The Black Bay 58 18K is the first TUDOR divers’ watch to be made in 18 ct solid yellow gold, offered with an open case back. And now it comes with a matching all satin-finished 18 ct yellow gold bracelet to boot.

Entirely satin-finished for a matt effect, the 18 ct yellow gold case is another first for a TUDOR divers’ watch. An open case back reveals the new Manufacture Calibre MT5400. The matt 18 ct yellow gold of the Black Bay 58 18K is emphasised by the combination of dial and bezel, which are a rich “golden green” in tone with matt gold details. A colour palette fittingly matched by the fabric strap offered with this model, complete with 18 ct yellow gold buckles.

Another first for a TUDOR diving watch, the Black Bay 58 18K now comes with a solid gold 3-link bracelet featuring the TUDOR “T-fit” clasp, an ingenuous system for rapid length adjustment. Easy to use, requiring no tools and offering five positions, this practical touch allows wearers to carry out a fine, instant adjustment of the total length of the bracelet along an adjustment window of 8mm. The clasp features ceramic ball bearings that ensure a smooth and secure closure in addition to adding a pleasing tactile element to the action of the clasp.
