Hans Wilsdorf founded Tudor in 1926 and relaunched it in 1946 explicitly as the affordable Rolex: Rolex cases and bracelets, bought-in movements, a lower price. That relationship has changed, but the question it raises has not. Here is a straight answer.
The historical relationship

For decades a Tudor Submariner was a Rolex Oyster case, a Rolex Oyster bracelet and a Rolex crown, with an ETA movement inside instead of a Rolex calibre. The reference 7016, 7021 and 9411 "Snowflake" Submariners are genuine collectables today and were sold to the French and US navies.
That is why vintage Tudor has appreciated so sharply: it is, structurally, a Rolex.
What changed
Tudor withdrew from many markets in the 1990s and relaunched globally in 2010 with the Heritage and Black Bay lines. In 2015 it began fitting its own in-house MT56xx calibres — COSC-certified, 70-hour reserve, silicon hairspring — which are genuinely excellent movements.
Modern Tudor no longer uses Rolex cases. It is a separate manufacture with a shared parent.
What you get for the money
A Black Bay Fifty-Eight is a 39mm dive watch with an in-house chronometer movement, a bronze or steel case and a genuinely good bracelet, at roughly a third of what a Submariner costs. On specification alone it is the better buy and it is not close.
The Pelagos, in titanium with a helium valve, is a more capable dive watch than a Submariner by any technical measure.
What Rolex gives you that Tudor does not
Liquidity and recognition. A steel Rolex sports watch can be sold in any major city in an afternoon at a price you can predict. A Tudor sells more slowly and at a wider spread.
And value retention. Modern Tudor depreciates meaningfully from retail; Rolex generally does not. Bought pre-owned that gap narrows, but it does not close.
The vintage Tudor exception
Vintage Tudor — Snowflake Submariners, Monte Carlo chronographs, Oyster Prince Submariners — has performed extraordinarily well and now trades at prices that would once have bought a Rolex.
If you are buying to hold, vintage Tudor is a far more interesting proposition than modern Tudor.
How we would decide
If this is your only watch and you may need to sell it, buy Rolex. Our collection starts at £3,070. If you are buying a second or third watch to wear and enjoy without thinking about resale, modern Tudor is arguably the best value in Swiss watchmaking.
And if you want a watch with genuine collector interest at an accessible price, buy a vintage Tudor Submariner and hold it.
