Meet the Black Bay 58 GMT, the newest member of the Black Bay line, featuring the Black Bay 58's signature 39mm case, now in GMT form, paired with warm hues of burgundy, black and gilt on the 24-hour bezel. Available with a stainless steel "rivet-style" bracelet. 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.
