The Tudor Heritage Black Bay One was made in 2015 for the Only Watch auction. It's a unique piece based on the regular Black Bay model. This version has some cool changes that give it the look of Tudor's first Submariner watch from 1955. Instead of the usual Snowflake hands, it has pencil-shaped ones in a 'gilt' color to match the faux-patina luminous markers. The black bezel also has a red triangle and depth rating in meters. And the bracelet has a straight-end design.
