The Tudor Black Bay P01 was added to the collection in 2019. Its unique design is inspired by a mythical prototype proposed to the US navy in the late 1960's. The stainless steel case measures 42mm across. It features a 60-notch, 12-hour graduated steel bidirectional rotating bezel with stop system for the bidirectional rotating bezel via a mobile end-link at 12 o'clock. It is strapped to the wrist through a hybrid leather and rubber strap with folding clasp and safety catch, entirely satin-finished.
