Casio celebrates its 50th anniversary with the CRW-001-1JR ring watch, which offers a digital ring watch instead of the analog ring watches that started to attract interest in the late 90s and early 2000s. This way, it appeals to the feeling of nostalgia and adds its own touch to this concept. 

The CRW-001-1JR looks like a miniature all-metal version of the digital models in Casio's G-SHOCK and ICONIC series. It is made using advanced MIM (Metal Injection Molding) technology. This technology, based on powdered metal injection, allows Casio to reduce the complex shape of their watches to the size of a ring.

As you might expect, the stainless steel ring watch is waterproof. It can display the time in two different time zones simultaneously. The 7-section LCD displays the hour, minute, second, date, dual time, and stopwatch values. Thanks to the backlight, it can also be used comfortably in dark environments. The watch alarm notifies the user with a flashing light.
