Bremont ALT1-ZT/51 GMT Chronograph Watch

Bremont ALT1-ZT/51 GMT Chronograph Watch Watch Releases

What do you get when you cross Bremont‘s relatively new ALT1-ZT with the warm vintage tones of their highly-desirable P-51 LE? The new Bremont ALT1-ZT/51 GMT Chronograph. The ALT1-ZT was announced at Baselworld 2015 and served as a rethinking of Bremont’s original military GMT chronograph, the ALT1-Z of 2007. Preserving the clutter-free and highly legible design of the ALT1-ZT, the new ZT/51 completes the circle by looking back at a long sold-out model and picking up some of its recognizable styling.

Explaining the concept behind the Bremont ALT1-ZT/51 GMT Chronograph, Nick English (Bremont’s Co-Founder) says: “For me, the ALT1-ZT is arguably the most handsome and practical GMT chronograph we have manufactured to date. It is beautifully simple, easy to read and a watch you would happily see strapped to your wrist in 20 years’ time. One of our most iconic limited editions to date is the sought-after Bremont P-51. The heritage look and feel of this timepiece inspired many collectors internationally and it seemed fitting to pay tribute to it through the new ALT1-ZT/51”.

The dial layout and markings remain unchanged from the ALT1-ZT, but the new Bremont ALT1-ZT/51’s chronograph sub dials (at 12 and 6) are rendered in a metal finish, and the running seconds display has been muted through the use of markings that are nearly the same color as the dial, though the punchy red seconds hand remains.

With a warm matte brown-black dial and custom-colored Super Luminova markers, the Bremont ALT1-ZT/51 GMT Chronograph offers an entirely different charm when compared with the clean, almost gauge-like aesthetic of the ZT. While I’m not generally a fan of faux-aged lume, I think it looks just as good here as it did on the P-51 back in 2011. The contrast between the dial, the metal subdials, and the markers is really effective, and the Bremont ALT1-ZT/51 GMT Chronograph looks fantastic on a brown leather strap.

Specs remain unchanged from its sibling, with the Bremont ALT1-ZT/51 GMT Chronograph using a 43mm hardened steel Trip-Tick case, a wonderfully anti-reflective domed sapphire crystal, Roto-Click internal rotating bezel, and 100m of water resistance. Its bevy of functions, including time, independent 24-hour GMT “Zulu Time” hand, and 12-hour chronograph, are supported by Bremont’s BE-54AE automatic COSC movement. The BE-54AE is a Bremont-modified ETA 7750 and offers 42 hours of power reserve, a 4Hz rate, and can be seen via the Bremont ALT1-ZT/51 GMT Chronograph’s display case back.


I now have an ALT1-ZT in for review (stay tuned), and it’s an excellent watch and a good example of Bremont’s strengths: toughness, legibility, and multi-role capability. The P-51 was limited to 251 units and, as one of the earlier Bremont aviation LEs, they have appreciated in value and are rarely seen changing hands. Most of Bremont’s core production lineup is built around relatively modern designs, so the Bremont ALT1-ZT/51 GMT Chronograph offers a look and feel often reserved for their limited edition pieces like the P-51, the Norton, and the Codebreaker.

If the ALT1-ZT was too stark for your tastes but you want something different from their recognizable core line up, the $5,895 USD Bremont ALT1-ZT/51 GMT Chronograph looks like an excellent mix of modern form factor with just a touch of Bremont’s proven ability to elicit the warm aesthetic of WWII aircraft.

    A good example of where in-house snobbery is not completely without merit. The movement is clearly not built for this watch as it is much too small for the case. Could have been sorted with solid case back though. Now it’s a constant reminder that the watch is the product of alien parts cobbled together (albeit nice parts and nicely cobbled)

    • The ETA 7750 family of movements are 30.00 mm in diameter and 7.90 mm thick. They are on the larger side of industrial/commodity movements. Just how big did you want it to be? The exhibition back does not fully show the diameter of the movement. The 775x is an integrated chronograph and in some versions support a GMT hand, so I’m not sure which “alien parts” are bothering you.

