Tudor Black Bay 58 (2026 generation, ref. M7939A1A0NU-0001)

The new-generation Tudor Black Bay 58 (ref. M7939A1A0NU-0001) is the centennial redesign unveiled at Watches & Wonders 2026, built on a new movement platform — Calibre MT5400-U — and, for the first time in this line, a black dial on a Jubilee bracelet. No verified market price exists as of today. Several technical specs (case diameter, power reserve, water resistance) are not confirmed in the announcement reviewed and are marked unverified rather than inferred.

History

Tudor unveiled this new Black Bay 58 generation at Watches & Wonders 2026, timed to the brand's centennial (Tudor was founded in 1926). It is the deepest redesign the line has received since its original 2018 launch (the outgoing generation, documented in Cazador's fiche for ref. 79030N), built around a new movement platform: Calibre MT5400-U.

Two facts are confirmed by the brand announcement reviewed: the new MT5400-U caliber, and the pairing of a black dial with a Jubilee bracelet — a configuration the Black Bay 58 had not previously offered, since the Jubilee was not among the outgoing reference's factory strap options.

Beyond those two facts, the announcement reviewed does not provide a complete technical specification. Exact case diameter, case material, power reserve, water resistance, chronometric certification, and bezel type are not confirmed in the source available at the time of writing. As an editorial discipline, these fields are marked unverified in the specs table rather than inferred from the outgoing generation (79030N), which runs a different movement platform (Calibre MT5402).

Given how recently this reference was unveiled, Cazador has no market price observations yet, nor confirmation of retail availability. This fiche will be updated once Tudor publishes the full technical specification and verified price data exists.

Frequently asked questions

What changes on the new 2026 Tudor Black Bay 58 versus the 79030N?

The confirmed changes are the new MT5400-U caliber and a black dial paired with a Jubilee bracelet, unprecedented for this line. The rest of the specification is not yet confirmed in the announcement reviewed.

What is Tudor's Calibre MT5400-U?

It's the new movement platform Tudor introduced alongside this reference at Watches & Wonders 2026. Detailed technical data (power reserve, certification) is not confirmed in the announcement reviewed.

How much does the new Tudor Black Bay 58 (ref. M7939A1A0NU-0001) cost?

What is the case diameter of the new Black Bay 58?

It is not confirmed in the announcement reviewed. We do not infer a measurement from the outgoing generation (39mm) in order to avoid publishing an unverified figure.
