Details & Specifications
Description:
The Tudor Black Bay 54 "Lagoon Blue" reference M79000-0001 draws inspiration from the Oyster Prince Submariner reference 7922, one of Tudor's earliest diving watches, reimagined in a compact and historically faithful 37mm case. The stainless steel case is fitted with a unidirectional bezel with a mirror-polished steel insert devoid of minute graduations, surrounding a lagoon blue, domed and textured dial. The dial's subtle sand-textured finish pays homage to the vintage original, while the case features a screw-down crown with the Tudor rose in relief and a domed sapphire crystal.
Powered by the in-house Manufacture Calibre MT5400, this COSC-certified chronometer movement uses a bidirectional rotor system and delivers approximately 70 hours of power reserve. The watch is fitted on a five-link stainless steel bracelet with Tudor's "T-fit" clasp for on-the-fly micro-adjustment.
