About this reference
The Tudor Black Bay Ceramic One reference M7921P-0001 is a unique piece produced specifically for the 2019 Only Watch charity auction. Unlike the standard production Black Bay Ceramic released later in 2021, this specific reference features a 41mm matte black ceramic case with a matching ceramic bezel insert and a unique matte black dial with blacked-out markers and hands. It is powered by the MT5602-1U manufacture caliber, which was the first Tudor movement to receive METAS Master Chronometer certification. This reference is a one-of-one production, making it a significant historical marker for the brand’s technical evolution. At the 2019 Only Watch auction, it achieved a final sale price of 350,000 CHF, which was approximately 70 times its low estimate. Because it is a unique piece held in a private collection, it does not have a standard secondary market price range.
