Casio CRW-001-1: The ring watch that redefines the codes of watchmaking

To mark its ^50th anniversary, Casio has made a splash by unveiling the CRW-001-1 , a digital watch in a unique format. Designed to be worn on the finger like a ring, this unique creation combines extreme miniaturization, technological innovation, and a nod to the brand's history. A futuristic object that fascinates collectors and fans of cutting-edge design alike.

A tribute to the origins of Casio

This exceptional model owes nothing to chance. It is inspired by the very first product marketed by Casio in 1946: the yubiwa pipe , a ring-shaped cigarette holder. With the CRW-001-1, Casio comes full circle, returning to this ring format but integrating all its expertise in digital watchmaking. The result is stunning: an ultra-compact, readable and functional watch, to be worn like a piece of science fiction jewelry.

A unique format, a perfectly mastered design

The CRW-001-1 takes the iconic square silhouette of the G-SHOCK DW-5600 models, miniaturized to fit a finger. Using metal injection molding ( MIM ) technology, Casio has designed a one-piece stainless steel case where the case back, bezel and dial are all made from a single piece. This process ensures a neat finish, good water resistance and remarkable robustness despite the compactness of the whole.

A real watch, despite its miniature size

With its dimensions of 25.2 x 19.5 x 6.2 mm and a featherweight of 16 g, the CRW-001-1 incorporates a 6-digit LCD screen with LED backlighting. It offers:

the time (12h/24h format),
the date and day,
a second time zone,
a ¹ /100th of a second stopwatch,
a fixed-time flash light function.

It operates on an SR621SW button battery, providing approximately two years of battery life, and is splash-proof (not submersible).

A technological gem that is already a collector's item

Launched in December 2024 in Japan for around $120, the CRW-001-1 sold out immediately upon its release. International sales followed at a frantic pace, leading to stock shortages and queues on online stores. Today, the model is already considered a rare item, whose value continues to climb on the resale market.

The watch comes with two resin adjustment rings, allowing you to easily go from size 22 (equivalent to US 10.5) to a size 19 or 16, depending on the chosen finger. A simple and effective system for adapting this technological jewel to most users.

It appeals to technology fans, lovers of alternative design, and anyone looking for a watch unlike any other.
