Into the deep, dark infinite with the Angelus U50 Diver Tourbillon Black Edition

After entering the scene last year as a diver’s watch like no other, the Angelus U50 Diver Tourbillon returns in a bold black 25-piece limited edition.

A new reference from Angelus’ first diver’s watch collection, the U50 Diver Tourbillon Black Edition stands out from other diver’s watches 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 above all a sporty-chic, high-performance timepiece, able to withstand all kinds of physical activities – above and below sea level. With its stealthy black silhouette, this Black Edition blends into any situation.

Crafted in a 45mm-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 uni-directional 60-minute interior rotating bezel, in lieu of the exterior rotating bezel commonly found in diver’s watches.

Opposite the crowns on the left side of the case 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 where the watch would be exposed to helium gas that could make its way into the case under pressure.

Instead of a solid dial, the U50 Diver Tourbillon features an open display with a dark but legible flange ring, providing a subtle contrast between black and grey tones, as well as white Superluminova on the indexes. Matching the legible flange ring, the three hands are black plated and also filled with Superluminova. 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 then 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. 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 high performance and precision.

Even though the A-300 caliber in the U50 Diver Tourbillon is intended as a high-performance movement ready to take on more extreme situations, the ultra-slim movement has painstakingly executed contemporary high-end finishing with snailed black PVD 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 “A” logo, with a Black DLC titanium pin buckle, completing the all-black look of this 25-piece limited edition diver’s watch.
