Tudor extends its medium-sized diving watch collection with an updated version of the Black Bay 58 and a new bracelet option for the Black Bay 58 GMT model.
Both models retain the familiar 39mm case and continue to draw inspiration from Tudor's late 1950s diver watch designs. The three-hand model has received technical upgrades, altered case proportions, and Master Chronometer certification. These changes reflect Tudor's aim to standardize high technical specifications in its main collections while maintaining the signature Black Bay design.
Since its debut in 2018, the Black Bay 58 has become a favorite among watch collectors and enthusiasts worldwide. It offers a more compact size compared to the original 41mm models and is largely inspired by the 1958 reference 7924 "Big Crown." The latest version retains these proportions but introduces a slimmer case, an updated dial, and new bracelet options. Tudor is also expanding the GMT line introduced in 2024, adding new bracelet options. Notably, both the three-hand and four-hand models now align with Tudor's wider transition to METAS Master Chronometer certification.
Overview of Tudor Black Bay 58
The updated Black Bay 58 remains an attractive stainless steel diver's watch with a 39mm case diameter. The case thickness has been reduced by 0.2mm, lowering the watch profile to 11.7mm. The unidirectional bezel features a 60-minute scale with a red triangle at the 12 o'clock position. The slightly domed matte dial retains gold accents and applied markers filled with Super-LumiNova.
The "Snowflake" hands remain, although they have been slightly revised at the base - similar changes were made to the Black Bay in 2024. The second hand now features a "lollipop" detail inspired by early Tudor diving models. The dial text is reduced to two lines, matching other Master Chronometer certified models. The redesigned crown now sits closer to the case, while water resistance remains at 200 meters.
The watch is powered by the in-house MT5400-U caliber produced by Kenissi. This automatic movement displays hours, minutes, and seconds, features a silicon balance spring with variable inertia, and provides a power reserve of up to 65 hours. The movement is first certified as a COSC chronometer before the completed watch undergoes METAS testing. In addition to the riveted three-link bracelet, Tudor now offers the Black Bay 58 on a five-link stainless steel bracelet or a custom-fit rubber strap. All options feature a T-fit clasp with tool-free micro-adjustment.
Overview of Tudor Black Bay 58 GMT with New Bracelet Option
Technically, there are no changes in the Black Bay 58 GMT model. The case dimensions remain at 39mm in diameter and 12.8mm in thickness, as in the model introduced in 2024. However, unlike the three-hand Black Bay 58 version, the GMT features a bezel with a 24-hour scale in burgundy and black tones with gold numerals instead of a 60-minute diver's scale.
The matte black dial retains gold accents, applied markers, and signature "Snowflake" hands. The fourth hand handles the GMT function, while the main 12-hour hand can be adjusted independently in one-hour increments, making the watch convenient for travel. The case is thinner than the larger Black Bay GMT models with a 41mm diameter, preserving the compactness and wearability characteristic of the 58 series. Water resistance also remains at 200 meters, despite the more complex mechanism.
Inside the case is the MT5450-U caliber produced by Kenissi. This movement has a 65-hour power reserve, a silicon balance spring, and COSC and METAS Master Chronometer certification. The new addition is the expanded bracelet options: the GMT model is now offered on a five-link bracelet. The custom-fit rubber strap and riveted three-link bracelet remain available options. All versions feature a T-fit clasp.
First Impressions
Tudor continues to refine its collection, and the updated Black Bay 58 is another step in this direction. The new model offers a slimmer case, an updated dial layout, and a METAS certificate. An important improvement is the expanded choice of bracelets for both versions - the classic three-hand and the GMT. Both options retain the key 39mm size that has defined the Black Bay 58 series since 2018 and introduce subtle yet significant updates.
As for pricing, the Black Bay 58 GMT on a five-link bracelet is priced at €5,220 / US$5,650 / CHF 4,600, while the enhanced Black Bay 58 Master Chronometer on the same bracelet is priced at €4,920 / US$5,350 / CHF 4,350. The most affordable version on a rubber strap costs €4,580 / US$4,975 / CHF 4,050. For more detailed information, we recommend exploring the full Tudor Black Bay 58 lineup.