      I think this is a great looking 775x based watch. Pricing about what I’m come to expect from Bremont.

      • Mikkel Bau Jungersen

        It’s not that the movement is too small (although a larger movement diameter would enable a bigger mainspring and rotor) and I have nothing but respect for the 7750. It’s that case and movement are so different in diameter.

        It’s like popping the hood of your brand new Audi only to find that the engine is from Volkswagen and only takes up half the engine bay.

        • iamcalledryan

          But it IS from Volkswagen (Group)…

          I must say I do agree that a little movement and little exhibition back on a larger watch, looks off. I would have been fine with them using a solid back. But a large in-house chrono GMT and this would be a $15k watch.

        • Sevenmack

          For most of the history of watchmaking, companies used off-the-shelf movements from other producers. Makes sense, especially from the perspective of maintenance and efficiency. So I’m fine with the use of an outsourced movement.

          As for cars using engines from other makers: Rolls Royce uses BMW engines. Yet you would never call those cars the finest in the world. If it is fine for Rolls Royce, than it is also fine for every watchmaker.

  • Ulysses31

    A handsome pair of watches that escaped the usual design missteps I have come to expect from Bremont. The small movement does look silly – thankfully it won’t be visible when in use. I don’t like the rotor, which looks like a bunch of spoons were cut out of it.

  • Dave Tucker

    Wow, for me this is a beautiful watch. I love the super clear dial and retro design. I want one!

  • PleaseSpellRoman4AsIV

    I generally like what Bremont does and the metal finish of the sub-dials is great. Not too sure about the vintage lume, and the fact that they did not change it on the date wheel too to at least keep it consistent. I guess I will stick with yearning after the MKI.

  • WImads

    Make it in Titanium and 40mm, and I’ll scrape together some cash!

    • Coert Welman

      I am so with you on that one! Excellent suggestion.

  • word-merchant

    I really like this… normally I’m one of the first to go off on one about small movements in big cases (posts passim) but somehow it all just works here – the date window sits perfectly next to the hour lume marker as does the small seconds at 9 o’clock.

  • DanW94

    Nice looking watch, the muted dark colors give it a masculine appearance and the dial is well balanced. I really like it. It has a subtle confidence to it.

  • Marius

    This Bremont ETX 231 whatever, is a wonderfully wonderful watch. Everything is just superb until you see that it uses a 7750 movement. I’m sorry, but asking almost $6,000 for a 7750-based watch is simply unacceptable, given that Chr. Ward charges $2,000 for a watch using almost the same caliber.

    For $5,900 you can get an IWC Pilots Chronograph, which is better looking than the Bremont, and also has a real heritage and history.

    • iamcalledryan

      Not sure what basis your disdain for the 7750 is, but it’s a perfectly good tool-watch movement. In any case this isn’t a 7750, it’s a 7754 – notice the additional central hand with the red triangle tip? That’s an extra complication, and for sub $6k it’s a pretty decent GMT Chrono Date. Then there is the case construction, including the unusual band and the internal rotating bezel that, again the IWC lacks.

      • Beefalope

        There’s absolutely nothing wrong with a 7750 — or, in this case a 7754 — but Marius does have a valid point. We’re talking about a $6k watch compared to a $2k watch that more or less uses the same movement. I’ve seen plenty of examples of cases from Bremont and C Ward. Although Bremont cases are better, there is no way in the world they are $4k better. Also, Bremont dial finishing leaves much to be desired at their price point.

        And, yes, by the way, I think IWC is guilty of the same thing.

        Hell, the Seiko SDGZ013 has a technically advanced in-house movement and is superbly finished at a price around $2k. It’s a better watch at its price point than anything the Swiss produce at a comparable price point.

        We may debate the technical merits of movements and cases all we want, but the reality is that a great deal of watch pricing has to do with branding.

        • iamcalledryan

          I totally agree with your last point.

