The Black Bay is the line that rebuilt modern Tudor. From the original Heritage Black Bay 79220 in 2012 to the current 17-reference family covering everything from 37mm slim divers to 41mm chronographs and GMT travelers, the Black Bay has become the single most important collection in the Tudor catalog. It is also the most confusing. Naming conventions shifted twice. Reference numbers moved from 79220-style to 79030N to the current 7941A1A0NU/M79030N hybrid. Modern Black Bays carry either Tudor's in-house Manufacture Calibre family (MT5400, MT5602, MT5612, MT5813) or, in the case of older pieces, ETA-based movements.
This guide decodes the entire current Black Bay family. The BB58, the BB41, the BB54, the GMT, the BB58 GMT, the Pro, the Chrono, the Bronze, the S&G two-tone, the Ceramic, and the Heritage references that defined the line before the modern restructuring. Retail and pre-owned pricing as of May 2026. For the BB58-specific deep dive, see our dedicated Tudor Black Bay 58 Buying Guide.

The Short Answer
The current Black Bay family spans $3,400 to $11,200 retail depending on size, complication, and material. The Black Bay 41 (7941A1A0NU monochrome configuration) is the volume entry at roughly $3,800 retail. The BB58 sits at $3,475 to $4,400 depending on reference. The BB54 is $4,575 retail. The GMT runs $4,775. The Pro at $4,950. The Chrono at $5,775. The Bronze at $4,900. The S&G two-tone at $5,700. The Black Bay Ceramic Pro at $6,225.
Pre-owned secondary market trades at or below retail across nearly every reference. WatchCharts data through April 2026 shows the BB54 at $3,330 secondary (27% below retail), the BB Pro at $2,967 secondary (40% below retail), and the BB Chrono panda at $4,200 secondary (versus $5,775 retail). The BB58 is the exception — certain BB58 configurations trade at or slightly above retail.
For most buyers, the BB58 is still the best single purchase in the Tudor catalog. The BB54 is the small-wrist alternative. The BB GMT is the most credible Rolex GMT-Master II waitlist exit. The BB Pro is the deepest pre-owned discount and the most underrated piece in the family.
The Modern Black Bay Family: Quick Reference
| Model | Size | Retail (May 2026) | Pre-Owned Range |

The Black Bay 41 (BB41)
The Black Bay 41 is the volume entry into the modern Tudor diver. Built on the original 41mm Heritage Black Bay platform but updated to current proportions, materials, and movements. The 2024 monochrome reference (7941A1A0NU) on Jubilee-style five-link bracelet is the current bestseller across the entire Tudor catalog.
| Spec | Detail |
|---|---|
| Case | 41mm satin-brushed stainless steel, 12.7mm thick, 200m water resistance |
| Bezel | Unidirectional, aluminum insert (black, burgundy, blue depending on config) |
| Movement | Calibre MT5602 (Tudor manufacture), 70-hour power reserve, COSC certified |
| Bracelet | Five-link Jubilee-style, steel rivet-style Oyster, or fabric strap |
| Retail (May 2026) | $3,800 (monochrome) - $4,200 (burgundy/Black Bay One) |
| Secondary market | $3,600 - $4,000 |
WatchCharts puts the 7941A1A0NU as the most popular Tudor reference by transaction volume through Q1 2026, ahead of the BB58. The 41mm sizing fits the broader luxury-diver audience that wants Submariner proportions at a third of the Submariner price. The Jubilee bracelet release in 2024 added a configuration that has performed particularly well on the secondary market.
The 41mm sizing is the differentiator. Buyers who find the 39mm BB58 slightly under-proportioned for their wrist or against current Submariner conventions land on the BB41 instead. The MT5602 is the heart of the family.
The Black Bay 58 (BB58)
The BB58 is the modern Tudor benchmark. Launched in 2018, updated for METAS certification in 2024, and refreshed again at Watches and Wonders 2026 with the burgundy 7939A1A0RU and the gilt-accent 7939A1A0NU. Smaller case (39mm), slimmer profile, vintage-proportion appeal. The default answer to "what Tudor should I buy first."
We covered the BB58 in detail in our Tudor Black Bay 58 Buying Guide. For the broader family context here: the BB58 sits at the geometric center of the Black Bay line. Smaller than the BB41, larger than the BB54, more affordable than the BB GMT, simpler than the BB Pro. METAS certification (added in 2024) places it on a higher accuracy spec than most non-MT5602 references in the catalog. Most BB58 configurations trade at or slightly above retail on the secondary market, a rare position in the broader Tudor lineup.
The Black Bay 54 (BB54)
The BB54 is the smallest and slimmest Black Bay at 37mm and 11.24mm thick. The reference is built around the proportions of the 1954 Tudor Oyster Prince Submariner 7922, the original Tudor diver.
