The Tudor Black Bay 54 M79000N-0001 is a modern reinterpretation of Tudor's 1954 Oyster Prince Submariner, combining vintage aesthetics with contemporary technology. Its 37mm stainless steel case features a polished and satin finish, housing a black, domed dial protected by a domed sapphire crystal. The watch is powered by the in-house Calibre MT5400, a COSC-certified self-winding mechanical movement with a 70-hour power reserve. A 60-minute unidirectional bezel in stainless steel with an aluminum insert complements the design. The timepiece is water-resistant up to 200 meters and comes with a three-link stainless steel bracelet featuring a TUDOR “T-fit” clasp.