          I think the issue is trying to reverse engineer the retail price by counting the assumed cost of production. I have never assumed that a watch would only be the sum of its parts and that is why of course the price difference between C Ward and Bremont isn’t solely explained by quality/cost.

          it is clear that for you and Marius, for the knowledge that you have of watches and your respective budget, you don’t see this as reasonable. But $6k for this watch is going to be a perfectly decent proposition for the people that do buy it. If I were in the market for such a thing I would seriously consider it. It is not important that every watch in my collection be in-house, and while I am sure there is a roof to anything housing 7754, $6k is not it when the watch is nice enough.

          Take a look at the market for other GMT Chronos out there – this is hardly a rip-off. The Omega Seamaster Aqua Terra GMT Chronograph has a cooler movement but costs 50% more. Master Compressor is even cooler and even more. The Mille Miglia uses the same movement and comes in at $6k. The Sinn 756 DIAPAL uses the same movement and you can pick it up for around $4k but the styling is less sophisticated.

          Bottom line there is not a large pile of better GMT chronos out there for less.

          • Beefalope

            Not to address your points directly — and they are valid, by the way — but I would like to offer a suggestion if you want a unique 7750-equipped chronograph with a magnificent design, terrific case, great finishing and overall superior build quality: Jorg Schauer.

            They’re hard to find and don’t have GMT hands, but they’re the best 7750-equipped chronos I’ve seen under $5k, and possibly under $7,500.

            I was thinking about buying a Bremont used — when the value proposition becomes much more palatable to me — until I stumbled upon Jorg Schauer, and I found that the JS was easier on the wallet and just better for my tastes in every way.

          I havent seen bremont in the flesh, but I must agree on IWC. I was quite disappointed when I saw those in real life for the first time. Nothing like the price tag would suggest… and it is not that it isn’t possible for the money either, they were displayed next to some baume & mercier watches, which left me unimpressed online, but wowed me in the metal; both the case and dial finish, simply stunning. And they are substantially cheaper than IWC too…
          It is certainly a big portion of marketing, such a shame. I’d rather have them spend their marketing budget on the finishing.

        • Chaz

          I ordered the Moto Keure or whatever it’s called with Seiko movement, wood accents and a lovely deep brown dial.

          Seven hundred bucks.

          Can’t wait to receive it.

  • Spaceguitar

    I really like this one; I’m not even sure which I’d pick. One of the cooler winding rotors I’ve seen out there too. Good analogy Mr Stacey…I concur with the “warm aesthetic” they’ve captured. This might be the first Bremont that’s really spoken to me.

    But unfortunately my checkbook then spoke to me and said “Don’t get any cute ideas dumbass!”

  • Jerry Davis

    I love this. Classic and clean.

  • iamcalledryan

    Handsome, tooly, and just enough personality to elevate it above the generic, but perfectly efficient guts. I like where this is going, even more when I learn that Stephen McDonnel (of MB&F LM Perpetual fame) is helping Bremont with production.

  • Michael Kinney

    Bremont must be a brand one has to see in the metal. Or I do, at least. Photos, even of a handsome COSC, GMT chronograph such as that one, leave me with a big “meh?”
    However, when I first saw a Supermarine i was absolutely mesmerized, and i don’t even like the handset on that one!
    I suspect it’d be the same with the ALT1-ZT/51 GMT.

  • Beefalope

    Good design, bad price. Same old Bremont story.

  • Matt Smith-Johnson

    I really like it. I have nothing bad to say about it. 😉

  • otaking241

    Can’t get excited about this brand at all. Ho-hum design, bin-sourced parts, non-existent heritage, priced way above watches that check all those boxes and more. Who’s buying these?

  • Boogur T. Wang

    I look forward to your comments.

  • Chaz

    I’ll take the Alpina featured next to these

  • I_G

    Good design subduing the subdial at ‘9’ to decrease the 7750-ness, but still it’s just another 7750 chrono – branded after a French peasant.

  • funNactive

    Nice design. I like the internal rotating bezel – although, for me, a dive timer would be more useful than a GMT.


    good looking watches, nice looking case, decently decorated work horse movement.
    if it can be had at 50% off then maybe a decent deal. Anything above is just too much.
