The second signature innovation for Rolex Daytona Replica is the Double Tourbillon with Differential Mechanism, a project that was born out of improving the chronometric performance of the single tourbillon. "Roger was really interested in increasing the performance of the tourbillon. This is important for me that people understand," says Bruttin. "Each time we pursued something, there was a strong horological rationale for it. We do not make watches simply for them to be visually entertaining. For Roger there always had to be a purpose. At first we tried by increasing the frequency of the balance wheel beyond 3Hz, but we were not achieving what we wanted. At this point we started to look at watches that feature two oscillators, with their results averaged out through a differential mechanism. So we looked at some watches, such as Philippe Dufour's Duality, which was the first wristwatch that used a differential to average out the errors from two oscillators. But Roger was also aware of some clocks that had been made at the Vallee de Joux's watchmaking school in the early 20th century, which also used this system of the differential. And so, we embarked on the journey of creating two flying tourbillons, where their results are averaged out by a differential mechanism. The differential, I can tell you, was one of the most challenging mechanisms to create in series. We were one of the first brands to ever use ceramic inside the movement, which we needed for some parts of the differential, but eventually we were able to make it work. Then from there, it seemed only natural to eventually make a skeleton version of this watch."replica watches
The Excalibur Spider Pirelli Double Flying Tourbillon
Andreatta says, "The Skeleton Double Tourbillon with Differential is an extraordinary watch -- I would say, one of the most recognisable in modern horology. I love that what is in essence the technical language of Rolex Daytona Replica, has also become the key aesthetic language of the brand. What we wanted to do was to use the platform of this icon to express different emotions. With the Excalibur Pirelli Ice Zero 2 and Excalibur Spider Pirelli Double Flying Tourbillon, the idea was to evoke all the codes of modern high-performance automobiles. The cases are crafted from Grade 5 titanium. The lugs of these cases are skeletonised both vertically and horizontally to create lightness, while the straps come from special tyres created by Pirelli -- in the case of the Ice Zero 2, the ones used for ice racing.
The gem-set Excalibur Superbia
"At the same time, the Double Tourbillon can be an incredible work of gem-setting metiers d'art, as with the Excalibur Superbia. The idea behind this watch is to take gem-setting to its most extreme. Our mindset was very similar to that of the incredible Japanese artist KAZ Shirane. We had to take 600 diamonds and sapphires cut in alternating triangular and tetrahedron shapes to create the visual effect we wanted and set them so that the setting is totally invisible -- not just the case,Rolex Air king Replica but also the crown and the buckle. We also gem-set the movement, specifically the bridges for the barrel that travel the full diameter of the movement.
"The Excalibur Twofold is a different animal as well -- more of a super-cool lifestyle watch, but with incredible technical credibility. It is an ultra-white watch, thanks to the mineral composite fibre (MCF) used for the case. The pure colour of this material is amazing, but it is also incredibly light -- much lighter than ceramic -- while remaining strong and resistant. For this watch, we wanted it to have an incredible light signature when clients wore it into a dark club, for example. And so, we had to create a new way to apply luminous material to the sloping, angular surfaces of the movement. As a gesture of pride that we were able to certify the movement with the Geneva Seal, we even made the seal luminous. Finally, we also created an all-new material to make the stitching on the strap luminous as well. This represents three patents, but for us, these innovations always go hand in hand with aesthetic audacity, and vice versa."
