This is a limited edition of 25 pieces 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.
