CASIO CRW-001-1JR Men's Analog Watch - Stainless Steel Band
| Product Overview | |
| Introducing Casio's first ring watch. Through the development of a super compact module and advanced metal molding technology, we have created a new style of digital watch that combines practicality and playfulness. To achieve the complex shapes of Casio watches in a ring-sized full metal design, we adopted MIM (Metal Injection Molding) technology, which injects powdered metal. The case, back cover, and ring part are integrally molded, accurately reproducing even the band holes. Furthermore, airtightness is ensured through glass bonding technology. While it has a structure that allows for battery replacement, it also achieves water resistance for everyday use. The ring size is 22 (US: 10.5/EU: U) with an inner diameter of 20mm and a finger circumference of 62.8mm. Two sizes of spacers for size adjustment are included: one for size 19 (inner diameter 19mm) and one for size 16 (inner diameter 18mm). Compared to typical wristwatch modules, it has been downsized to about 1/10. By combining it with a small button battery, we have realized a digital watch with three buttons in a ring size. Additionally, it is equipped with a 7-segment display LCD. It displays not only hours, minutes, and seconds but also date, dual time, and stopwatch functions. When the time flashing light function is turned on, it gently blinks at the set time and every hour, expressing the sparkle of time emotionally. The special package also includes an original drawstring bag. 【The Origin of Casio Creating the World's First Ring Pipe】 With creativity and innovation, Casio continues to produce numerous "world's firsts." Its starting point was the "ring pipe" developed at Kashio Seisakusho, the predecessor of Casio Computer. It was released shortly after World War II in 1946 and became a huge hit during a time of material shortages. The profits from the ring pipe contributed to the funding of later computer development. The newly launched Casio ring watch also follows the ring style. It embodies Casio's commitment to creating new value through unique ideas and technology. | |