The Black Bay 54 launched in 2023 as the small-wrist Black Bay. Built around the proportions of the 1954 Tudor Submariner 7922 (the original Tudor diver), the BB54 is the smallest and slimmest reference in the entire current Black Bay family.
| Spec | Detail |
|---|---|
| Case | 37mm satin-brushed stainless steel, 11.24mm thick (slimmest BB) |
| Bezel | Unidirectional, black aluminum insert |
| Movement | Calibre MT5400 (Tudor manufacture), 70-hour power reserve, COSC |
| Bracelet | Three-link rivet-style steel Oyster bracelet |
| Retail (May 2026) | $4,575 |
| Secondary market | $3,300 - $3,500 (27% below retail) |
The BB54 trades at a 27% discount to retail per WatchCharts, the deepest current-production Black Bay discount short of the BB Pro. Demand has not matched the BB58 or BB41 despite strong critical reception. The 37mm sizing is the constraint: buyers shopping at this price point typically want the 39mm or 41mm options.
That secondary discount is the buyer's opportunity. The BB54 sells in a median of 11 days when listed, faster than 97% of watches on the market. The reference also recently launched in a Lagoon Blue colorway (2025) that has been the strongest selling BB54 configuration since.
For smaller-wrist buyers or buyers who want the most vintage-proportioned modern Black Bay, the BB54 is the answer. The slim profile (11.24mm) is the practical advantage; most divers in this price range sit closer to 13mm.
The Black Bay GMT
The 41mm Black Bay GMT 79830RB with the iconic blue-and-red Pepsi aluminum bezel and yellow snowflake-tipped GMT hand. The reference launched in 2018 as Tudor's first GMT and remains the most credible Rolex Pepsi alternative at one third the price.
The Black Bay GMT 79830RB launched in 2018 and remains the credible alternative to the Rolex GMT-Master II Pepsi (now discontinued, as we covered in our Pepsi GMT discontinuation market impact and GMT-Master II buying guide).
| Spec | Detail |
|---|---|
| Case | 41mm stainless steel, 14.6mm thick |
| Bezel | Bidirectional aluminum, blue/red ("Pepsi") or black/grey ("Coke") or black/burgundy |
| Movement | Calibre MT5652 (Tudor manufacture), true GMT (independent hour jump), 70-hour PR, COSC |
| Bracelet | Three-link rivet-style steel Oyster, or fabric strap |
| Retail (May 2026) | $4,775 |
| Secondary market | $3,500 - $3,900 |
The BB GMT is what the Rolex Pepsi cost before authorized dealer pricing and waitlists became impossible. The MT5652 is a true (flyer) GMT, meaning the local hour hand jumps independently in one-hour increments — the function that defines a GMT-Master II rather than a "caller" GMT. The aluminum bezel ages with character that ceramic does not reproduce. The 41mm case is slightly thicker than the BB41 due to the GMT module.
For buyers exiting the Rolex GMT waitlist after the Pepsi discontinuation, the BB GMT is the most direct conversion. We covered this in detail in our Rolex Pepsi waitlist dealer advice piece.
The Black Bay 58 GMT
Launched at Watches and Wonders 2024 in the BB58 39mm case with a true METAS-certified flyer GMT movement. Refreshed at W&W 2026 with the new five-link bracelet option (7939G1A0NU/RU/NRU configurations). The 39mm sizing is the differentiator from the BB GMT.
The BB58 GMT is the smartest mid-size travel watch in the broader luxury sport catalog. METAS certification places it above the BB GMT on accuracy spec. The 39mm case fits wrists that find the 41mm BB GMT too thick (14mm+) for everyday wear. We covered the BB58 GMT case in full in Tudor Black Bay 58 GMT 2026: The Mid-Size Travel Watch That Beats the Rolex GMT Waitlist.
Retail $4,725. Secondary market $3,800 to $4,500 depending on year and bracelet configuration. The Coke colorway (black/burgundy) was added in 2024. The Pepsi colorway is the volume seller. The five-link Jubilee bracelet added in 2026 is the most popular current configuration.
The Black Bay Pro
The Black Bay Pro 79470 is the fixed-bezel GMT with engraved 24-hour scale in polished steel. Retail $4,950, secondary $2,900-$3,200. The deepest pre-owned discount in the current Black Bay family.
