TUDOR Black Bay 58 – M7939A1A0NU-0001
Updated Case Design and Aesthetics
The new Black Bay 58 redefines comfort and style with a redesigned 39 mm case, featuring a slimmer profile of just 11.7 mm thickness. This aesthetic evolution reduces the dial text to two lines, in line with its new high-end certification, and updates key elements such as the crown and bezel for a more technical and refined appearance.
Master Chronometer Movement (METAS)
Beating inside is the Manufacture Calibre MT5400-U, a self-winding mechanical movement that has passed the demanding METAS tests. This certification guarantees extreme precision, resistance to magnetic fields of up to 15,000 gauss, and a 65-hour power reserve, consolidating it as a benchmark of modern Swiss watchmaking.
Iconic Design and Ergonomics
True to its diving roots, the watch maintains the iconic “lollipop” seconds hand and the domed matte black dial reminiscent of the brand’s early technical models. The unidirectional rotatable bezel offers superior grip, while the redesigned screw-down crown integrates perfectly into the case middle for improved ergonomics.
Unprecedented Comfort
This model comes equipped with a 5-link stainless steel bracelet with polished and satin finishes. The major highlight is the incorporation of the TUDOR “T‑fit” quick-adjustment system, which allows the bracelet to be adapted instantly and easily, ensuring a perfect fit in any situation.
