Roger Dubuis Excalibur Quatuor Dlc Coated Titanium Watch Appreciation

The ultimate challenge to gravity

 Excalibur Quatuor, as the name suggests, is the world’s first wristwatch equipped with four balance springs, which has extraordinary significance in the history of fine watchmaking. The whole mechanism is like four musicians, and a movement performed in conjunction with five differentiators at the same time, can be called the highest challenge to gravity. As one of Roger Dubuis’s finest examples of precision machinery in the 21st century, Excalibur Quatuor has once again surpassed the limit of precision and is a breakthrough in modern watchmaking.
After launching rose gold and silicon watches for the first time in the spring of 2013, the Excalibur Quatuor watch series introduced the new black DLC-coated titanium alloy watch for the first time at the 2013 WATCHES & WONDERS Watches and Miracles). This material is known for its strong modernity, elegance and durability, while combining lightness and solidity, giving this pioneering outfit with four balance springs, five differentials and two crescent-shaped power reserve display mechanisms. Sex watch is a brand new look with a sense of technology.

重大 A major innovation to improve timing accuracy

 The limited production of 188 Excalibur Quatuor DLC-coated titanium watches showcases Roger Dubuis’s boldness and creativity more than any other timepiece style. 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
(In patent application) R & D is not for research and development, but a testament to the relentless pursuit of watchmaking accuracy.

 Due to the effect of 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.

 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.

Stunning 16 Hz frequency

 A traditional watch with a balance wheel with a frequency of 4 Hz can be regarded as a high-precision timepiece. Excalibur Quatuor further breaks the limit of high-frequency vibration of this watch. This watch with four balance springs has a vibration frequency of 16 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 oscillate 4 times per second, correspondingly doubling the vibration frequency of the Excalibur Quatuor watch, 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 groups of 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 strong design sense

 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 DLC-coated titanium model that debuted at the WATCHES & WONDERS in 2013, this watch masterpiece combines all the expertise of Roger Dubuis.
Beyond the limits of technology and accepting incredible challenges is the eternal pursuit of the brand.

 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 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 watches are exquisitely crafted to 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: circular arcs, grooved bezels, crown protection and a three-pointer lug-fixed strap.

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

From Roger Dubuis to Gregory Bruttin: two generations of watchmakers fighting for the same dream

 Wisdom does not depend on age, so does talent, as long as there is sufficient will to constantly push the limits of watchmaking. This is exactly the case with Gregory Bruttin, the current head of movement development at Roger Dubuis. Fascinated by the beauty of machinery, the young watchmaker and his team created the Excalibur Quatuor. This is a dazzling bright sword move, but also heralds a wonderful chapter in the future of the watch factory.

 Gregory Bruttin has worked with several other well-known Swiss watch brands and achieved good results. He joined Roger Dubuis in 2002. Incorporating one of the most innovative watch factories in the 21st century from this point, it is even more significant that he was able to meet the founder of the watch factory, Mr. Roger Dubuis.

 Mr. Roger Dubuis is admired not only for his superb watchmaking skills, but also for his foresight and innovative spirit. The inspirational founder, when he founded the brand in 1995, positioned it as the only watchmaker to have all its movements certified for the Geneva Seal.

 Gregory Bruttin and Roger Dubuy have worked closely for many years, drawing on technology and creative inspiration from each other.
In 2006, a young watchmaker became the head of the brand’s technical department. He actively invested in the development of movements and participated in the establishment of the original watchmaking factory. In 2009, he led the movement research and development department and was officially appointed as the director of the movement research and development department in 2011.
Gregory Bruttin and Roger Dubuis are both endowed with the same genes: avant-garde spirit, excellent craftsmanship and talent, and jointly create a land of innovation. The common concept of the two naturally inherits the traditional value of the brand. With the launch of the Excalibur Quatuor, the watch factory launched a veritable star into the starry sky.

Hermes Arceau Pocket Millefiori Pocket Watch

The Arceau Pocket Millefiori pocket watch shows dazzling charm. Its crystal dial reproduces the scale pattern of crocodile skin in a breathtaking atmosphere. Echoing the case back that is adorned with this precious leather, it seems tempting to play a face-changing game. Is it true or false? Swim between illusion and reality.

   This production technique is derived from the Qianhua paperweight craft of the nineteenth century and is produced by Saint-Louis crystal workshop. The minerals, which have always been kept secret, are mixed to form a unique black substance due to chemical action, and then mixed into the molten crystal. Once removed from the furnace mouth, the crystal master uses blow molding technology to transform the molten material into crystal pellets.

   The craftsman pulled out the long fine crystal stems and cut them into small pieces. Finally, these long stems are used to combine the desired patterns. Is this animal scale or crystal pattern? This model is limited to two pieces, and in this dazzling time, you can experience the magic.
