Longines Lindbergh 47MM Automatic ‘Hour Angle’ Watch Review

Longines Lindbergh 47MM Automatic 'Hour Angle' Watch Review Wrist Time Reviews

Case architecture is interesting, full of nice details. One of the best is the brushed lower bezel that has indicator cuts on it. This is to help with the Hour Angle system while the watch is off. You’ll never use this feature, but it is a cool visual detail for sure. Water-resistant to 30m, the case differs from the original also in that the rotation of the inner disc is controlled by the crown (when pulled out to the first position) as opposed to having a secondary crown. I don’t mind this at all, the system works pretty well. The large, onion-style crown is comfortable to grip, and attractive looking.

The freely bidirectional rotating bezel has a small metal notch at the “12 o’clock” position, whose purpose I don’t fully understand. My only thought is that it helps you orient where the “top” of the bezel is in situations where visibility is limited. Unless you are actually using the watch to calculate your navigational position, the rotating bezel doesn’t seem to have much of a secondary use. Alternatively, the inner rotating disc is something that has more practical use. Also freely moving, it has a 60 minute track as well a 15 segment track. I don’t understand all of its historic purpose, but it was apparently used to synchronized the seconds hand with radio signals. Today this feature can be used similarly to a rotating diver’s bezel to measure an independent 60 minute segment of time.

Longines apparently recognizes that this disc has modern appeal, and uses it in the Weems collection watches, which as I said used the same case and movement as the Lindbergh, but without all the Hour Angle stuff. So what of the Hour Angle system and how does it work? I’m not an expert and despite doing some research I haven’t found anything which easily explains it – though the idea is simple enough. In essence the system relies on the fact that if you know the position of the sun at noon, you can interpret where you are longitudinally on the globe given the fact that the sun appears to move around the earth (from our perspective that is) one full time each 24 hours. That movement arc is separated into 15 segments, which can be further subdivided to help give you an even more precise location.

When using the Hour Angle system you need to make sure it is noon, and then you need to line up the watch with the sun, look at the position of the hour hand, and then perform a mathematical calculation. When done correctly you could relatively precisely know at least one dimension of where you are located on the earth. If you do not know exactly when it is noon, or if you cannot see the sun, then you cannot perform the calculation. The concept was adapted from one of the ways a sextant device works, by Mr. Lindbergh as I understand it.

Whether or not you understand how to use the Hour Angle system isn’t really important to appreciating the watch. I don’t think I’ll ever do the calculation, nor do I think anyone who is an actual pilot outside of doing it to establish some inner level of nerd credibility. I put all of this in the same category as rotating slide rule bezels on watches; i.e. they look cool but no one will ever use them.

The Longines Lindbergh dial is full of markers and indicators related to angles, degrees, etc… If you like how it looks, then I think the watch will satisfy you. If you prefer a more simple look, Longines produces essentially the same watch, sans the rotating bezel, with a cleaner dial that has Arabic or Roman hour numerals. With that said, I still think the Lindbergh version is the most desirable because the proportions work the best (for example, the relative length of the hour and minute hands to the hour markers).

The white dial of the standard version is lacquer, and done pretty nicely. I really like the blued steel hands that look like flame blued ones. I am not sure if they are actually flame-blued or color treated, but Longines seemed to make sure these pomme-style hands look as good as possible in their blue color. The biggest problem with the 90th anniversary limited edition is that the hands are polished steel, and make for sub-optimal legibility. Longines wanted to make a more contemporary version of the Lindbergh with the 90th anniversary model, and it does have a good look to it. Though it really needed different hands in my opinion. The shiny, polished hands, mixed with the glossy surface of the brushed silvery dial simply makes for a less than ideal readability scenario. More so, certain visual elements (such as some of the markers on the inner rotating disc) on the 90th anniversary model are difficult to read for similar contrast-related issues.

Longines uses a steel rotating bezel for both versions, with the bezel on the 90th anniversary model being in PVD-coated black. Also, the 90th anniversary model case is mostly titanium, while the stock model is in steel. There are some weight savings for the titanium, but as I hold each of the two watches in my hands, they more or less feel the same. In all, if I was to choose between the two models, I would go with the “truer to original” white-dialed version given its looks, legibility, opening caseback, and excellent details. The lack of the open caseback of any kind on the limited edition really takes away from a full appreciation of the watch because the movement is such a highlight of the design.

Longines offers a real alligator strap for the Lindbergh, which thankfully tapers a bit. The 90th anniversary model comes on a really nice bomber jacket-style brown leather strap, along with a small strap extension if you are going to wear it over an aviator suit (which you are not going to do). I did find that on my sub-7 inch circumference wrists, the alligator strap was too long. I am not sure if Longines offers a shorter version of the strap. Oh, and in case you are wondering, the “EF Co” written on the back of the watch doesn’t have anything to do with flight or Lindbergh, but is a historic marker on Longines watches dedicated to the brand founder Ernest Francillon.

Even though the Longines Lindbergh isn’t a newly released neo-vintage model, it is one that many people easily overlook. What sells it for me is that the core aesthetic of the watch remains relevant today. The easy to read dial is effective and pleasant on the eyes. The multitude of colors and indicators on the dial evoke a sense of intrigue, asking yourself “what was the world like when people needed to use this to know where they were?” Features in the watch such as the movement decoration, opening caseback, and overall good quality and construction make this a real collector’s-style watch, or even suitable for daily wear. The Charles Lindbergh connection and story really help seal the deal, offering that emotional connection necessary for us to spend a few thousand dollars on pretty much any item.

