Angelus keeps with its tradition of utilizing technologically forward materials to manufacture highly complicated and aesthetically interesting timepieces. The House stretches the limit of its famous diving tourbillon movement, adding a 5-day power reserve to its list of features. While meeting the required diver’s watch criteria, the U51 Diver Tourbillon comes with high technical features. In fact, the A-310 calibre is dedicated to efficiency, with a silicon lever escapement and with all bridges as plates made of titanium. Furthermore, Angelus’ engineers and watchmakers pushed the boundaries with a remarkable 5- day power reserve while keeping the 28,800 vibrations per hour (4 Hz) frequency, ensuring a high precision. Finally, the tourbillon cage is set on a ball bearing instead of pivots to gain in stability. Even though the U51 Diver Tourbillon is intended as a high-performance sporty timepiece, the skeletonised movement has been carefully decorated with sandblasted finishing, enhancing the natural colour variations of the titanium.
