Review: Tudor’s Pelagos FXD GMT Takes the Brand’s Military Roots From Sea to Sky

In the waters off the French coast, where Roman legions once stood guard along ancient shores, a different kind of maritime tradition was taking shape. Since the 1950s, Tudor has supplied the Marine Nationale with timepieces built for the most demanding underwater operations. But October 2024 marked a pivotal shift in this decades-long partnership; for the first time, Tudor looked to the skies.

The story behind this evolution begins with a problem that has plagued military operators for generations: watch loss in critical situations. Traditional spring bars, no matter how robust, remain a potential failure point. Tudor looked to the past for a solution, taking inspiration from military watches of yesteryear by eliminating spring bars entirely. The FXD designation stands for “FiXeD strap bars,” referencing the integrated titanium bars machined directly into the case that make strap separation physically impossible.

This fixed-lug system debuted in 2021 with the original blue-dialed Marine Nationale collaboration, and the Tudor Pelagos FXD GMT represents the platform’s evolution from purely aquatic missions to aviation operations. Built specifically for the Aéronautique Navale, this watch serves pilots crossing time zones at altitude rather than divers navigating by dead reckoning underwater. 

After months of wearing this watch on a regular basis, we figured the 1-year anniversary felt like a great time to revisit the Tudor Pelagos FXD GMT Zulu Time, and share our thoughts. So without further ado, let’s get into it.

Admittedly, we were already huge fans of the FXD GMT before ever getting the chance to see it in person — and our initial first impression of the watch was, this thing absolutely delivers. The beige-toned luminous material that sparked countless forum debates about “fauxtina” reads completely differently under natural light. Rather than appearing aged or vintage-inspired, the warm tone creates visual harmony with the military green fabric strap and matte titanium case.

The bright orange GMT hand immediately catches the eye, a detail that inevitably recalls the Explorer II’s famous accent color. Yet in the Pelagos FXD GMT, it feels unmistakably Tudor — integrated into a case and dial language that’s rugged, matte, and almost mission-driven. The choice also really highlights Tudor’s evolution as a brand: once seen as Rolex’s quieter sibling, today Tudor confidently leans into shared design cues while continuing to add their unique functionality to the mix — like a 48-click bezel that can track tricky 30-minute offset time zones.

At 42mm wide with a 52mm lug-to-lug measurement, this watch mirrors the standard FXD dimensions. On paper, these numbers seem daunting, but the fixed-lug construction creates an optical illusion. The strap passes directly through the integrated bars, eliminating the visual break that traditional spring bars create and making the case appear to flow seamlessly into the strap.

And let’s talk about the thickness for a moment. The 12.7mm thickness is exactly what we’d expect from a modern-day GMT at this price point. It’s a 2mm reduction from the Black Bay Pro we recently reviewed, which uses the same MT5652 caliber, showcasing Tudor’s evolving case construction expertise.

The 42mm Grade 2 titanium case maintains the FXD’s distinctive architecture while still accommodating GMT functionality in that slim 12.7mm profile (seen on our wearer’s 6.75” wrist for reference). The brushed finish provides the matte, non-reflective surface that military specifications demand, while the Grade 5 titanium caseback offers superior durability for movement mounting points.

Tudor’s choice of Grade 2 titanium has sparked debate among enthusiasts who argue Grade 5 offers superior scratch resistance. However, this decision reflects practical military requirements. Grade 2 provides the ideal balance of weight reduction, corrosion resistance, and the non-reflective finish essential for tactical operations. The darker, more matte appearance also integrates better with the overall aesthetic than the brighter Grade 5 finish would provide.

Those integrated titanium bars that give the FXD its name represent more than just a security feature. They allow Tudor to create a slimmer overall profile since the case doesn’t need to accommodate traditional spring bar holes and their associated structural reinforcement. The bars themselves are machined as part of the case, creating a connection stronger than the strap material itself.

The bidirectional rotating bezel operates with 48 clicks, providing precise half-hour adjustments crucial for tracking time zones with 30-minute offsets like India, Australia’s Northern Territory, or Newfoundland. 

The ceramic bezel insert displays a fully luminous 24-hour scale in the same beige tone as the dial markers, creating visual continuity while still providing solid nighttime functionality. The bezel action feels precise, with enough resistance to prevent accidental rotation, and still remaining easy to operate with gloves.

The signed, screw-down titanium crown provides 200m of water resistance, maintaining the Pelagos heritage even in this aviation-focused variant. The crown guards integrate seamlessly into the case sides, and the  “M.N.25” inscription across the caseback — short for Marine Nationale 2025 — rounds out the affair.

