Overview

The Tudor Pelagos FXD ref. 25707B is a purpose-driven dive watch that strips the Pelagos formula back to its operational essentials. Its 42 mm titanium case is fitted with fixed strap bars — the "FXD" designation — eliminating the standard spring-bar system in favour of a more secure, military-influenced attachment. A matte navy blue dial and the in-house Cal. MT5602 movement complete a specification aimed squarely at function over flourish.

History

The Pelagos FXD emerged from Tudor's ongoing relationship with professional and military diving communities, drawing on the brand's long history of supplying robust tool watches to naval forces. Introduced in 2021, the FXD variant distinguished itself within the broader Pelagos family by adopting fixed strap lugs — a configuration historically associated with military-issue dive watches, where strap security under operational conditions is paramount. The reference 25707B represents Tudor's commitment to developing in-house movements, the Cal. MT5602 having been a cornerstone of the modern Pelagos line since its introduction. The model has since become a focal point for collectors drawn to the intersection of heritage tool-watch design and contemporary manufacture.

Notable points

Fixed strap bars (the "FXD" hallmark) replace conventional spring bars, providing a more secure strap attachment rooted in military dive-watch tradition.
The 42 mm case is crafted from lightweight titanium, reducing wrist fatigue during extended wear without sacrificing structural integrity.
Cal. MT5602 is an in-house Tudor movement, offering a 70-hour power reserve and COSC-level chronometric performance.
The matte navy blue dial minimises glare and enhances legibility in low-visibility underwater environments.
Introduced in 2021, the Pelagos FXD marked a distinct sub-variant within the Pelagos family, appealing to collectors who prioritise operational authenticity alongside modern manufacture credentials.
