Tudor Black Bay GMT One 7983/001U

Tudor gave the steel case and bracelet a black coating and then tumble-polished them so that it wore off partially and at random. The 24-hour bezel and the date wheel are aged too, around a domed matte black dial. Instead of the Pepsi bezel of the regular Black Bay GMT 79830RB, the bezel insert is aged steel with engraved markings.

Inside is the automatic calibre MT5652-1U, the standard MT5652 upgraded to METAS-certified Master Chronometer, with a 70-hour power reserve and a patinated movement visible through a sapphire case back. The case is 14.6 mm thick and water-resistant to 200 m, the bracelet is riveted, and the 22 mm lug width means a 22 mm strap. The watch went to the Only Watch auction held by Christie's on 6 November 2021. Tudor's earlier Only Watch piece was the Black Bay One 7923/001 of 2015, with a black bezel and red triangle.
