The Pelagos 39 brought Tudor's serious titanium diver down to a more wearable size. Its specification is quite specific — and often misunderstood — so it pays to get the details right.

The short answer
The Tudor Pelagos 39 is reference 25407N: a 39mm grade-2 titanium case with a satin finish, 200m water resistance, a ceramic bezel insert, and Tudor's in-house calibre MT5400 (COSC, roughly 70-hour power reserve). Importantly, it is a no-date watch — hours, minutes and seconds only — and it has no helium escape valve. It's distinct from the larger Pelagos 42, the left-hand-drive Pelagos LHD and the Pelagos FXD. Fair Vintage confirms the 25407N from the watch, grades the condition, values the box and papers, and gives a free, no-obligation valuation — all by post from Bedfordshire, with insured postage and payment by bank transfer within 72 hours of you accepting.
The Pelagos 39 is reference 25407N: a 39mm grade-2 titanium case with a satin finish, 200m water resistance, a ceramic bezel insert, and Tudor's in-house calibre MT5400 (COSC, roughly 70-hour power reserve). Importantly, it is a no-date watch — the dial and movement show hours, minutes and seconds only, with no date window. It also has no helium escape valve.
The Pelagos 39 is distinct from its stablemates. The 39 stands apart precisely because of its 39mm titanium case, no-date dial and pared-back diving specification.
39mm titanium, 200m, ceramic bezel, in-house MT5400. No date, no helium escape valve.
Larger, rated to 500m, has a helium escape valve, and includes a date.
A left-hand-drive 42mm variant with a date — a separate model from the 39.
A fixed-strap-bar model of different specification — 42mm, military-derived, with a reference-specific bezel. If that's your watch, see sell your Pelagos FXD.
Condition of the titanium case and bracelet (titanium shows wear differently from steel), the ceramic bezel, whether the clasp and bracelet are complete, and the set. Its no-date, cleaner-dial character is part of the appeal for many buyers.
Get the specification right before you sell. The Pelagos 39 is a no-date, 39mm titanium diver with no helium valve, powered by the MT5400 — distinct from the Pelagos 42. Valuing it as the specific model it is means it isn't confused with a date-equipped 500m sibling.
Buyers like the warranty card, the box and booklets, the original titanium bracelet with all links, and any additional rubber strap supplied. Because the bracelet is titanium and specific to the model, having all the links is worthwhile.

What's the difference between the Pelagos 39 and the Pelagos 42?
The 39 is 39mm titanium, 200m, no date and no helium valve; the 42 is larger, rated to 500m, has a helium escape valve and a date.
What movement does it use?
Tudor's in-house calibre MT5400, COSC-certified, with roughly a 70-hour power reserve.
Does titanium condition affect the value?
Yes — titanium marks differently from steel, so the condition of the case and bracelet is assessed carefully.
Does it have a helium escape valve?
No — unlike the Pelagos 42, the Pelagos 39 has no helium escape valve.
Is this the same as the Pelagos FXD?
No — the FXD is a separate fixed-strap-bar model with a different specification.
