The FXD is a family, not a single specification. A standard titanium FXD, an Alinghi carbon edition and the FXD Chrono are genuinely different watches — so identifying exactly which one you own comes first.

The short answer
The Tudor Pelagos FXD is defined by its fixed strap bars — machined into the case rather than conventional spring bars — so it wears on a single pass-through strap and takes no bracelet. The standard time-only FXD is a 42mm grade-2 titanium diver — no date, 200m water resistance, in-house calibre MT5602 — with a rotating bezel whose configuration is reference-specific: bidirectional countdown/navigation on the blue Marine Nationale reference, and a unidirectional 60-minute dive bezel on the black M25717N. The line was developed with the French Navy's combat swimmers, and the blue dial is the reference most associated with that Marine Nationale heritage. But the FXD Chrono is a different watch — a 43mm carbon composite chronograph with a date and 100m water resistance — so identifying exactly which FXD you own comes first. Fair Vintage confirms the reference from the watch, grades the condition, values the straps, 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.
Every Pelagos FXD shares one defining feature: fixed strap bars, machined directly into the case in place of conventional spring bars. That means the watch takes a single pass-through fabric or rubber strap and cannot be fitted with a bracelet — the clearest way to confirm you have an FXD rather than a standard Pelagos. Beyond that, the FXD line has diverged into genuinely different watches, so the next step is confirming the exact reference.
The standard time-only FXD is a 42mm grade-2 titanium case with fixed bars, a no-date dial with snowflake hands, 200m water resistance and the in-house calibre MT5602 (COSC, roughly a 70-hour power reserve). One thing is not shared across the time-only references: the bezel. The blue Marine Nationale reference has a bidirectional countdown/navigation bezel; the black M25717N has a unidirectional 60-minute dive bezel. So the bezel is part of identifying the exact reference, not a family-wide constant.
The FXD is best understood as a small family. The features below are what actually separate the references — and why we identify yours precisely before valuing it.
The original 2021 FXD. 42mm titanium, fixed bars, no-date, 200m, MT5602 — with a bidirectional countdown/navigation bezel developed for the underwater-navigation needs of French Navy combat swimmers. The blue dial is the reference most associated with that Marine Nationale development.
A black-dial titanium FXD — same 42mm case, fixed bars, MT5602, no-date and 200m — but with a unidirectional 60-minute dive bezel (titanium with a ceramic disc), not the blue MN's bidirectional navigation bezel. Supplied on a green-and-red fabric strap with an additional rubber strap.
Still time-only, but with a black carbon composite case rather than titanium. A useful reminder that "carbon" does not automatically mean "chronograph." Confirmed from the reference.
A materially different watch — see the section below. Do not assume it shares the standard FXD's case material, size, movement, bezel or water resistance.
The FXD Chrono looks related, but it is a separate design and is valued separately. Treating it as "an FXD with a chronograph" gets the specification wrong.
42mm grade-2 titanium · fixed strap bars · no date · 200m water resistance · time-only calibre MT5602 · bezel is reference-specific (bidirectional countdown/navigation on the blue MN; unidirectional 60-minute dive on the black M25717N).
43mm black carbon composite case · fixed (non-rotating) bezel · date at 6 o'clock · 100m water resistance · chronograph calibre MT5813 · domed sapphire, cycling-focused design.
Case material, size, movement, bezel and water resistance all differ between the standard FXD and the FXD Chrono. Sending the reference number, or a clear photo of the caseback and dial, lets us value the exact watch rather than a generic "Pelagos FXD."
The reference and configuration come first — a titanium time-only FXD, a carbon edition and the FXD Chrono are assessed on their own terms. After that, condition and completeness shape the offer.
Certain configurations — the Marine Nationale-associated blue dial, or limited editions — can attract a distinct enthusiast audience, which may influence buyer demand. Reference and condition remain the basis of the valuation.
Because the FXD wears exclusively on pass-through straps, the original fabric strap (and any additional rubber strap) is worth keeping with the watch. On titanium references, the case finish is graded carefully; on carbon references, the composite case is assessed for edge chips and wear. The bezel — rotating on the standard FXD (bidirectional countdown/navigation on the blue MN, unidirectional 60-minute dive on the black M25717N) and fixed on the Chrono — is checked for action and insert condition.
Buyers like to see the warranty card, box and booklets, and the original straps. None of these are essential to sell. We confirm the exact FXD reference from the watch itself and reflect any missing items in the offer — you do not need the full set to get a fair valuation.
Send the reference and photos for a free, no-obligation valuation. If it works for you, we provide a free, fully insured Royal Mail Special Delivery label, check the watch, and pay by bank transfer within 72 hours of acceptance — everything by post from Bedfordshire.
Getting the reference right — titanium or carbon, time-only or chronograph — means your watch is valued as the specific FXD it is. For more on what shapes an offer, see our guide to what actually makes a watch valuable.
Most buyers treat the FXD as a single watch. It isn't. Confirming whether yours is a titanium time-only reference, a carbon edition or the FXD Chrono — and grading the case, bezel and straps accordingly — is the difference between a generic figure and a valuation that reflects exactly what you own.
Reference confirmed. Titanium or carbon graded honestly. Straps, box and papers valued. Free insured postage both ways. No obligation — we return your watch free if you decline the offer.

The FXD has fixed strap bars machined into the case instead of conventional spring bars, so it takes a single pass-through fabric or rubber strap and cannot be fitted with a bracelet. That fixed-bar construction is the defining FXD identifier.
Is my FXD titanium or carbon composite?
The standard time-only FXD has a 42mm grade-2 titanium case. Some editions — including the Alinghi Red Bull Racing FXD and the FXD Chrono — use a black carbon composite case instead. Case material affects identification and valuation, so we confirm it from the watch and its reference.
Is the FXD Chrono the same watch as the standard FXD?
No. The FXD Chrono is a materially different watch: a 43mm carbon composite case, 100m water resistance, a fixed (non-rotating) bezel, a date, and the chronograph calibre MT5813. The standard FXD is 42mm titanium, 200m, has a rotating bezel (not fixed) and no date, and runs the time-only MT5602. We value them separately.
Does the Pelagos FXD have a date?
The standard time-only FXD is a no-date watch, showing hours, minutes and seconds only, powered by the MT5602. The FXD Chrono does carry a date, at 6 o'clock. Identifying which one you own matters for an accurate valuation.
What is the Marine Nationale connection?
The Pelagos FXD was developed with the French Navy's combat swimmers (the Marine Nationale), and the blue-dial reference is the one most associated with that heritage. It informs how the model is identified and described, but the watch is valued on its reference and condition, not on the association alone.
Can I sell the FXD without its original fabric strap or box and papers?
Yes. The original single-pass fabric strap and any additional rubber strap are worth keeping with the watch, and the warranty card and box help, but they are not essential. We confirm the reference from the watch and reflect any missing items in the offer.
How is the FXD different from the Pelagos 39?
The Pelagos 39 is a 39mm titanium diver on a conventional bracelet with normal spring bars, a unidirectional dive bezel and no helium valve. The FXD is 42mm with fixed strap bars and a military-derived design; its bezel depends on the reference (bidirectional countdown/navigation on the blue Marine Nationale, unidirectional dive on the black M25717N). They are separate models — we value each as what it is.
What should I send for a valuation?
Clear photos of the dial, the caseback, the reference and serial where visible, the fixed strap bars, the bezel, and any straps, box and warranty card. That lets us confirm the exact FXD reference and grade condition before giving a free, no-obligation valuation.
