Tudor Pelagos FXD 42mm 25707B

Overview 

The Tudor Pelagos FXD 25707B is a professional-grade dive watch developed in collaboration with the French Navy (Marine Nationale) for military underwater navigation. Released in 2021, it takes a specialized approach to durability and precision, distinguishing itself from the standard Pelagos models. The 42mm titanium case is lightweight yet incredibly robust, ensuring comfort during extended wear. One of its standout features is the fixed (FXD) lugs, which enhance security by eliminating the risk of spring bar failure—an essential consideration for military divers operating in extreme conditions.

The matte blue dial and bezel, a signature Marine Nationale color, contribute to the watch’s bold yet highly legible appearance. Unlike the standard Pelagos, the FXD features a bi-directional rotating bezel with a 120-click mechanism, optimized for underwater navigation rather than traditional dive timing. The fully graduated ceramic bezel insert, combined with the Snowflake hands and applied markers, is filled with Grade X1 Swiss Super-LumiNova, ensuring exceptional visibility in low-light or murky conditions.

Powering the Pelagos FXD is the Tudor Manufacture Calibre MT5602, a COSC-certified automatic movement with a 70-hour power reserve. Built for resilience, it features a silicon balance spring, providing excellent resistance to shocks and magnetic fields. With a 200m water resistance, the FXD prioritizes military navigation over deep-sea exploration, forgoing the helium escape valve found in standard Pelagos models. This makes it a refined tool for professionals who require precision and reliability in shallow-water operations.

For versatility, the Pelagos FXD comes with both a single-piece fabric strap and a blue rubber strap, each designed for flexibility, comfort, and durability. The fabric strap ensures a secure fit, while the rubber strap offers a sportier alternative for daily wear. The Tudor Pelagos FXD 25707B is a fusion of military heritage and modern innovation, making it a compelling choice for both professional divers and enthusiasts drawn to its stealthy yet functional aesthetic.
