The Black Bay P01 – which stands for prototype 1 – is a watch based on a legendary prototype developed in the late 1960s and proposed to the US Navy. It reflects the exploratory nature of the project, a cross between a divers' watch and a sailing watch. The Black Bay P01 lifts the veil on a little-known aspect of TUDOR’s history, with its unique aesthetic brought to life and mass-produced 50 years later.
