    Foreword

    I’m sorry for the long title. Exactly with this slogan AirNautic introduced this watch we have here today - "the world’s most robust 24 hour Swiss made pilot’s watch". This limited edition of 50 pieces watch hand made in Switzerland is really something special and when one of them appeared in our WUS sales forum I could not resist. The price (incl. shipping) was about $600 (box – no, papers – yes).

    Comments

    Three years ago in 2009 we had in this forum excellent AirNautic AN-24 review by Dennis Smith: AirNautic AN-24 Pilot...REVIEW!...... I advise to read it again, nice photos and matter of fact review. In 2010 AirNautic Watch Company released one special and very different model of AN-24 family – manual wind AN-24M. The differences are so big that I decided that AN-24M deserves a separate review.

    Some words on AN-24 pilot watch family. Here we have four main versions (there are also several subversions with different lugs etc.):

    1. AN-24 Pilot – watch reviewed by Dennis
    2. AN-24 Submarine – with fully luminous white/grey dial for low light conditions (one subversion here is Submarine Tritium with tritium tubes)
    3. AN-24 GMT – with a second time zone function
    4. AN-24M – watch reviewed here

    Watches 1-3 can look different, but different is only dial, essentially they are the same watch (same case, same movement).

    When we take the standard AN-24 Pilot and AN-24M, then at first glance they appear to be similar. But similar are only dials. These watches are very different – the dimensions, movements, cases, everything is totally different.

    Actually even the dials are different in details – AN-24M has no date window and instead of sweep second hand has small seconds at 9. These differences are obvious because the movements are different.

    The rest on AN-24 family is equipped with ETA 2893-2 automatic movement, but AN-24M has customized manual wind ETA 6497. This is famous movement used by many good watchmakers.

    Movement 6497 was created by Unitas in the 50s for pocket watches. It is very big movement – 16.5 lignes (36.6 mm). ETA owned Unitas for a number of years and continued to make these movements. The movement is produced now mainly as model ETA 6497-1. There is another modification 6497-2, which has higher beat 21,600 bph. The original 6497 is of course 12h movement. For AirNautic it is customized for 24h.

    As I said, these great looking fine movements are used by many brands and the possible decorations are countless. Here with AN-24M we have 6497 with Geneva Stripes (in French Côtes de Genève) and blue screws. Display case backs are very nice with manual wind movements. From automatic movement you can often see through display window only the dangling rotor. Decorated 6497 movements are so gorgeous that most watchmakers try to make the display as big as possible to show you all the glory, as it is case here.

    If you are interested in different 6497 decoration possibilities (plain, hammered, golden, perlage, engraved etc. etc.) then please take a look at Tourby Watches (BTW, our Watchuseek sponsor) Movements - TOURBY WATCHES HAGEN IN WESTFALEN.

    There is another sibling movement – Unitas/ETA 6498. Both are originally pocket watch movements with the same size. The difference is placement of small seconds. When the crown is at 3 (like here), the 6497 has seconds at 9, but 6498 has seconds at 6. In pocket watch terminology the 6497 is called Lépine movement (for open face case), 6498 is Savonnette movement (for hunter case).

    Here are both movements according to ETA tech manuals - 6497-1 on the left, 6498-1 on the right.



    AirNautic decided to use open face pocket watch movement, that’s why small seconds are opposite to crown at 9.

    Next week I promise to review one very nice 24h watch with 6498 movement, where small seconds are of course at 6.

    Now let’s look at the case. This is again something very special. First, as the movement is very big the case is big too – 44 mm without crown (3 mm more than the rest of the family). But what makes this steel case special is that it has been sandblasted and then Cold Carbon hardened. AirNautic said that the result is four time hardness of the standard 316 stainless steel. When introducing AN-24M AirNautic said:

    Are there any drawbacks? One (which I agree) was mentioned commenting Dennis’ review

    Im still on the fence thinking about the current design is the best of it all or not? Too many hourly markers and numerals. If i would bring the hourly circle further to the center of the dial (or even cancel the circle, just keeping the numerals), delete odd numerals and short strokes between hour. Shorter and thinner hands. This design will be a winner for me.
    Finally I have to say again, that this watch is limited edition of 50 watches only. I got number 10. Interesting, how many of them are landed here among WUS members?

    As you know my pictures are worthless. They are maybe good only for some registry. If you like to enjoy really nice pictures of AN-24M then please, here they are: AN-24M photos

    Summary

    One of the best watches I have, no doubt. The biggest problem for me would be that my wrist is very small and this watch is BIG. But I will not let myself be distracted. Today I was wearing this watch and got good comments from colleagues (btw, the main attractors were orange hands J). This happens very rarely, when somebody pays attention on wristwatch you are wearing, at least in this country where I live.

    Beautiful watch and a great, informative review. I did not know the case was hardened, neither did I know the sapphire crystal was domed on that model (I wish it was on my AN-24). Thanks!

    Does the watch have to be that big? I have a watch that uses a Unitas base caliber (the movement is highly modified) and the diameter is 42 mm. It's still on the big side. I'm not too sure that visibility is an issue anymore once you get about 40 mm in diameter, which is comfortable for most people to wear. Would have loved to have seen them keep the diameter down a bit.

    With a case that tough you could hammer nails with it and not leave a single scratch on the case. How much does this watch cost new?

    Redone 6897 and crown 'with four gaskets' is cool combination! Very interesting watch.

    Very nice for the price. I like the Submarine model in particular.

    Had to resurrect this thread...I finally broke down and ordered one of these. Should be perfect for my current needs (no need for a date display at this time, nor for a second timezone). I only hope it doesn't wear too big on my 6.5 inch wrist. Should be a great watch for me, and beautiful front and back.

    Question for owners: I know the crown has four gaskets, and it's rated to 100m. I was hoping that since it's a manual wind that it does not have a screw-down crown. Can someone confirm this?
