The Tudor Black Bay | family history

Tudor launched the Black Bay in 2012 as an explicit nod to its own vintage dive watch heritage, specifically the Submariners it made under Rolex's umbrella from the 1950s through the 1980s. The snowflake hands, the domed dial, the rose-tone gilt chapter ring on early references: all of it points backward. The Black Bay is not an original design pretending to vintage heritage; it is an honest reinterpretation of it. What makes the Black Bay worth buying in the current market is the combination of MT5000-series in-house movements, METAS certification, and a secondary market that trades at or below retail. You can find a BB58 on Chrono24 at or under its retail price. For a 39mm diver on a METAS-certified movement with a column-wheel chronograph sibling and a GMT variant, that is genuinely unusual value.

2012–2015 · The original Black Bay: ETA-based, vintage template set

Tudor launched the Heritage Black Bay in 2012 on ETA 2824-2 movements, 41mm case, gilt-toned chapter ring, snowflake hands. Red, black, and blue bezels followed through 2013-2015. The design language was established immediately: domed crystal, flat bezel, Tudor shield on the dial. These early ETA-based references are available cheaply on the secondary market and are the entry point for budget buyers; they run well but lack the in-house movement credentials of the later generation.

No references from this era in the catalog yet.

2015–2018 · In-house MT5402/5612: the Black Bay becomes serious

Tudor introduced the MT5402 (then MT5612) in 2015: in-house automatic movements, 70-hour power reserve, COSC certification, free-sprung hairspring. The Black Bay went from 'accessible vintage-styled diver' to 'proper tool watch with a credible movement.' The GMT variant (MT5652) and the Pelagos variants shared this generation's movement architecture. For collectors evaluating Tudor seriously rather than as a 'budget Rolex,' the MT5000 generation is where the argument starts.

  • At 39mm with an in-house movement and METAS certification, this is widely cited as the strongest value proposition in the sub-$4,000 dive watch market.

2018–present · BB58: the size correction

The Black Bay 58 (ref. 79030N, 2018) corrected the case size from 41mm to 39mm and became the most-discussed Tudor in years. The 39mm case is historically accurate to the original 1950s Submariners Tudor made; it is also simply a better fit for most wrists. MT5402 inside, METAS certification from 2020. The BB58 in navy blue is the canonical reference in this family: 39mm, blued handset, correct proportions, honest price. The 925 sterling-silver variant and various limited colors are the collector editions; the standard navy is the one to start with.

2016–present · BB36, Bronze, and the size range

Tudor runs the Black Bay in 36mm (BB36, ref. M79500-0001, ETA-based, the entry-level size) and 43mm bronze (ref. 79250BM, MT5601, the patina-seeker variant). The BB36 uses an ETA T600 rather than the MT5402, which matters for buyers who care about in-house movements. The bronze case develops a natural patina and is the most polarizing case material Tudor offers; buyers either love it or don't.

2017–present · BB Chrono: the MT5813 and the B01 partnership

The Black Bay Chrono (ref. M79360N, 2017) is built on the MT5813, a chronograph movement co-developed with Breitling on the B01 base. Column-wheel, vertical clutch, 70-hour reserve. 41mm case. The BB Chrono is the best-value column-wheel chronograph in the market at anywhere near its price point; the movement is the same technical architecture as the Breitling B01 at half the price. The panda or slate dial is the choice on the standard models.

  • The 36mm Black Bay introduced in 2016, Tudor’s smallest dive-watch reference, sized closer to a mid-century field watch than to the 39mm BB58 or the 41mm Black Bay.

The line is the watch the trade points to when it explains the manufacture-tier output Tudor reached after the BB GMT.

Which ref to buy

The Black Bay family is the best value argument in mechanical watchmaking today -- but several refs in the lineup are clearly correct while others are specialty items.

  1. 1

    The correct Black Bay: 39mm, haircell chapter ring, MT5402, 70-hour power reserve.

    The case for it:
    Better proportions than the 41mm, in-house movement, COSC-adjacent performance, and a price that embarrasses most competitors at twice the cost.
    Consider instead if:
    If 39mm is genuinely too small for your wrist, the BB41 delivers the same quality in a larger case without compromise.
    Open
  2. 2

    GMT complication at Black Bay prices with a bidirectional GMT hand and COSC-rated movement.

    The case for it:
    The most capable GMT under $4,000 in current production. Travel utility and correct execution at a price that makes the competition look expensive.
    Consider instead if:
    If you do not travel across time zones regularly, the complication adds cost and dial complexity without adding daily satisfaction.
    Open
  3. 3

    41mm Black Bay for wrists that find 39mm small -- same movement, same quality, bigger case.

    The case for it:
    Identical mechanical package to the BB58 with more wrist presence. The correct choice for larger wrists without paying a premium for it.
    Consider instead if:
    The BB58 proportions are considered by most collectors to be the design peak. The 41mm is fine but the 39mm is better.
    Open
  4. 4

    In-house column-wheel chronograph with vertical clutch -- exceptional value for a manufacture chronograph.

    The case for it:
    The 79360 is the most capable chronograph you can buy for under $5,000. Column wheel, vertical clutch, in-house caliber. The competition charges three times as much for this spec.
    Consider instead if:
    Chronograph cases are larger and more complex. If you do not use the chronograph function, you are paying for capability you will not use.
    Open
  5. 5

    36mm Black Bay for collectors who want a historically appropriate case size -- same movement technology.

    The case for it:
    At 36mm, this is the most wearable Black Bay for smaller wrists and the most appropriate for formal occasions.
    Consider instead if:
    The BB58 at 39mm is considered by most collectors to be the correct case size for the design. The 36mm is niche.
    Open
  6. 6

    Bronze case Black Bay that acquires a unique patina over time -- niche material, specific buyer.

    The case for it:
    Bronze case development is genuinely interesting and no two examples age the same way. For collectors who want a watch with a living surface.
    Consider instead if:
    Bronze patina is an acquired taste and the secondary market for bronze cases is thin. The steel refs hold value better.
    Open
  7. 7

    Sterling silver case Black Bay -- unusual material, premium price, heavy on the wrist.

    The case for it:
    If you want a silver-case tool watch, there is nothing else like this in production. Genuinely unusual and well-executed.
    Consider instead if:
    Silver cases scratch, tarnish, and require more maintenance than steel. The premium is hard to justify against the BB58 steel.
