Roger Dubuis Excalibur Quatuor Full Silicon Case Watch

Since 2000, silicon has been used to make technical parts to improve the accuracy of the movement. Beyond technological limits and accepting incredible challenges is the brand’s eternal pursuit. Roger Dubuis adheres to this concept and launches the first all-silicon case watch in watchmaking history.

 With its unique lightness and hardness, silicon has become the only choice for the manufacture of special parts for watches. In fact, titanium is twice as light as steel, and silicon is twice as light as titanium, but its hardness is four times that of titanium. Its unique dark gray also makes this iconic work even more extraordinary. The atomic structure of silicon is similar to that of diamond, and its processing requires as much expertise as diamond processing. That’s why Roger Dubuis uses cutting-edge technology to create this precision timepiece in this ‘metal crystal’ material.

Balance spring, the soul of a mechanical watch

As the core component of mechanical watches, the balance spring has attracted much attention. This part controls the timing operation and thus determines the precise performance. At present, there are only a few watch factories capable of making other parts of the movement themselves, and homemade balance springs are even more valuable in the field of fine watchmaking. Roger Dubuis Roger Dubuis is one of the very few integrated watch factories capable of producing this key component completely autonomously. With this outstanding technology, the Geneva watchmaker ingeniously integrated four balance springs into the same movement to create the RD101 movement, which overcomes the technical difficulties that have so far been considered insurmountable.

Two major innovations to improve timing accuracy as

 The star product of the SIHH 2013 series, the Excalibur Quatuor watch, is released in a limited edition worldwide, expressing Roger Dubuis’ passion, boldness and creativity. Adhering to the tradition of watchmaking, this unparalleled watch condenses many technological innovations. Not only is it equipped with four balance springs, the power reserve display mechanism is also refreshing. These two outstanding technologies (patent pending) are not developed for research and development, but a testament to the relentless pursuit of precision in watchmaking.

 Due to gravity, as the wrist swings, the position of the watch changes continuously, which results in running errors. Although the tourbillon can partially solve this problem, Excalibur Quatuor offers a new solution. Excalibur Quatuor’s four balance springs work in pairs and are carefully laid out to immediately offset running errors caused by position changes. In other words, with the tourbillon canceling the gravity of the center for one minute, the Excalibur Quatuor can instantly cancel it.

Stunning 16 Hz frequency

 A traditional watch with a balance wheel with a frequency of 4 Hz can be regarded as a high-precision watch. The Excalibur Quatuor further breaks the limit of high-frequency vibration of the watch. hertz. 16 Hz is related to the basic movement, not just a function of the movement, which can be described as an extraordinary technical achievement. The four sets of balance springs swing 4 times per second, which doubles the vibration frequency of the Excalibur Quatuor 4 times, because all balances will not oscillate at the same time. This design provides a new guarantee for accurate timekeeping, replacing the ‘tick’ sound of traditional watches with a harmonious and gentle high-precision timing sound.

Novel and chic power reserve display

 Excalibur Quatuor watches not only challenge the laws of gravity and high vibration frequencies, but also read the power reserve in a unique way. The crescent-shaped dual display runs synchronously with the barrel, that is, 4.5 revolutions per day, and the hands rotate at a relatively slower speed. As the power reserve is depleted, the hands move with the barrel, so that the power reserve is accurately displayed on the two crescent arcs. This innovative mechanism is creative, precise, reliable, beautiful and intuitive. It is patent pending and is the perfect symbol of Roger Dubuis brand values.

3 + 2 = 5 differentials = 7 years of research and development = double innovation

In 2005, Roger Dubuis shocked the industry with a floating tourbillon watch equipped with a differential. Roger Dubuis has developed this Excalibur Quatuor with seven years of research and development. This masterpiece of timepieces brings together many extraordinary craftsmanship, not only integrating four balance wheels and novel power reserve display, but also equipped with five differentials. Three of them are connected to the balance wheel in the watch gear train, one on the central gear and the other two on the triple wheel, ensuring balance and achieving impeccable accuracy. The fourth differential guarantees a power reserve display, and the fifth connects the winding rod and two parallel barrels.

 Extraordinary mechanical mechanism combined with powerful design

 The Excalibur Quatuor is the creative work of Roger Dubuis, transcending the classic qualities that have established the brand’s legend. From the first draft of the design to the impressive appearance of the 2013 SIHH Geneva Watch Fair, this watch masterpiece embodies all the craftsmanship of the watch factory.

 Beyond technological limits and accepting incredible challenges is the eternal pursuit of the brand. Here, Roger Dubuis watchmaking team put pressure on the group to launch the first all-silicon case watch in the history of watchmaking. The technical complexity of this ‘metal crystal’ underscores Roger Dubuis’ outstanding craftsmanship and gives this watch masterpiece a unique aesthetic feature. This watch is available in 3 styles. Excalibur Quatuor is also available in rose gold, limited to 88 pieces.

 Watchmakers, engineers, and designers work hard at each design stage to achieve the perfect fusion of technology and design. Even trivial improvements are the result of careful and thorough consideration. The production of 590 parts of the RD101 movement also adheres to this criterion. The rigorous grasp of the design, production, adjustment and manual decoration of each component reflects the perfect combination of machinery and aesthetics. The beautifully laid-out dial elegantly presents four balances with hairsprings, which make people fascinated by cutting-edge watchmaking technology. The bridges and splints are extremely streamlined, giving a modern interpretation of the ancient hollow-out process. Excalibur Quatuor’s exquisitely crafted finishes exude unique beauty and charm. With a chic layout, bold design and powerful features, this modern fine watchmaking jewellery perfectly conveys the spirit of freedom and avant-garde of Roger Dubuis. To highlight the stunning mechanical construction of the watch, the case design incorporates the classic elements of the Excalibur series: rounded arcs, grooved bezels, crown protection and a three-pointer lug-fixed strap.

 Extreme quality is Roger Dubuis’s unswerving pursuit. The Excalibur Quatuor watch’s movement and the entire watch are engraved with the Geneva Seal, like all timepieces by Roger Dubuis, which is unique in the fine watchmaking world.
