Casio CRW-001 is a digital watch reduced to the size of a ring. Instead of a smart ring that measures health information, a small watch is placed on the finger.

Raise your hand and look at the time. It's a familiar movement, but the gaze passes over the wrist and stops on the fingers. There are numbers floating on a small metal ring, and next to it there is even a button like you would see on a digital watch. Casio's CRW-001 is a ring that resembles a wristwatch, but it is actually a working watch.
This product was first released in December 2024. When it comes to ring-shaped devices, it's easy to think of a smart ring that records sleep or exercise, but time is at the center of this device. The time is displayed on a small LCD screen and calendar, dual time, and stopwatch functions are included.
What it takes to make it smaller
Printing a watch face on a ring would not produce the same object. A device to display numbers, a battery, and a button to press must all be contained within a narrow body. Casio explains that it has miniaturized the existing watch module with high-density packaging and a small battery.
The metal body used a method of mixing metal powder and resin and forming it. Even the part that looks like a wristwatch band was engraved on the surface of the ring, leaving the familiar impression of a digital watch even though its size was reduced.
The fit matters as much as the functions
Since it is an item worn on the finger, the wearing conditions are as important as the function. The official guide gives the basic inside diameter as 20mm and describes two types of adjustment parts to fit smaller fingers. It is different from a freely adjustable ring that fits everyone.
Reading the screen or pressing buttons will not be the same as with a wristwatch. This is not a product that eliminates the inconveniences caused by its small size. Instead, it brings the shape of a clock seen from afar closer to your fingertips.
A small tool returns to the finger
Casio introduces this watch and also brings out a ring-shaped cigarette holder from the early days of its business. The rings of the past, which were used to hold cigarettes, and the rings of today that mark the time have different purposes, but they are connected in the form of placing a small tool on one's finger.
A phone could display the time much larger, yet this design deliberately puts it on a tiny ring. Rather than increasing the list of functions, the joy that comes from changing the size and location of familiar objects remains in your fingers.
