Tudor Pelagos FXD 42mm MN21 25707B - 2021 Full Set
Marine Nationale Heritage in Fixed-Bar Titanium
The Pelagos FXD represents Tudor's collaboration with the French Navy (Marine Nationale)—stripping the standard Pelagos down to military specification with fixed spring bars, bidirectional bezel, and matte titanium construction. This 2021 MN21 edition delivers the brand's most purpose-built dive watch, designed to French combat-diver standards and built for real-world underwater deployment rather than desk-diving.
Specifications:
42mm titanium case (fully matte-finished, fixed spring bars)
Blue matte dial with applied luminous baton indices
Blue ceramic bezel insert (bidirectional rotating, 120-click)
Caliber MT5602 automatic movement (COSC chronometer, 70-hour power reserve)
Blue fabric NATO strap (MN-style elastic weave)
Additional blue rubber NATO strap included
Sapphire crystal, solid titanium caseback
200m water resistance (20 ATM)
Condition Assessment: Great pre-owned condition from 2021. Wear visible on case and clasp of fabric NATO strap—consistent with active use of a tool watch. Movement running at -3 seconds/day with 265+ amplitude (service history unknown but regulation excellent). This watch was clearly worn as intended—on NATO straps, in real-world conditions—but remains in strong working order with honest patina.
The Appeal: The FXD (Fixed) breaks from traditional dive-watch conventions with non-removable spring bars—forcing strap-only wear and eliminating bracelet options entirely. This isn't a limitation; it's Marine Nationale spec, designed for combat divers who need straps that can be adjusted over wetsuits instantly. The bidirectional bezel allows elapsed-time tracking in both directions (unconventional for civilian dive watches but military-practical). Matte titanium keeps weight minimal and eliminates reflective surfaces. COSC certification and 70-hour power reserve mean modern reliability backs the military aesthetic. This is Tudor's most uncompromising tool watch—built for function over wrist presence.
What's Included:
Watch on blue fabric NATO strap (MN-style)
Additional blue rubber NATO strap
2021 warranty card
Triple-boxed presentation (full MN packaging)
