Tudor Black Bay Ceramic One for Only Watch 2019

To support Only Watch charity auction, TUDOR introduces its first Black Bay model in ceramic. Entirely mat black, this unique looking watch is part of the long TUDOR diving watch tradition.

Since 1954, TUDOR has continuously improved its professional diving watches, which have been collaboratively developed with and used by pioneers of the field, including some of the largest navies in the world. It is in keeping with this heritage of both technical and aesthetic innovation that TUDOR has created the Black Bay Ceramic One – a unique matte black ceramic, titanium and stainless steel diving watch.

This model is 41 millimetres in diameter and is powered by the Manufacture Calibre MT5602, complete with a black PVD-coated rotor. It daringly boasts an all-black look, including dial and hands that are filled with black luminescent material as well as a hybrid rubber and matte alligator strap.
