The Angelus U41 Tourbillon Skeleton's Dual Personality
The graphic structure of the movement equipping the Angelus U41 Tourbillon Skeleton characterizes its style. Enclosed in a 42mm titanium case, the U41 showcases its own architecture. Unfolding in a series of black and transparent seconds, this frame is both minimalist and graphic. Technical aspects merge with the aesthetic signature in an optimal combination of stability, design and ergonomics. The network of openworked plates and bridges thus forms and defines the very identity of the U41.
On the one hand, we have Angelus’ in-depth knowledge in designing and developing complication and skeleton calibers. On the other, the search for a committed style, accompanied by a comfortable and proportionate wearing experience on the wrist. The U41 is a sporty watch, as exemplified by its sculpted rubber strap, notched bezel, titanium case and movement designed in a metallic “mesh” format.
Angelus was seeking to create a light, yet sturdy watch. This pressing need for solidity requires a movement architecture that is capable of withstanding impacts and cushioning shocks without breaking or being deformed. A compromise between flexibility and rigidity. By enclosing all the main elements, including the wheels and the barrel, between two plates, the movement delivers maximum stability.
The A-300 caliber is a skeleton design and was developed as such. In order to strike the perfect balance between structural solidity and openwork detailing, Angelus opted for a “dual-beamed” plates and bridges design. The void that separates the two arms from these supporting elements is studded with jewels that accommodate the wheel axes. All of these components are treated with black ADLC to add contrast and texture.
Angelus movements frequently exhibit 90-hour autonomy, enabled by a balance oscillation speed of 3 Hz. For the A-300 caliber, the frequency has been set at 4 Hz for 60 hours of power reserve. This higher frequency safeguards the accuracy of the movement during impacts, and thus reduces its power reserve. This compromise is a natural continuation of the technical choices Angelus has made for the U41.
The U41 comes in two versions: one dressed in orange hues, and another in a range of blues illuminated by ashes of yellow on the minutes hand and minute circle. White Super-LumiNova coats the hours and minutes hands. The rubber straps work beautifully with the dominant colors.
Despite its technical intensity and sporty feel, the U41 remains reasonably sized: a 42mm diameter case with a thickness of 10mm. Angelus sought the perfect harmony between substance and form: the U41 delivers.
