Tudor Black Bay GMT One Master Chronometer for Only Watch 2021

TUDOR announces the Black Bay GMT One for Only Watch 2021, a unique execution of its Black Bay GMT, complete with specially finished case, bracelet and movement as well as Master Chronometer certification by METAS.

For Only Watch 2021, TUDOR has created a unique Black Bay GMT with a striking case and bracelet finish that is the result of a secret stainless-steel ageing technique. The MT5652 Manufacture Calibre powering this unique watch, capable of keeping track of time in three time zones simultaneously, also received an aesthetic treatment to match the case in style that required the bridges and mainplate to be coated in black before being aged by barrel tumbling.

The Black Bay GMT One is a Master Chronometer, one of the industry's most demanding certified standards, guaranteeing Swiss manufacturing, precision of 5 seconds (0 +5), anti-magnetism to 15’000 gauss, stated water-resistance and stated power-reserve. Achieving this certification required a substantial number of changes to the TUDOR Manufacture calibre and highlights the brand's technical expertise and know-how.
