Laco Frankfurt 40 GMT Review: Pforzheim Pilot GMT, Downsized
Same Pforzheim Pilot GMT, but downsized
Every so often a brand goes back to one of its best selling models and does the one thing collectors have been quietly asking for the whole time. Not a new dial variant, not a limited edition, not a colour drop. Just a properly considered downsize that keeps the entire design brief intact. The new Laco Frankfurt 40 GMT is exactly that release, a compact 40 millimetre reinterpretation of a Red Dot winning pilot GMT that has been sitting at 43 millimetres for years. If you like the Frankfurt GMT but your wrist has always been on the edge of the original, this is the version you have been waiting for.
Laco are the Pforzheim based German house that has been making watches since 1925, which means they are quietly celebrating their centenary this year. The brand’s flieger DNA runs deep. In the 1940s Laco produced observation watches at 55 millimetres, developed to strict military specifications for aerial navigation, and that lineage is still visible in almost every current pilot reference in the catalogue. The modern collection covers classic and modern fliegers, tool watches, and chronographs, and the Frankfurt line has quietly become one of the more thoughtful modern pilot GMT executions on the market (a segment that is otherwise dominated by either serious luxury pricing or workshop level tool grade compromises).
The Frankfurt 40 GMT launches on July 9 2026 and comes in two dial variants. The classic matte black (reference 862187) leans hardest into the traditional pilot watch language, and the matte grey (reference 862188) reads as a more contemporary almost monochromatic take. Both share every other specification and both retail at $2,220 / €1,850. Neither is limited. Both come as a full set that includes an extra strap, a keychain, and a strap changing tool (more about this soon, but the presentation is 100/10).
Case, Character and Cockpit Restraint
The case is the piece where the downsize decision actually pays off. The Frankfurt 40 GMT sits at 40 millimetres in diameter with a 20 millimetre lug width and weighs approximately 82 grams. The material is stainless steel with a dark sandblasted finish that reduces reflections and reinforces the tool watch character in the way most modern pilot cases only pretend to. Water resistance is a serious 20 ATM (200 metres), which is well above what a pilot watch actually needs but exactly right for a piece that is going to see everyday wear.
Underneath the surface work, Laco have specified magnetic field protection, which is a properly considered feature for anyone who spends real time in aircraft cabins, hospitals, or the increasingly magnetised environment of daily life. The caseback is closed with an airplane relief engraved into it, and the two crowns (one for time setting, one for the internal bezel adjustment, both protected and screwed down) sit at three o'clock in a stacked configuration that has been part of the Frankfurt GMT since its original introduction. A double-domed sapphire crystal with anti-reflective coating on both sides sits over the dial, keeping legibility clean at almost any angle (and yes, it holds the light beautifully across the crown side).
On paper this is a 40 by 200 metre pilot GMT with magnetic protection. In reality it is a properly wearable daily piece that punches well above its weight class. The numbers translate into a watch that disappears in terms of comfort but never in terms of presence.
A Dial Built for Quick Reading
The dial is the beating heart of any flieger and the Frankfurt 40 GMT gets the balance exactly right. Both variants use a matte finished dial with clear Arabic numerals and applied indices coated in Super-LumiNova C3. The hour and minute hands are thermally blued with a lume fill, which gives them the kind of visual pop that flat black hands cannot match, and the seconds hand carries a small stylised aircraft near the tip that has become a Frankfurt GMT signature. The GMT hand is finished in Super-LumiNova Orange at the tip, which is the exact colour choice you want on a second time zone hand because it never gets confused with the local time indicator.
The black variant leans into the classic pilot watch reading, with high contrast between the dial and the lumed markers and the orange accents doing the heavy visual lifting. The grey variant is the more contemporary of the two, running a monochromatic register where the whole dial reads as one soft graphite tone until the orange GMT tip enters the frame. If your rotation already has a black flieger, the grey is genuinely the more interesting pickup here.
The 24-hour hand and the internal bezel between them cover the GMT complication end to end. Legibility in low light is properly strong thanks to the C3 lume coverage across markers, hands, and orange GMT tip, which is exactly the kind of low-light reading a pilot GMT should offer without needing to compromise on the dial architecture.
The Internal GMT Bezel and Second Time Zone
The Frankfurt GMT's defining feature has always been its internally mounted bidirectional bezel, and the 40 millimetre version keeps it fully intact. The bezel is ball bearing mounted and adjusted via the second crown, which is the distinctive stacked twin crown configuration that has been signature to the line since introduction. In practice, this means you set your home time on the 24-hour hand via the main crown, then rotate the internal bezel to pin a third time zone (or track your local one) via the second crown.
For business travellers and frequent flyers this is the correct implementation. The internal bezel keeps the case silhouette clean and low profile (there is no external rotating bezel adding thickness or catching cuffs), and the ball bearing mount gives it the kind of precise click behaviour you actually want when you are adjusting a time zone in an aircraft with the seatbelt sign on. This is not a watch trying to hide under a cuff anyway, but it wears well underneath one when the meeting demands it.
The Laco 330 Under the Hood
Powering the Frankfurt 40 GMT is the Laco 330, which is Laco's designation for a Sellita SW330-2 base movement. This is the modern Swiss workhorse GMT calibre, a 25 jewel automatic with hours, minutes, seconds, an independently adjustable 24 hour GMT hand, and a date window at six o'clock.