The Black Bay Pro 79470 launched at Watches and Wonders 2022 with explicit Rolex Explorer II 16570 styling cues. Fixed bezel with engraved 24-hour scale, yellow square-tipped GMT hand, matte black dial. The reference is the most underrated current Black Bay.
| Spec | Detail |
|---|---|
| Case | 39mm stainless steel, 14.6mm thick |
| Bezel | Fixed steel with engraved 24-hour scale, no rotation |
| Movement | Calibre MT5652 (Tudor manufacture), true flyer GMT, 70-hour PR, COSC |
| Bracelet | Three-link rivet-style steel Oyster |
| Retail (May 2026) | $4,950 |
| Secondary market | $2,900 - $3,200 (40% below retail) |
WatchCharts data shows the BB Pro at $2,967 secondary against $4,950 retail. That is a 40% discount to retail on a current-production reference with a true flyer GMT movement. The volatility metric is higher than most Tudor references (13.9%, higher than 67% of qualifying watches), driven by the wide spread of available pre-owned inventory.
The market criticism of the BB Pro at launch was the case thickness (14.6mm for a fixed-bezel GMT) and the visual proximity to the Rolex Explorer II. Three years in, that criticism has stabilized into a secondary market discount that makes the BB Pro one of the best price-per-spec values in the modern Swiss catalog. For buyers who want a true flyer GMT with no rotating bezel (the Explorer II positioning), the BB Pro at $2,900-$3,200 is the best in class.
The Black Bay Chrono
The Black Bay Chrono 79360N panda is the bicompax chronograph configuration. The MT5813 movement is built on a Breitling B01 base, modified for Tudor and COSC certified.
The Black Bay Chrono 79360 launched in 2017 as Tudor's first in-house chronograph movement. The MT5813 is built on a Breitling B01 base, modified by Tudor for column-wheel construction, vertical clutch, and COSC certification. The 2024 update refined dial layout and added the panda (white-dial-black-subdials) and reverse panda (black-dial-white-subdials) configurations.
| Spec | Detail |
|---|---|
| Case | 41mm stainless steel, 14.9mm thick |
| Bezel | Fixed steel with engraved tachymeter scale |
| Movement | Calibre MT5813 (Tudor manufacture, Breitling B01 base), column-wheel, 70-hour PR, COSC |
| Sub-dials | Bicompax (30-minute counter at 3 o'clock, running seconds at 9 o'clock) |
| Retail (May 2026) | $5,775 |
| Secondary market | $4,100 - $4,400 |
The BB Chrono is the most underappreciated chronograph in the sub-$6,000 Swiss market. The MT5813 is genuinely competitive against any non-Daytona Swiss chronograph at the price. The panda dial reads as a Daytona homage but with bicompax layout (versus Daytona's tri-compax). For buyers building a Tudor pillar alongside their Rolex Daytona ambition (see our Daytona Buying Guide), the BB Chrono is the practical chronograph in a collection.
The 41mm case at 14.9mm thick is the constraint. Smaller wrists will find it overwhelming. The bicompax layout reads cleaner than the tricompax Daytona for daily-wear utility.
The Black Bay Bronze
The Black Bay Bronze launched in 2016 as the patina-developing alternative to the steel BB. The 43mm case is bronze alloy (CuSn8, aluminum bronze) that develops a unique patina with each owner's wear. Brown bezel, brown or matching dial, brown leather or fabric strap.
Retail sits at $4,900. Secondary market trades at $2,800 to $3,400 depending on patina development and condition. The bronze patina is the entire selling proposition; collectors who want a polished-bronze new piece typically choose steel instead. Buyers who want a watch that ages visibly with wear choose bronze.
The 43mm case is the largest in the modern Black Bay family. Bronze develops oxidation green-blue patina at the lugs and around the crown over multiple years of wear. Brushing or polishing the case removes the patina; doing nothing develops it.
The Black Bay 36 and 31
The Black Bay 36 (and the smaller 31mm) are the dressier no-bezel Black Bay variants. Polished bezel surround instead of dive bezel. Available in steel, two-tone S&G, and various dial configurations. Retail $3,400 (BB31) to $3,550 (BB36). Secondary market sits at $2,900 to $3,400.
The BB36 is the practical unisex Black Bay for buyers who want the snowflake-hand aesthetic without the dive-bezel commitment. The BB31 fits smaller wrists. Both run the MT5400 movement (the smaller of the manufacture caliber family).
The Black Bay S&G (Two-Tone Steel and Gold)
The Black Bay S&G 79733N launched in 2016 as the two-tone Black Bay. Steel case with a gold bezel, gold crown, and gold center bracelet links. Champagne sunburst dial. Retail $5,700. Secondary market $4,800 to $5,400.
The S&G follows the broader two-tone Rolesor pattern: two-tone trades close to retail on the secondary market, sometimes at small discount. The S&G has been one of the steadier-pricing Black Bays across the post-2022 market correction. For buyers who want yellow gold accents at a steel-Black-Bay price point, the S&G is the answer.
