Casio Ring Watch CRW001-1

We celebrate Casio Watch’s 50th anniversary by bringing back the very first ring watch. A whole new style of digital watch — both practical and playful — thanks to a miniature module and advanced metalworking technology. Creating a ring-sized, full-metal version of the Casio watch’s complex form is no easy feat. To make this possible, we needed to use a special method of metal processing to inject a mixture of fine metal powders and resin into a mold. Using metal injection molding (MIM), the case, case back, and ring are molded in one piece, with even the dimpled design on the band faithfully reproduced. A special glass adhesive technique ensures a tight seal for a watch built to be water-resistant while still allowing the battery to be replaced. With an inner diameter of 20 mm and a circumference of 62.8 mm, the ring fits a size 22 finger (US 10.5, EU U) and includes two size-adjusting spacers, in size 19 (19-mm inner diameter) and 16 (18-mm inner diameter). We downsized the standard watch module by a factor of 10 and combined it with a small button battery to create a 3-button digital watch that fits on your finger. Even at this small size, the watch features a 7-segment LCD that displays not only the time down to the second, but also the date, dual time, and stopwatch functionality. Preset the time of your choice, and the ring watch gives off a subtle, flashing light — not only handy for keeping time, but also a poetic nod to the fleeting twinkle of time. If you enjoy the look of the Casio Ring Watch, a similar G-SHOCK square watch will catch your eye: the DW5600E-1V is an iconic style that upon which G-SHOCK built its reputation. The silver metal G-SHOCK most resembling the Casio Ring Watch is the GMWB5000-1, with a stainless-steel metal bezel and Bluetooth® connectivity. For the full-metal experience that’s a stylistic dead ringer for the Casio Ring Watch, explore the practical elegance of the GMWB5000D-1, also with Bluetooth® connectivity. Like the G-SHOCK square all in black? Discover the dark charisma of the DW5600BB-1. Match your ring watch with the Casio square face of the W218HD-1AV, a silver metal Casio digital watch with 50 meter water resistance and LED light that compliments the CRW001-1 ring watch perfectly! A more simplistic style with necessary functionality, the Casio F91W-1 watch is both water resistant and reliable.
