Originally released in 2018, the Angelus U50 Diver Tourbillon was the brand’s first diver’s watch. With a high level of skeletonization of its movement allowing for maximum transparency and an incredible view of all of its components. Now, along with the release of the Angelus U50 Diver Tourbillon Black Edition comes the new Angelus U51 Diver Tourbillon 5-Day Power Reserve in a colorful combination of orange and stormy blue. The U51 Diver Tourbillon maintains the same proportions at 45 mm as its predecessor the U50 Diver, in a titanium case that has been slightly redesigned to differentiate it from its U50 siblings.
