Pre-owned watches trade across a wide condition spectrum. These ranges are typical for the secondary market.
The FXD-strap Pelagos launched with TUDOR's new generation and holds value well; titanium case and certified COSC movement justify the premium over earlier Pelagos references.
Editorial estimate, 2026 Q2. Actual prices vary by condition, date, and box/papers status.
The Pelagos FXD (ref. M25707B-0001) is the fixed-bar-lug Pelagos, 42mm titanium, the in-house MT5602 (no-date variant of the MT5612), and a case design developed with the Marine Nationale French combat-swimmer unit. The 'FXD' refers to the fixed strap-bars: no quick-release, no spring bars, just permanently-attached bars sized for the issued Marine Nationale strap. It is the most-tool-watch dive watch in Tudor's modern catalog.
Tudor announced the Pelagos FXD in 2021 as a Marine Nationale collaboration, a navy-blue-dialed titanium dive watch with fixed strap-bars (a design inherited from the 1970s Tudor 7016 'Marine Nationale' issued to the same unit). The MT5602 caliber is the chronometer-certified in-house Tudor movement without the date complication, a 70-hour reserve, free-sprung balance, silicon hairspring. The bezel is bidirectional (a navigation tool, not a dive-time bezel, significant because the FXD is designed for amphibious-navigation work, not recreational diving).
A black-dialed 'Pelagos FXD Chrono' followed; a 2023 'Pelagos FXD Alinghi' edition added a red bezel.
Common things to check: titanium case finishing (Tudor's titanium is unforgiving of polishing, most professional refinishing services will not touch a titanium FXD case, so original-finish examples are the canonical buy and scratched cases should be priced as condition-relevant rather than restorable); fixed strap-bars (the FXD ships with a Marine Nationale fabric strap and a rubber strap, verify both are included; aftermarket bracelets do not fit the FXD without modification, and the watch's design intent is the fabric or rubber strap); bidirectional bezel (correct on the FXD, it's a navigation bezel, not a dive-time bezel; if the bezel is unidirectional, it has been service-replaced incorrectly); MT5602 (in-house Tudor caliber, robust, no date complication); the watch is 42mm and 12.75mm thick, wears smaller than the original 42mm Pelagos because of the fixed-bar lug design.
Pelagos FXD examples trade in the $3,800-$4,300 range through 2024-2026, against a retail of approximately $4,400. The FXD has been one of the better-priced modern dive watches at the in-house caliber level; secondary-market supply has been consistent and pricing is steady. The 'Alinghi' and 'Chrono' variants trade at proportionally higher prices.
The fixed-bar lug design polarizes buyers, collectors who want strap-versatility prefer the standard 39mm Pelagos; collectors who want the tool-watch credentials of the Marine Nationale collaboration prefer the FXD.
The MT5602 is Tudor's in-house caliber and is serviced by Tudor's network and by experienced Rolex/Tudor independents, the same service story as the BB58 and the Pelagos 39. Service interval is 7-10 years; cost is moderate (low-four-figures via Tudor). Titanium case refinishing is not a routine service item; buyers should expect to live with the watch's accumulated wear rather than restoring it.

The fixed fabric strap attachment points are the defining physical feature; any Pelagos FXD with removable lugs or a bracelet has been modified.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Fixed lug attachment architecture | Fabric strap integrated into fixed lug points at 6 and 12; no spring bar slots or quick-release mechanism | Spring bar slots present or a standard bracelet fitted indicating lug modification |
| dial | GMT hand independent movement | Red arrow GMT hand advances in one-hour increments independently of the main hour hand via crown position | GMT hand that advances with the main hour hand simultaneously, indicating GMT complication failure |
| caseback | Cal. MT5602 in-house movement |
The Pelagos FXD is Tudor's military-specification dive watch, designed for combat divers who cannot risk a spring-bar failure during a dive. The fixed strap system with no spring bars is the defining feature. The titanium case and bezel keep the watch light on the wrist. Authentication priorities are the fixed strap attachment system, the titanium case construction, and the MT5602 movement.