Underneath a flat sapphire crystal, the matte black dial serves as the foundation for exceptional legibility. Applied hour markers paired with Tudor’s signature snowflake hands provide instant brand recognition, while their oversized shapes ensure exceptional legibility in challenging conditions

The dial uses a thoughtful dual-color luminous treatment: blue lume for local time elements — hour markers, hour and minute hands, and running seconds — and green lume for the GMT hand tip and bezel numerals. This color coding makes it instantly clear which time zone you’re reading, even in total darkness. And we must say, the lume brightness is impressive to say the least — and this thing glows for quite some time. Not surprising considering its military roots.

The beige coloring of the luminous material has been a topic of discussion among enthusiasts, but as we’ve mentioned, we quite like it in person. And we understand the utility here. Instead of the stark white lume paint often seen on tool watches, Tudor chose a muted beige that gives the watch a more tactical, less reflective look in daylight – and one that still delivers strong legibility once the lights go out.

Typography across the dial maintains military precision. “PELAGOS GMT” appears in orange, matching the GMT hand, while “Master Chronometer” and the depth rating use crisp white printing. The orange GMT hand features an arrow-shaped tip that clearly distinguishes it from the traditional snowflake hour hand. And the date window at 3 o’clock features a beige background matching the hour markers, creating some nice visual cohesion to round out the look.

Underneath the hood, the MT5652-U movement represents Tudor’s commitment to chronometric excellence in military applications. The “U” designation indicates METAS Master Chronometer certification, making this the first FXD model to achieve this standard — testing the complete watch rather than just movements.

The movement provides true GMT functionality, allowing independent adjustment of the local hour hand in one-hour increments without stopping the seconds hand or affecting the GMT hand position.

Power reserve reaches 65 hours, which is slightly reduced from the standard 70-hour specification found in other MT5652 applications. We imagine this reduction results from the tighter chronometric standards required for Master Chronometer certification, which ensures accuracy throughout the stated power reserve duration.

The silicon hairspring provides enhanced magnetic resistance beyond the METAS requirements, while the variable inertia balance wheel contributes to long-term accuracy stability. These features combine to create a movement that maintains precision in the electromagnetic environments common around modern aircraft systems.

The 28-jewel movement beats at 28,800 vibrations per hour, and the automatic winding system uses Tudor’s proven bidirectional rotor design for efficient power generation during normal wear.

The green fabric strap represents a departure from the hook-and-loop fastening systems used on previous FXD models. The single-pass construction with traditional pin buckle provides a more refined appearance while still maintaining the security advantages of the fixed-lug system.

On the wrist, the strap material feels substantial and strong, while still being comfortable at the same time. It’s a tight weave to help combat fraying and water absorption. All of these hardware here uses matching Grade 2 titanium, maintaining weight savings while also providing corrosion resistance in marine environments.

The removable fabric keeper is a really cool military touch, displaying the Aéronautique Navale, roundel. This detail can be removed or flipped to hide the military insignia for civilian wear, addressing the very valid concerns about wearing military markings without service connection.

The 22mm width tapers slightly through its length, creating a nicely balanced appearance on the wrist. The pin buckle system offers multiple adjustment holes for precise fit, though it does lack the infinite adjustability of previous velcro systems. The trade-off provides a more polished appearance that’s more suitable for daily wear rather than just pure military use.

Ok, so after months of living with this military timepiece, we once again ask the question, is the Tudor Pelagos FXD GMT Zulu Time worth it?

That question is a bit nuanced here. The FXD GMT is a military tool watch in the truest sense. It doesn’t masquerade as a luxury piece or pretend to be a boardroom-friendly GMT; it wears its utilitarian DNA proudly. Fixed lugs, matte surfaces, oversized markers, and that mission-driven beige lume make this watch unapologetically functional.

And that approach won’t resonate with everyone, and Tudor knows it. If you’re seeking versatility that transitions from the outdoors to the office, or need something that disappears under a dress shirt cuff, Tudor makes plenty of other excellent options. The Black Bay 58 GMT offers similar functionality in a more socially acceptable package, while the Pelagos 39 delivers titanium refinement with traditional bracelet flexibility.

But here’s the thing — if you’re drawn to watches that feel truly purpose-built, where every design choice stems from real-world military requirements rather than focus group feedback, it’s really hard to beat the FXD GMT. This watch exists because French naval aviators needed something specific, not because Tudor’s marketing department identified a market gap.

At just under $5,000, the value proposition is justified through and through. You’re getting Master Chronometer certification, a true GMT movement, titanium construction, and authentic military provenance from one of the most storied partnerships in horology. Can you find similar specs elsewhere for less money? Perhaps. Will you find this combination of authenticity, functionality, and build quality? Doubtful.

So the real question here isn’t whether it’s worth the money — it’s whether you connect with what this watch represents.
