size. Furthermore, it is equipped with a 7-segment display LCD, which displays hours, minutes, seconds, as well as the date, dual time, stopwatch, and more. It also features an emotional flashing light function where the light gently blinks when the set time is reached. The ring size is size 22 (US: 10.5 / EU: U) with an inner diameter of 20mm and a finger circumference of 62.8mm. Two size adjustment spacers are included: size 19 (inner diameter 19mm) and size 16 (inner diameter 18mm).
