The ref. 7923/001 Tudor Heritage Black Bay One was created in 2015 as a piece unique for the Only Watch auction. Based on the regular Black Bay model, this watch features several distinct modifications that make it resemble the brands first Submariner watch - reference 7923.
The so-called Snowflake hands found on the regular production model have been replaced with pencil-shaped ones in 'gilt' coloring, matching the surrounds of the faux-patina luminous plots. It furthermore features a red triangle on its black diving-scale bezel inlay, red depth rating in so-called Meters First configuration and a straight-end bracelet.
