Authenticate Tudor

Rolex's sister house, with its own movements now — and a vintage market full of replaced parts.

Founded 1926Geneva5 weighted checks

Tudor was founded by Rolex's Hans Wilsdorf to sell Rolex-cased watches at a lower price, which is exactly why its vintage market is complicated: many old Tudors sit in Rolex cases with Rolex crowns and Rolex bracelets, and telling a correct period-original watch from a later assembly is the real work.

Modern Tudor is a different proposition. Since 2015 the maison has made its own movements, and current production has its own case and bracelet identity. Counterfeits of the Black Bay exist and are generally poor.

The two reads that matter most are the movement — which should be what the reference specifies, whether an ETA base on older modern production or an in-house calibre on newer — and, on vintage, whether the case, dial, hands and bracelet all belong to the same period.

The maker's own mark

Reference and serial, and the Rolex inheritance

Tudor engraves its reference between the lugs at 12 and its serial between the lugs at 6, in the same manner Rolex used, and vintage Tudor cases are frequently stamped Rolex on the caseback and the crown because that is where they were made.

That inheritance is genuine and is not evidence of a fake. What it does mean is that vintage Tudor is assembled and reassembled freely, so the serial's era should agree with the dial's design, the hands' style and the bracelet's reference.

Modern production carries its own serials and a warranty card. No public lookup exists.

The checks

How Tudor is read

Ordered by how much each one settles. The decisive checks are the ones worth your first five minutes; the supporting ones only matter once those are clean.

01Decisive

Movement against reference

A Tudor reference specifies its calibre — a modified ETA base on much modern production, an in-house MT calibre on newer references. The movement inside must be that calibre. This usually requires opening the case, which is a watchmaker's job.

02Decisive

Period consistency on vintage

On a vintage Tudor, the case serial's era, the dial's design, the hand style and the bracelet's reference should all belong together. A snowflake-hand dial in a case from a decade that never had them is an assembly. This is the dominant problem in vintage Tudor and it is not counterfeiting.

03Strong

Dial printing and the rose or shield

Vintage Tudor used a rose logo, later a shield. Printing is sharp at magnification with correct spacing, and applied logos are level. Redialled vintage Tudors are common and show as printing that is slightly soft or spacing that is slightly wrong.

04Strong

Case and bracelet finishing

Modern Tudor cases are finished cleanly with defined boundaries between brushed and polished surfaces, and the bracelets are solid-link with a machined clasp. Hollow end links or a stamped clasp on modern production are failures.

05Supporting

Lume ageing on vintage

Lume on a vintage dial and on its hands was applied at the same time and should have aged to the same tone. A mismatch means replaced hands, which is honest servicing and a material fact.

Where a fake gives itself up

What a counterfeit pays for, and what it skips

Outright counterfeit Tudor is a smaller problem than at Rolex because the price point offers less margin, and the fakes that exist are usually crude. The real work in this maison is period consistency on vintage watches, where genuine parts from different decades are combined into watches that never left the factory that way.

A vintage Tudor with a service dial is genuine, correctly serviced, and worth substantially less than the same watch with its original dial. That is the distinction that matters here.

The failures worth looking for first

  • A dial design that does not belong to the case serial's era.
  • Snowflake hands on a reference that never had them.
  • A movement that is not the reference's specified calibre.
  • Bright hand lume against a patinated dial.

What we read for Tudor

Each of these is checked differently. The ones with their own page have enough that is specific to them to be worth reading separately.

The market

What Tudor does on the secondary market

Authenticity and value are separate questions, and answering the first is usually a step towards the second. These are broad ranges for honest, unrestored condition — an orientation, never an appraisal.

Ranges by line
LineResale as share of retailWhat moves it most
Black Bay, in-house movement60 – 85%Reference, bracelet, completeness

Broad international ranges. Vintage Tudor is priced on originality in a way modern Tudor is not.

Questions we are asked

Why does my Tudor say Rolex on the caseback?
Because Tudor was founded by Rolex to use Rolex cases, crowns and bracelets at a lower price. Rolex markings on a vintage Tudor are correct and original, not a counterfeit indicator.
How can I tell if a Black Bay is real?
Establish the reference first, then check that the movement matches it, the bezel is unidirectional with an even click, and the bracelet is solid-link with a machined clasp. The snowflake hour hand's square should be correctly proportioned with evenly filled lume.
Is a service dial a problem on a vintage Tudor?
It is genuine Tudor and correctly fitted, but it is worth substantially less to a collector than an original dial. Lume ageing across the dial and hands is how it is identified.
