The Black Bay 58 and Black Bay 54 are two of the most recognisable watches in Tudor's modern catalogue, and both have a strong, steady following among UK buyers. The two references are valued quite differently, so it helps to be precise about which one you have.

The short answer
To sell a Tudor Black Bay 58 or Black Bay 54, identify the exact reference first — they are different watches. The Black Bay 58 is 39mm with the in-house calibre MT5402 (79030N black, 79030B navy); the Black Bay 54 is 37mm with the calibre MT5400 (79000N). Fair Vintage confirms the reference from the watch, grades the case, bezel and bracelet, values the box and papers, and gives a free, no-obligation valuation. Everything is done by post from Bedfordshire, with fully insured postage and payment by bank transfer within 72 hours of you accepting.
The Black Bay 58 and Black Bay 54 look related but are distinct references with their own case sizes, movements and heritage. The single most useful step before selling is being clear about which you own — it isn't simply "a Black Bay."
Launched in 2018 with a 39mm steel case, 200m water resistance and the in-house calibre MT5402 (COSC, roughly 70-hour power reserve). The name nods to 1958 and Tudor's reference 7924. The 79030N has a black dial and bezel; the 79030B, added in 2020, is navy blue.
Introduced in 2023 at 37mm with 200m water resistance and the calibre MT5400 (COSC, roughly 70-hour power reserve). Its proportions and name draw from Tudor's reference 7922 of 1954. It is not a smaller Black Bay 58 — case size, movement and heritage reference are all specific to the 54.
The sterling-silver Black Bay 58 925 and the Black Bay 58 Bronze sit apart from the steel models. They are distinct references and are valued separately from the steel 79030N and 79030B.
Send us clear photographs of the dial, caseback and any paperwork and we will confirm the exact reference — 79030N, 79030B or 79000N — before you send anything. The case size and movement tell us which watch it is.
Condition of the case and bezel, whether the watch has been polished, the completeness of the set, and current buyer appetite for the specific dial colour all play a part. The navy 79030B and the newer 79000N each attract their own audience, so we assess your exact reference rather than treating "a Black Bay" as one thing.
Do spare bracelet links matter? Yes — they let the bracelet be resized for the next owner, so it is worth including any you have, along with any fabric or leather strap that came with the watch alongside the bracelet.
For a Tudor of this era, buyers generally like to see the warranty card, the box and booklets, and any spare bracelet links so the bracelet can be resized to a new wrist. If yours came on a fabric or leather strap as well as the bracelet, including both helps. A missing card doesn't stop a sale — it's simply one factor in the offer.
Plenty of owners have long since put the packaging aside. We still buy Black Bay 58s and 54s without the full set; we'll confirm the reference from the watch itself and factor the missing items into the valuation transparently.
Tell us the reference and condition and we'll give you a free, no-obligation valuation. If it works for you, we send a free, fully insured Royal Mail Special Delivery label, check the watch on arrival, and once you accept the offer we pay by bank transfer within 72 hours. Everything is done by post from our Bedfordshire base — there's nothing to arrange in person.
A buyer who knows the difference between an MT5400 and an MT5402, and between 1954 and 1958 heritage, prices your watch on what it actually is. That tends to make for a straighter, quicker conversation than a general jeweller who values by brand alone.

The 58 is 39mm with the MT5402 movement (2018, reference 7924 heritage); the 54 is 37mm with the MT5400 (2023, reference 7922 heritage). Different sizes, movements and history.
Is the navy 79030B worth more than the black 79030N?
They appeal to different buyers; we value each on its own condition and current demand rather than assuming one is always higher.
Do you buy the Black Bay 58 Bronze or 925?
Yes, though those are distinct references from the steel models and are valued separately.
Can I sell my Black Bay 54 without the box and card?
Yes. We confirm the 79000N from the watch and reflect any missing items in the offer.
Does a polished case reduce the value?
It can, depending on how much metal has been removed and how sharp the bevels remain. We assess this individually.
Do spare bracelet links matter?
They help — they let the bracelet be sized for the next owner, so it's worth including any you have.
