The latest Black Bay that matches TUDOR’s 2026 launch announcement is the updated 39 mm Black Bay 58, reference 7939A1A0NU. It keeps the model’s compact dimensions and 200 m water resistance while bringing a slimmer case, a revised bezel, crown, dial and hands, and a new five-link bracelet option. The detailed specifications and U.S. launch prices below were reported by Hodinkee on April 14, 2026; they are launch figures, not live quotes.
What is the latest Tudor Black Bay?
TUDOR’s 2026 new-watches page describes a Black Bay 58 with “a host of new technical and aesthetic enhancements.” The launch coverage identifies the 39 mm update as reference 7939A1A0NU. That identification matters: “latest Black Bay” can also refer to other watches in the family, including the 41 mm monochrome Black Bay introduced in 2024.

The updated Black Bay 58 is a further evolution of the 58-sized model, not that separate 41 mm watch. TUDOR’s launch overview also mentions a Black Bay Ceramic, a blue Black Bay 54, and a Black Bay 58 GMT, so the 58 update is one part of a broader 2026 Black Bay lineup.
What changed on the updated Black Bay 58?
Hodinkee’s April 14, 2026 launch report describes a slightly slimmer case and changes to the bezel, crown, dial and hands. The 39 mm case size remains. The most visible configuration addition is a five-link steel bracelet alongside the three-link bracelet and rubber strap.

- Tudor Black Bay 58 GMT "Coke" Automatic 39mm Black Dial Men's Watch M7939G1A0NRU-0001
The report lists the watch’s principal specifications as follows:
| Specification | Updated Black Bay 58 |
|---|---|
| Reference | 7939A1A0NU, as identified in Hodinkee’s April 14, 2026 launch report |
| Case | Stainless steel; 39 mm diameter and 11.7 mm thickness, as reported by Hodinkee on April 14, 2026 |
| Bezel | Unidirectional, with a 60-minute scale |
| Dial | Matte, domed black |
| Water resistance | 200 m, as reported by Hodinkee on April 14, 2026 |
| Movement | Manufacture Calibre MT5400-U; self-winding, silicon hairspring, 4 Hz frequency and 65-hour power reserve, as reported by Hodinkee on April 14, 2026 |
| Certification | COSC and METAS Master Chronometer, as reported by Hodinkee on April 14, 2026 |
Movement and certification: what the figures mean
The reported MT5400-U has a 65-hour power reserve and beats at 4 Hz. Its silicon hairspring is part of the movement specification, while COSC and METAS Master Chronometer are separate certification designations. These are figures for the updated 39 mm Black Bay 58 as reported at launch; they should not be confused with specifications for other Black Bay references.
Rank #2
- Tudor Black Bay Fifty Eight Automatic Chronometer Blue Dial Men's Watch M79030b-0001
For example, TUDOR’s official material for the burgundy-bezel Black Bay names calibre MT5602-U, a 70-hour reserve and a 0/+5 seconds-per-day tolerance. Those are not the MT5400-U specifications reported for the 2026 Black Bay 58.
Bracelet and strap options, with U.S. launch prices
Hodinkee reported three configurations, each with TUDOR’s T-fit clasp. The dollar figures are U.S. launch prices published April 14, 2026, not a guarantee of current pricing or availability.

- Main Material: Stainless Steel
- Case Size: 39mm Steel Case with Polished and Satin Finish
- Series: Black Bay 58
- Dial Hue: Burgundy
- Movement Type: Manufacture Calibre MT5400-U; Self-winding Mechanical Movement with Bidirectional Rotor System
| Configuration | U.S. launch price reported April 14, 2026 |

| Three-link rivet-style steel bracelet | $5,225 |
| Rubber strap | $4,975 |
The five-link bracelet is the new choice highlighted in the launch coverage. The three-link option offers a more traditional tool-watch look, while the rubber strap gives the lineup a non-metal alternative. All three are reported with T-fit clasps; check a TUDOR retailer for current local pricing and stock.
How this update fits into the Black Bay timeline
The Black Bay family began in 2012 with a burgundy-bezel model. TUDOR says the original line received a manufacture calibre in 2016. The family now includes watches that share the Black Bay name but differ in size, movement and design, which makes generation labels easy to mix up.
Rank #4
- Tudor Black Bay 58 GMT "Coke" Automatic Black Dial Men's Watch M7939G1A0NRU-0002
- 2026 Black Bay 58 update: the 39 mm model covered here, reference 7939A1A0NU, with the reported MT5400-U movement.
- 2024 monochrome Black Bay: a distinct 41 mm model. TUDOR’s press material lists the MT5602-U, a 70-hour reserve, METAS Master Chronometer certification, and three-link, five-link or rubber-strap options.
- Burgundy-bezel Black Bay: another separate model; TUDOR’s official family material describes its third evolution and lists the MT5602-U.
Those distinctions are important when comparing specifications or shopping by reference. The 2024 41 mm watch’s movement and 70-hour reserve do not describe the 2026 39 mm Black Bay 58.
