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.
A Tribute to the CASIO Watchmaking Legacy
The CASIO Digital Ring Watch is more than just a stylish accessory; it’s a testament to 50 years of innovation. In celebrating CASIO's long legacy, this miniature timepiece takes the precision and functionality we associate with classic CASIO watches and delivers them in an entirely new form—a ring. This nod to the past is designed with a bold, forward-thinking twist that brings nostalgia together with cutting-edge advancements.
World innovator CASIO began with the yubiwa pipe
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 ring watch is a nod to this very first product using original ideas and technologies to create new value.
Tiny Engineering, Big Impact
One of the most impressive features of the CASIO Digital Ring Watch is its engineering excellence. It’s built on the foundations of miniaturisation and precision metal moulding, showcasing a commitment to pushing the boundaries of what’s possible in timepiece design.
Crafted entirely from metal, this ring beautifully captures the intricate details of a classic CASIO watch, all at a fraction of the size. The module powering the ring is roughly one-tenth the size of a standard wristwatch mechanism, demonstrating exceptional advances in miniaturisation. This tiny marvel still provides the full functionality of a digital watch, including three functional buttons and a 7-segment LCD display.
Precision Craftsmanship Meets Playful Design
CASIO has maintained the tough aesthetic that has become a trademark of its designs while incorporating cutting-edge technologies into this unique ring. The airtight construction is achieved through innovative glass bonding technology, which also ensures waterproofing, making the ring ready for daily use.
The design extends beyond its form, incorporating features like a flashing light that subtly illuminates your hand at pre-set times. It’s a small yet delightful feature that stays true to CASIO's commitment to adding a hint of fun to functional design.
Functionality Packed in a Compact Form
Despite its small size, this ring does not shy away from features. With time, date, dual time, stopwatch functionality, and more, it retains the practicality you’d expect from a CASIO watch. The 7-segment LCD display is easy to read, and the three buttons make navigating the features straightforward, preserving the intuitive experience that CASIO fans are accustomed to.
The CASIO Spirit: Celebrating 50 Years of Innovation
The launch of the CASIO Digital Ring Watch is not just a celebration of a product; it's a celebration of CASIO's spirit of exploration and ingenuity. Over the past five decades, CASIO has revolutionised the concept of wearable technology, and this latest piece is a shining example of how they continue to push the envelope. It’s a creative reimagining of CASIO’s legacy, delivered in a format that’s unlike anything we’ve seen before.
Whether you’re a longtime fan of CASIO or simply someone who appreciates exceptional design, the Digital Ring Watch is a conversation starter that takes a playful approach to celebrating half a century of watchmaking.
