Casio MIM Ring Watch

Creative and innovative Casio continues adding to its long list of “world-firsts.” It all began with the yubiwa (finger ring) pipe, developed at Kashio Seisakujo, the predecessor of Casio Computer Co., Ltd. That revolutionary ring hit the market in 1946, right after World War II, and was a big hit. The profits would later go toward the capital needed for development of a new kind of calculator. The same ring styling of the new Casio metal injection molding (MIM) ring watch is a nod to this very first product using original ideas and technologies to create new value.

Creating a ring-sized, full-metal version of the Casio watch’s complex form required the use of MIM. The case, case back, and ring are molded in one piece, with even the dimpled design on the band faithfully reproduced. A glass adhesive technique ensures a tight seal. The watch is built to be water-resistant while still allowing the battery to be replaced. The ring has an inner diameter of 20 mm and a circumference of 62.8 mm.
