The Tudor FXD was developed in close collaboration with the French Navy’s combat swimmers, making it a purpose-driven tool watch with genuine military pedigree. Its fixed strap bars—hence the “FXD” name—set it apart within the Pelagos lineup, offering enhanced durability and security for demanding underwater operations. Collectors prize this model not just for its modern engineering, but for its authentic connection to Tudor’s historic military commissions.

Reference 25707B/21 features a 42mm titanium case, blue dial, and bidirectional countdown bezel—details tailored to real-world mission use. The in-house MT5602 caliber delivers COSC-certified accuracy and a 70-hour power reserve, adding both reliability and value. Water resistance is rated to 200 meters, slightly less than the standard Pelagos, reflecting the unique case construction and intended operational depth.

Pricing varies based on condition, completeness (box, papers, original fabric strap), and production year—early runs and full sets command a premium. The FXD’s fixed lugs mean strap options are limited to pass-through styles, so consider your comfort preferences. Production numbers are not unlimited, and demand from both military history buffs and modern tool watch fans keeps the market active.

What owners love

  • The fixed strap bars make it uniquely robust for field and water use, setting it apart from other dive watches in this range.
  • The matte blue dial and bezel, with their distinctive shade and texture, are consistently praised as instantly recognizable and unlike typical blue divers.
  • The lightweight titanium case offers a comfortable, all-day wear experience that feels notably different from heavier steel alternatives.

Common Criticisms

  • The fixed lugs prevent use of standard two-piece straps, limiting strap options to pass-through styles only.
  • The 42mm case wears large and flat, causing fit issues for those with smaller wrists or preferring a more contoured caseback.
  • The bezel action is often described as feeling less precise and more muted compared to other Tudor dive models.
