Baselworld 2017: Angelus Tourbillon Skeleton U21 & U22
From the movement to the case design, the objective from the get-go has been to showcase the splendor of the movement’s architecture and tourbillon while reducing as much weight as possible. For this purpose, the Angelus Tourbillon Skeleton feature a carbon fiber main plate, giving the impression of being a part of the case.
The Angelus Tourbillon Skeleton U21 interprets the uniquely structured movement in a noble metal case, combing the bezel-less carbon fiber central case element with polished and satin-brushed 18-karat red gold lugs, enhancing its visual appeal. The skeletonized bridges are solid 18-karat red gold for additional harmony between the case and movement. To further enhance legibility, the hands are filled with white SuperLumiNova.
The Angelus Tourbillon Skeleton U22 on the other hand features a carbon fiber and titanium case like the original U20, however with an even greater emphasis on weight reduction. Thanks to its carbon fiber main plate, the Angelus Tourbillon Skeleton U22 weighs a mere 54 grams in total. The flange ring has also been revisited, set with satin-finished applied indexes for the hour markers. The central hands offer a racy look thanks to the red SuperLumiNova.
The Angelus Tourbillon Skeleton even goes a step further. It does not boast an ordinary movement that has been skeletonized afterwards, but a tourbillon movement that has been created from scratch to be as open, three-dimensional and resplendent as possible.
The discerning eye will be pleased to discover that haute horlogerie has not been sacrificed on the altar of minimal mass: components have been hand-chamfered, hand-polished and hand satin-finished to ensure that they look as good as they are filigree.
And to further increase visibility into the top of the three-dimensional movement, both models features a unique design element. The case of the Angelus Tourbillon Skeleton is fashioned without a bezel and instead uses a sapphire crystal dome, which also allows a sideways view onto the movement.
The Angelus Tourbillon Skeleton U21 and U22 deserve closer inspection, which reveals many of the well-thought-out details that go into creating a contemporary, cutting-edge skeleton watch: the variable inertia balance wheel of the tourbillon is especially designed and crafted to minimize air friction; the patterned carbon fiber used in the main plate is offers maximum rigidity; ruby bearings are set into solid gold chatons. The ultra-light case, entirely made of carbon fiber, red gold or titanium and sapphire, has been designed to echo the three-dimensional aspect and the technical feel of the timepiece.
Special carbon fiber main plate
The carbon fiber used in the Angelus Tourbillon Skeleton U21 and U22 is very specific, offering the essential characteristics necessary for use in a haute horlogerie timepiece, with tolerances in the micron range. They are not decorative elements, but 100% functional.