The SW330-2 has become the go-to independent GMT movement across the accessible Swiss and German microbrand landscape for good reason. It is widely serviceable, it holds its regulation well, and the caller GMT function (where the 24 hour hand is the one you set, rather than a true traveller GMT where the hour hand jumps) suits the way the Frankfurt is designed to be used. Home time on the 24 hour hand, local time on the main hands, third time zone on the internal bezel if you need it. Fine for the way most GMT owners actually travel.
Strap Kit and the Full Aluminium Set
The Frankfurt 40 GMT ships as a proper set rather than just a boxed watch. Out of the aluminium case (finished in silver with the Laco branding) you get the watch itself fitted to a black water repellent Fibertech strap, plus an additional two-piece nylon strap in orange and grey, a strap changing tool, and a “Remove Before Flight” keychain for the aviation nerd points (I must say at this price and quality, this is unheard of).
The two strap system is exactly the right call for a watch at this price point. The Fibertech is a genuinely capable everyday strap (water repellent, comfortable on the wrist quickly, and finished with a dark sandblasted stainless steel buckle that matches the case), and the nylon in the orange and grey colour combination pulls out the accent hues from the dial in a way that makes the watch feel like a different piece entirely. Swapping between the two is a thirty second job with the included tool, which is exactly how a modern pilot GMT should be.
I mean, look at this wonderful presentation.
Why It’s Special
A few things in particular set the Frankfurt 40 GMT apart in what is otherwise a very crowded accessible Swiss and German pilot GMT segment.
- A proper downsize that keeps the brief intact: Most 40mm reinterpretations of an existing 43mm piece end up compromising on either the dial architecture or the water resistance. The Frankfurt 40 GMT holds the 20 ATM rating, the magnetic protection, the internal bezel, and the twin crown layout, which is a properly disciplined engineering result.
- A Red Dot winning design in a more universally wearable size: The original Frankfurt GMT earned its Red Dot Award on the strength of the design brief. The 40 millimetre version brings that same brief to wrists between 6 and 7.5 inches without diluting the visual language.
- The full pilot kit approach: The included aluminium case, second strap, changing tool, and "Remove Before Flight" keychain make this a genuinely complete package. Most accessible pilot GMTs in this bracket ship the watch on one strap and expect you to figure out the rest.
- 100 years of Pforzheim flieger provenance for under two thousand euros: Not many centenary German watch houses are still shipping pilot GMTs at this price point. That combination of history, magnetic protection, 20 ATM water resistance, and a Sellita SW330-2 platform is genuinely difficult to match at $2,220 / €1,850.
A Pforzheim Pilot GMT That Finally Fits Modern Wrists
The Frankfurt 40 GMT is the version of this watch that most collectors will actually want. It keeps everything that made the 43 millimetre original an award winner, adds nothing that dilutes the design language, and simply lands the case size where the modern pilot GMT market has been quietly moving for years. The dial choice between the black and the grey gives you a genuine editorial fork in the road, and both are considered enough that neither feels like a lazy variant.
At $2,220 / €1,850, this is one of those releases that sits comfortably at the top of the accessible pilot GMT segment. You are getting a full aluminium set, two straps, magnetic field protection, 200 metres of water resistance, a Swiss Sellita SW330-2 GMT movement, and 100 years of Pforzheim watchmaking provenance behind the piece. The spec-to-price ratio is properly convincing.
If you have been waiting for the Frankfurt GMT to come down to a size your wrist can actually live with, this is the one. And if you have not, the grey dial is quietly the most interesting German pilot GMT release of the year.

About Laco Frankfurt 40 GMT: Key Questions Answered
What is the difference between the Frankfurt 40 GMT black (Schwarz, ref. 862187) and grey (Grau, ref. 862188)?
The two references share the same case, movement, crystal, straps, water resistance, and GMT complication. The only difference is the dial colour. The Schwarz runs a classic matte black flieger dial that leans hardest into the traditional pilot watch language, while the Grau uses a matte grey dial that reads as almost monochromatic with more contemporary character. Both share the thermally blued hands, the orange GMT accents, and the airplane on the seconds hand.
How does the Frankfurt 40 GMT differ from the original 43mm Frankfurt GMT?
The 40 millimetre version keeps every functional element of the 43 millimetre original, including the 20 ATM water resistance, magnetic field protection, internal bidirectional bezel, twin crown layout, and the Sellita SW330-2 based Laco 330 movement. The change is purely dimensional, bringing the case diameter down from 43 millimetres to 40 millimetres, which suits a wider range of wrist sizes. The lug width is 20 millimetres and the watch weighs approximately 82 grams.
How does the Sellita SW330-2 (Laco 330) GMT function work in practice?
The SW330-2 is a caller GMT, which means the 24 hour hand is independently adjustable via the crown while the main hour hand tracks with the minutes. In practice, you set your home time on the 24 hour hand, keep local time on the main hour and minute hands, and use the internal bidirectional bezel (adjusted via the second crown) to track a third time zone if needed. This is the correct implementation for travellers who want to keep home time visible at a glance rather than a traveller GMT where the hour hand jumps between zones.
