Tudor Pelagos FXD Black 25717N

The Tudor Pelagos FXD Black Ref. 25717N is a purpose-built, professional-grade dive watch that channels Tudor’s deep heritage in military-spec dive instruments while bringing modern materials and movement technology to the forefront. At its core is a 42 mm satin-brushed titanium case with fixed strap bars machined directly into the case—a design nod to mid-century military “MilSub” specifications that enhances robustness and reliability for serious underwater use. The matte black dial features Tudor’s signature “Snowflake” hands and bold luminous indices for excellent legibility, paired with a unidirectional rotating bezel with a ceramic insert and 60-minute graduation that meets ISO6425 diver standards. Water resistance is rated to 200 m (660 ft), making the FXD perfectly capable for everyday wear and recreational diving alike.

Inside beats Tudor’s in-house Manufacture Calibre MT5602, a COSC-certified automatic movement with a 70-hour power reserve, silicon hairspring, and robust construction ready for daily use and adventuring. Unlike many modern divers with conventional spring bars, the fixed bars make this watch true to its military-inspired roots and ideal for secure strap attachment. The Pelagos FXD 25717N typically comes on a forest-green one-piece fabric strap with a red central stripe and self-gripping fastening system, harking back to vintage military webbing, and also includes a black rubber strap with fabric motif for versatility. As a modern interpretation of Tudor’s military dive legacy, the FXD offers a compelling mix of tool-watch functionality, historical influence, and contemporary precision.

Tudor was established in 1926 by Hans Wilsdorf, the founder of Rolex, with a vision to create watches that offered the same reliability and precision as Rolex, but at a more accessible price point. Built with robust Swiss movements and housed in Rolex-quality cases, Tudor quickly earned a reputation for producing tool watches trusted by military units and professional divers around the world. In the 1950s and ‘60s, Tudor introduced iconic models like the Oyster Prince Submariner, worn by the French Navy, and carved out a legacy as a maker of rugged, no-nonsense timepieces built to perform under extreme conditions.

In recent years, Tudor has reemerged as one of the most exciting names in modern watchmaking. Collections like the Black Bay, Pelagos, and Ranger pay homage to the brand’s vintage roots while incorporating in-house calibers and contemporary design updates. The Black Bay Fifty-Eight, in particular, has become a collector favorite for its perfect blend of vintage proportions and modern engineering. With a design language all its own and a renewed focus on manufacturing independence, Tudor has established itself as far more than Rolex’s younger sibling—it’s a brand that balances heritage, innovation, and value with serious horological credibility.
