The Black Bay 54 is the most true-to-form example of TUDOR’s first dive watch, the reference 7922. The 37mm case retains the classic proportions of yesteryear yet boasts the technical prowess of TUDOR’s time-only Manufacture Calibre MT5400 and a 200m depth rating.
TUDOR presents a new addition to the Black Bay 54 line in "TUDOR blue", with a sapphire blue dial and bezel, paired with a perfectly proportioned 37mm case and a Manufacture Calibre. A special version dubbed “Lagoon Blue” is inspired by the colour of tropical oceans and features a sand-textured “Lagoon Blue” dial, a five-link bracelet and a mirror-polished bezel.