The Black Bay Ceramic and Master Chronometer Variants
The Black Bay Ceramic Pro 79360DK is the all-ceramic version of the BB Chrono with the MT5813 movement. Released in 2021 as Tudor's first Master Chronometer-certified piece (METAS), the reference is built on a ceramic monobloc case construction. Retail $6,225.
The newer Black Bay One 7941A1A0RU (2026 W&W release) is the centennial-year burgundy configuration on the new five-link bracelet. Retail $4,200. Secondary market $4,000 to $4,400.
The Movement Family
Tudor's Manufacture Calibre family powers the modern Black Bay:
| Calibre | Power Reserve | Function | Used In |
|---|---|---|---|
| MT5400 | 70 hours | Three-hand | BB54, BB36, BB31 |
| MT5402 | 70 hours | Three-hand (older spec) | Older 41mm Black Bay |
| MT5602 | 70 hours | Three-hand (METAS spec, current) | BB41 monochrome, current BB58 |
| MT5612 | 70 hours | Date | Older BB41, BB36 date variants |
| MT5652 | 70 hours | Flyer GMT | BB GMT, BB Pro |
| MT5652-U | 70 hours | Flyer GMT (METAS spec) | BB58 GMT |
| MT5813 | 70 hours | Chronograph (Breitling B01 base) | BB Chrono, BB Ceramic Pro |
All Tudor Manufacture calibers are COSC certified at minimum (-4/+6 sec/day). METAS-certified variants (MT5602, MT5652-U) hold to a tighter -2/+4 sec/day standard plus magnetic resistance testing to 15,000 gauss. The MT5813 in the Black Bay Chrono Ceramic Pro is also METAS certified. Service intervals run roughly 7 to 10 years on properly worn examples, consistent with Rolex caliber 32xx and 33xx family service intervals.
What Should You Actually Buy?
If this is your first Tudor: The BB58 (any current configuration). The 39mm sizing fits the broadest range of wrists, the METAS-certified MT5602 is the best three-hand caliber in the Tudor catalog, and the secondary market holds value better than any other Black Bay. See our dedicated BB58 buying guide for the detailed reference walk.
If you want value per spec: The BB Pro. 40% below retail on the secondary market, true flyer GMT movement, the most credible Explorer II homage in the sub-$5,000 catalog.
If you have a small wrist: The BB54. 37mm, 11.24mm thick, the slimmest Black Bay. 27% below retail on the secondary market. The Lagoon Blue dial added in 2025 is the most distinctive current configuration.
If you want a GMT but can't get a Rolex Pepsi: The BB GMT (41mm) or the BB58 GMT (39mm). Both run true flyer GMT movements. The BB58 GMT is the smarter long-term piece due to METAS certification and slimmer case profile. See our BB58 GMT analysis.
If you want a chronograph: The BB Chrono panda 79360N. The MT5813 is genuinely competitive against any non-Daytona Swiss chronograph at the price. Pre-owned at $4,100-$4,400 against $5,775 retail.
If you want a watch that ages visibly: The BB Bronze. The patina is the proposition.
If you want a two-tone: The S&G. Steel case, gold accents, champagne dial. Trades close to retail.
If you want the highest-spec Tudor: The Black Bay Ceramic Pro 79360DK. All-ceramic case, METAS-certified MT5813 chronograph. Retail $6,225, secondary $4,800-$5,800.
The Working Dealer's Bottom Line
The Black Bay family is the most thorough single-collection coverage in the modern Swiss luxury sport catalog. Sizes from 31mm to 43mm. Three-hand, date, GMT, chronograph. Steel, bronze, ceramic, two-tone. Aluminum bezels, fixed steel bezels, ceramic bezels. Manufacture calibers with 70-hour power reserves. COSC certification minimum, METAS certification on flagship references.
For collectors building a Tudor pillar — particularly alongside a Rolex sport collection (see our Rolex versus Tudor decision tree) — the Black Bay is the anchor. The Pelagos 39 (see our Pelagos 39 buying guide) is the technical-diver alternative. The Monarch (covered in our Tudor Monarch deep dive) is the integrated-bracelet alternative. The broader Tudor centennial program (see our Tudor 100th anniversary dealer take) gave the brand a full year of pricing power that the secondary market has not yet fully absorbed.
Pre-owned Black Bay buying remains the strongest value play in the sub-$5,000 Swiss catalog. The BB54, BB Pro, and BB Chrono all trade meaningfully below retail. The BB58 and BB GMT hold value closest. The 2026 W&W refresh added new bracelet configurations and centennial-year burgundy variants that have stabilized rather than disrupted the broader pricing structure.
