Black Bay 58 GMT

The Tudor Black Bay 58 GMT, reference M7939G1A0NRU-0001, is a welcome evolution of Tudor’s most iconic dive watch, now equipped with practical dual time functionality in a perfectly sized 39 mm case. This certified pre-owned 2024 model is offered in good condition and comes as a full set, with original box, warranty card, and all accessories.

Crafted from stainless steel, the 39 mm case maintains the slim profile and vintage proportions of the Black Bay 58 line. It is paired with a 24-hour bidirectional bezel in black and burgundy aluminum, a clear nod to heritage GMT designs. The result is a watch that blends tool-watch ruggedness with everyday versatility.

The black dial features Tudor’s signature snowflake hands, applied lume-filled hour markers, and a red-tipped GMT hand for tracking a second time zone. The domed sapphire crystal and vintage-inspired layout make it both practical and visually striking.

At its core is the Tudor Manufacture Calibre MT5450-U, a COSC-certified and METAS Master Chronometer movement that offers outstanding precision, anti-magnetism, and a solid 65-hour power reserve. It is also the first Tudor GMT movement to meet METAS standards, offering technical performance on par with the very best in the industry.

Fitted with a rivet-style steel bracelet and T-fit clasp, the watch ensures optimal comfort and adjustability throughout the day.

As a certified pre-owned Tudor, this Black Bay 58 GMT has been professionally inspected and authenticated. It is in good condition, showing light signs of wear consistent with careful use, and includes its full set of original accessories.

A perfect travel companion and a future classic, the Black Bay 58 GMT offers vintage styling, modern specs, and true GMT functionality in one highly wearable package.
