TUDOR's latest diving watch, the Black Bay Ceramic One, is included in this year's Only Watch charity auction for research on Duchenne muscular dystrophy. The eighth edition of the biennial auction brings together one-off collaborations and original experiences, as 99 percent of the proceeds go to fund related research projects.

The Black Bay Ceramic One is entirely matte black, serving as TUDOR's first Black Bay model in ceramic. The titanium and stainless steel watch spans 41 millimeters in diameter and is powered by the Manufacture calibre MT5602, featuring a black PVD-coated rotor. The all-black look is made complete by the dial and hands that are filled with a black luminescent material, as well as the hybrid rubber and matte alligator strap. The PVD-treated steel case back of the Black Bay Ceramic One is then engraved with "PIECE UNIQUE" and "BLACK BAY CERAMIC ONE." Lastly, the watch is waterproof to 200 meters.
