TUDOR Black Bay 58 GMT – M7939G1A0NRU-0002



The Black Bay 58 is named after the first-ever TUDOR dive watch waterproof to 200m, the reference 7924, released in 1958. Known as the “Big Crown” among collectors, the design of the Black Bay 58 makes aesthetic references to this historic model. This year sees two new additions to the Black Bay 58 family: the Black Bay 58 18k with a solid gold bracelet and the Black Bay 58 GMT reminiscent of the mid-century jet-setting era.



The TUDOR Black Bay 58 GMT has undergone a series of rigorous tests in order to achieve the status of Master Chronometer, awarded by METAS.
