In 1969, TUDOR introduced a divers’ watch with a blue dial and bezel. The other sporty watches in the collection were soon attired in blue, immediately creating a lasting aesthetic hallmark known as “TUDOR Blue”. Adopted by the French navy for its TUDOR divers’ watches during the 1970s, this livery became part of the collective imagination. The Black Bay Fifty-Eight “Navy Blue” follows in this tradition with its navy blue dial and bezel insert
