G-Shock 50th Anniversary Ring Watch Quartz – CRW001-1

To celebrate its 50th anniversary, Casio proudly reintroduces a groundbreaking design: the Casio Ring Watch. Inspired by the original model, this full-metal, ring-sized digital timepiece blends innovation and nostalgia, offering both playful charm and practical functionality. Thanks to advanced metal injection molding (MIM) technology, Casio has faithfully recreated the original watch’s complex shape in miniature—right down to the signature dimpled band—while ensuring water resistance and durability through a specialized glass adhesive technique.

With a 20 mm inner diameter and a 62.8 mm circumference, the ring fits a size 22 finger (US 10.5, EU U), and includes two size-adjusting spacers for versatile wear. Inside, Casio has miniaturized its standard module by a factor of 10, resulting in a 3-button digital watch that fits comfortably on your finger. Despite its size, it delivers full digital functionality including a 7-segment LCD, dual time, date, stopwatch, and an LED backlight. A charming Time Flash feature offers a subtle twinkle at preset times—a poetic nod to the fleeting nature of time.

For those who admire the Casio Ring Watch, Casio also offers complementary square-faced models such as the DW5600E-1V, GMWB5000-1, GMWB5000D-1, DW5600BB-1, and the silver-toned W218HD-1AV. Each model echoes the ring watch’s sleek appeal with additional features like Bluetooth® connectivity and enhanced water resistance. For timeless minimalism, the F91W-1 offers classic Casio reliability in a simple, functional design. The Ring Watch isn’t just a celebration of Casio’s legacy—it’s a bold reimagination of what a timepiece can be.
