The Tudor Pelagos FXD Ref. 25717N is a purpose-built 42mm titanium dive watch developed in collaboration with the French Navy’s elite combat swimmers, embodying the ultimate modern military tool watch with its distinctive fixed strap bars that ensure maximum security and reliability in the most demanding underwater operations. This professional-grade instrument features a lightweight yet incredibly robust grade 2 titanium case with a satin-brushed finish that minimizes light reflection, paired with a matte black dial that provides exceptional legibility through Tudor’s signature snowflake hands and luminescent hour markers. The unidirectional rotating bezel is crafted from titanium with a black ceramic insert and 60-minute graduation, specifically designed with an oversized profile for optimal grip even when wearing neoprene gloves during extended cold-water dives. At the heart of this horological marvel beats the in-house Manufacture Calibre MT5602, a COSC-certified chronometer that delivers robust precision with a 70-hour power reserve and silicon balance spring for superior anti-magnetic performance, ensuring the watch remains reliable throughout extended missions. Water-resistant to 200 meters with a titanium screw-down crown, this exceptional timepiece comes equipped with a forest green fabric strap featuring a red central thread and a self-gripping fastening system, alongside an additional black rubber strap included in the presentation box, offering versatility for both professional diving and everyday wear. The FXD nomenclature pays homage to its fixed strap bars, while the watch’s design lineage traces back to Tudor’s historic 1958 US Navy diver’s watches, making it a modern interpretation of the legendary “Milsub” with its pointed crown-guards and utilitarian aesthetic.
