The U50 Diver Tourbillon Black Edition stands out with its uniquely structured manufacture skeleton movement and dark tones. While conceived with all the properties sought in a diver’s watch, the U50 Diver Tourbillon is high-performance timepiece. With its stealthy black silhouette, this limited edition blends into any situation.

Crafted in a 46mm-wide lightweight yet robust titanium case with a black DLC treatment all over, the U50 Diver Tourbillon features two large screw-down crowns. The two-position crown at 4 o’clock is used for winding and setting the time, while the crown at 2 o’clock is used to rotate the unidirectional 60-minute rotating bezel. Opposite, at the 9 o’clock position, a helium escape valve is placed to ensure the watch’s water resistance of 300 meters (1,000 feet), even during saturation diving so the helium molecules could not make their way into the case under pressure.
 

Instead of a solid dial, the U50 Diver Tourbillon features an open face with a dark but legible hours’ ring in grey, as well as white Super-Luminova on the indexes. Matching the dial, the hours, minutes and seconds’ hands are black plated and filled with Super-Luminova. Both face and case back crystals are made of antireflective sapphire.

The result of years of intensive R&D by Angelus’ engineers and watchmakers, the U50 Diver Tourbillon’s A-300 mechanical hand-wound caliber is designed as a skeleton from the ground up rather than simply being a cut-out version of an existing movement.
 

Much reduced in weight, it has maximum rigidity from its beam-type bridges and the fact that all the movement’s main elements, such as the wheels and barrel, are firmly secured between two plates. This design replaces the conventional main plate and bridges construction and massively increases the mechanical resistance of the movement. The watch’s rigidity is further enhanced by the Angelus in-house six-spoke design, which reinforces the wheel train and protects the skeletonized ratchet and barrel. Finally, the movement is entirely manufactured in-house.

With its core functions – hours, minutes, small seconds – the A-300 caliber has a 55-hour power reserve. The 4 Hz / 28,800 vph frequency is a guarantee for precision. Even though the caliber is intended as a high-performance, it has painstakingly executed with snailed black DLC coating and chamfered edges, matching the blacked-out allure of the U50 Diver Tourbillon Black Edition.

The U50 Diver Tourbillon Black Edition comes on a black rubber strap bearing the Angelus logo, with a Bback DLC titanium pin buckle, completing the look of this 25-piece limited edition diver’s watch.
