The U50 Diver Tourbillon Black Edition is powered by the A-300 in-house tourbillon movement.
The A-300 in-house tourbillon movement was developed from the bottom up to enhance its three-dimensionality and sculptural beauty while boosting its performance and shock-resistance.
The U50 Diver Tourbillon Black Edition
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.
After entering the scene as a diver’s watch like no other, the Angelus U50 Diver Tourbillon returns in a bold black limited edition.
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-Luminovaon the indexes. Matching the dial, the hours, minutes and seconds’ hands are black plated and filled with Super-Luminova.
The result of no less than four years of intensive R&D, the U50 Diver Tourbillon’s A-300 caliber was 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 design is highly complex and features a variety of curves and lines combined with alternating polished and satin-finished surfaces and a see-through back.
With its core functions – hours, minutes, small seconds and one-minute flying tourbillon – the A-300 caliber has 23 jewels, a Swiss lever escapement and measures just 4.3 millimetres in thickness and 32.8 millimetres in diameter. The 4 Hz / 28,800 vph frequency is a guarantee for high performance and precision.
This impressive timepiece is secured to the wearer’s wrist by a black rubber strap bearing a three-dimensional motif and Angelus logo and fastened by a titanium pin buckle.
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 haute horlogerie finishing with snailed black ADLC coating and chamfered edges. The design is enhanced by a skeletonized ratchet and barrel in the exclusive Angelus six-spoke design.
