Tudor Pelagos FXD: The Ultimate Guide to the Military-Spec Diver You Need to Know

The Tool Watch, Reimagined.

In the world of luxury dive watches, few names carry the weight of real-world, military-grade credibility like the Tudor Pelagos. But within this celebrated family, one branch stands apart—a tougher, more purpose-built sibling forged in collaboration with elite naval forces. This is the Tudor Pelagos FXD collection.

Forget what you think you know about standard dive watches. The FXD isn’t just a watch with a military-inspired style; it’s a watch built with a military-spec philosophy. From its immovable strap bars to its unique bezel, every detail is a direct result of a mission-critical brief.

So, what exactly is the FXD? And which one is right for you? Let’s dive deep into the collection that redefined the modern tool watch.

What Makes an FXD… an FXD?

At first glance, an FXD looks like a Pelagos. But the magic is in the details, specifically the ones that set it apart from its standard, spring-bar-equipped brethren.

FXD = FiXeD Lugs: This is the headline feature. Instead of using removable spring bars to hold the strap, the case and lugs are milled from a single block of titanium, with the strap bars machined directly into the case. This makes the watch incredibly robust and virtually eliminates the risk of the watch head detaching from the strap. It’s a design born from a military requirement for ultimate security.

A Bezel for the Mission: The function of the FXD bezel changes with the model’s purpose, from countdown timers for underwater navigation to 24-hour scales for tracking time zones. Each is purpose-driven.

A Slimmer Profile: The FXD models are surprisingly slimmer than the standard Pelagos 42. This reduction in thickness makes them wear more comfortably on the wrist and slip under a cuff with ease, despite their rugged build.

The Collection: Every FXD Model Explained

The FXD collection has expanded from its singular, navy-blue origins. Here’s a breakdown of each model currently available.

1. The Original: Pelagos FXD “Marine Nationale” (Ref. M25707B)

This is the one that started it all. Developed in partnership with the elite Commando Hubert of the French Marine Nationale, this watch is a direct descendant of the Tudor Submariners that graced their wrists in the 1970s.

Dial Bezel: A deep, matte navy blue. The bezel is a bidirectional, fully graduated 60-minute countdown bezel, a specific request from French Navy combat swimmers for underwater navigation.

Case: 42mm satin-brushed titanium case with the signature fixed strap bars.

Strap: Comes with two straps—a navy blue fabric strap with a grey central thread and a single-piece rubber strap.

Best For: The purist. The watch enthusiast who values history, Best Quality ity, and the story behind the watch. This is the truest expression of the FXD philosophy.

2. The Tactical Operator: Pelagos FXD “US Navy” (Ref. M25717N)

While the blue FXD pays homage to Tudor’s past with the French, the black version is a nod to the brand’s history of supplying watches to the US Navy. It offers a more conventional, tactical aesthetic.

Dial Bezel: A matte black dial and a traditional unidirectional elapsed-time bezel. This makes it function more like a standard dive watch, appealing to a broader audience.

Case: The same 42mm titanium case with fixed lugs.

Strap: A forest green fabric strap with a red central stripe, offering a classic military look.

Best For: Those who love the FXD’s robust construction but prefer a classic dive watch functionality and a versatile, go-anywhere black-dial look.

3. The Globetrotting Operator: Pelagos FXD GMT

The latest evolution of the FXD platform adds one of the most useful complications for any world traveler or deployed professional: a GMT function. It takes the “operator” concept global.

Dial Bezel: This model features a matte black dial with a contrasting red “Pelagos” text and a red snowflake GMT hand for excellent legibility. The bidirectional bezel is marked with a 24-hour scale, allowing the tracking of up to three time zones simultaneously.

Movement: It’s powered by the Manufacture Calibre MT5652, a COSC-certified “true” or “flyer” GMT. This allows the main hour hand to be adjusted independently in one-hour jumps without stopping the watch, making it perfect for frequent travelers.

Case: The familiar and robust 42mm titanium case with fixed strap bars.

Best For: The frequent traveler, the military professional deployed abroad, or any enthusiast who needs a rock-solid, legible, multi-time-zone watch without sacrificing the unique FXD build.

4. On the Tarmac: Pelagos FXD Chrono “Cycling Edition” (Ref. M25827KN)

Marking the FXD’s first venture onto land, this model was designed in collaboration with the Tudor Pro Cycling Team. It adapts the lightweight chrono platform for the unique demands of professional cycling, featuring a specially calibrated scale for riders.

Dial Bezel: The key innovation is the fixed bezel’s tachymeter scale, which is recalibrated to match the speeds achieved by professional cyclists. The matte black dial features red accents for high-contrast legibility at a glance—a critical feature during a race.

Case: It uses the same 43mm case made from a high-tech matte black carbon composite, with the crown and pushers in titanium. This ensures the watch is incredibly light and durable, perfect for a sport where every gram counts.

Movement: It is powered by the same formidable Manufacture Calibre MT5813, a COSC-certified chronograph with a 70-hour power reserve.

Best For: Cycling enthusiasts, fans of motorsport timing, and collectors who appreciate Tudor’s expansion into new territories. It’s a hyper-specific tool watch for those passionate about two wheels.

5. Speed on the Water: Pelagos FXD Chrono “Alinghi Red Bull Racing Edition” (Ref. M25807KN)

Breaking the mold entirely, Tudor took the FXD concept from the depths of the ocean to the fast-paced world of professional yacht racing. This isn’t just a new colorway; it’s a completely different machine.

Dial Bezel: A stunning blue dial inspired by the Alinghi Red Bull Racing team colors, with red accents on the chronograph hands. It features a 60-minute countdown bezel, perfect for timing race starts.

Case: The real innovation is here. A 43mm case made from a high-tech matte black carbon composite, with the bezel, crown, and pushers in titanium. It’s incredibly lightweight and strong.

Movement: This model houses the Manufacture Calibre MT5813, a COSC-certified chronograph movement with a 70-hour power reserve.

Best For: The tech-forward enthusiast. This watch is for someone who appreciates cutting-edge materials, motorsport collaborations, and the added functionality of a chronograph. It’s the most modern and bold expression of the FXD.

Is the Pelagos FXD the Right Tudor For You?

The Tudor Pelagos FXD isn’t just another dive watch; it’s a statement. It’s for the person who values purpose over polish, function over frills.

Choose the FXD if: You love the idea of a watch with an Best Quality military heritage, demand ultimate durability, and appreciate a design where every single element has a reason to exist. The fixed lugs mean you’ll primarily wear it on single-pass fabric or rubber straps, giving it a distinct, rugged character.

Consider a standard Pelagos if: You want the flexibility of changing straps to bracelets, leather, or anything else. If you need a helium escape valve and the 500m water resistance (the FXD is rated to 200m) of the classic Pelagos 42, then the standard model might be a better fit.

Ultimately, the Pelagos FXD collection offers a unique proposition: a watch born from the needs of professionals, now available to all who dare to wear it. It’s a testament to Tudor’s commitment to building the best tool watches on the planet.