Placed within the larger Heritage collection, I encourage you not to overlook the Longines Lindbergh 47MM Automatic if you are in the market for a vintage-style pilot watch. For the money you get a decent value, and it further encompasses a lot of the values you should be looking for in a Longines timepiece. Price for the reference L26784110 Longines Lindbergh 47MM Automatic “Hour Angle” watch is $5,000 USD, with the price of the limited edition reference L26781710 being about the same. longines.com

    Before your flight, you (as Lindberg, minus the racism) set the watch to GMT. Then during your flight, when the sun at high noon locally, you glance at your watch. The hour hand will be pointing to the number of degrees west of Greenwich you are. To get the exact degrees, read the minute hand on the outer bezel (1-15). And if you want to get more precise than whole degrees (87 km at the equator), then read the subdivisions in (15,30,45) on the outer bezel for the minutes of arc.

    As an example, if you are 30 degrees west longitude, then when it is high noon, your GMT watch shall be reading 2 pm.

    • Larry Holmack

      Thanks for the info!!!

      • BenC

        My pleasure. Latitude can of course be measured directly with a sextant.

        So I speculate the rotating bezel is in case you spent (say) 10 minutes with your sextant. You would then rotate the bezel clockwise 1/6 of a turn before you read off the minute hand.

    • Thanks for sharing!

    • Hayo Harmens

      If I may add to your post, the longitude which may be derived from the time on the watch in the photos above is calculated as follows:

      The hour hand is above 15, so use 15
      The minute hand is above 12:30, so use 12:30
      In red, under the second hand read 1.2
      Now add them all together and you arrive at 27°31.2’ west of Greenwich.

      The rotating inner bezel is used to correct for the imperfect synchronisation of the watch with the GMT time reference. You place the 15 where the second hand was when the minute struck.

      The big problem with using this method of position plotting is how do you accurately establish when the sun is exactly at its highest pound from a small moving aircraft?

      • BenC

        Thanks for pointing out the use of the seconds hand and the inner disc. That radio timing signal makes a lot of sense with mechanical chronometers having errors of multiple seconds a day.

        There is definitely a limit to the celestial navigation that a solo pilot can do. With only the watch, once a day by the sun is the upper limit. Weems popularized almanacs of the other celestial bodies so you could get a position fix more frequently.

        • Hayo Harmens

          Yes, in the hands of a professional navigator with all his other navigator’s paraphernalia to hand, the hour angle will have been a very useful piece of kit. But to a pilot it simply tells the time and offers a great conversation piece. I like it. I want one.

  • Definitely not my style, as I am neither a pilot or a pretend Bremont-esque airman, but I can see how this would excite some people. It’s definitely a unique design – a far cry from the usual Flieger styled pilots watches – and seems to be executed well. I just don’t understand the need for the 47mm size. People are not actually navigating aircraft with this strapped to the outside of their flight suit, so it seems like overkill. Ariel’s right in positing that a 44mm version would probably sell better; it looks absolutely ridiculous when someone wears a watch whose lugs hang precariously over their wrists.

  • Why so small?

  • Omegaboy

    The engine nacelle and propeller cone on Lindberg’s plane were covered with perlage, which is probably why Longines finished the movement like they did.

  • SuperStrapper

    I think the article indirectly does a pretty good job of summing up why this watch does not and will not have the same appeal as a speedmaster, regardless of marketing. The article/author cant describe the complication of the watch, and while maybe not everyone fully understands a chronograph they are certainly much easier to appreciate: me push button watch time me. Me push other buttons watch no time me. Aside from understanding functionality, the speedmaster simply wears nicer than. Even the modern 9xxx ones would seem trim compared to this: 47mm wide and then a 22mm crown.

    The watch looks nice and well done, but you would just never be able to position this in such a way that people give it the same status as a speedmaster.

  • PollyO

    As someone who requires a large watch, I’m always on the lookout for a larger time piece that I find interesting, attractive, high quality and reasonably affordable.

    This is not that watch. Might be to some. I hope whoever that is enjoys it. I just don’t reslly get this thing.

  • Larry Holmack

    I wouldn’t mind this one in my collection just for the coolness factor. And thanks to Ben C. for describing how to use the watch!

  • egznyc

    This is no Speedmaster. It doesn’t have much utility for all but a few people who actually fly AND have yet to enter the 21st century. The watch is kind of interesting, I think, and while the movement looks reasonably decorated, it also looks really boring and worse still, not well thought out. For its size, it could have much more power reserve – just one example.

  • Raymond Wilkie

    Busy busy busy.

  • Sheez Gagoo

    Really nice, but 47mm? And it`s quite sad, that the couvercle on the back contains more text than a Rolex so you can`t use it for personal engravement.

  • Gokart Mozart

    Why is everybody complaining about the size. It is a reissue and it is the same size as the original.

    It’s better than the usual reissues when they redo the watch and increase the size from a 36mm to 40 something so that it could be contemporary.

    Look at the wrists of loads of people who wear watches that hang of the wrist, or the 50mm Lumos of G -shock you see on people’s wrists.

  • Gokart Mozart

    Until half way down the second page I did not know which watch was which.

    As the watch talkedvabout was for the 90th anniversary I assumed the watch with the lacquer dial was the anniversary one, when in fact it was the normal one. Confusing. I could have bought the wrong watch!

    Picture descriptions in situations like this would be useful.

    • Horum Positivium

      Agreed – it is confusing. Luckily I dislike them both, so no damage done.

    • Alexander Hilsbos

      Similar here. Got confused. I miss Marius. He would have helped on this one.

  • BrJean

    Busy and puzzling in a good way, just like Breitling Navitimer.

  • I’m awaiting a Chronicles of Narnia version with baited breath.
