    Picture Universal Geneve - Aero Compax

    Hello and Happy new year to everyone!


    I am looking for informations about this watch, and i would be very happy if you can help me with anything. The info is not great on the net and i didn't find this kind of black dial elsewhere.


    I bought it a year ago, and it was like this:








    Then i send it for service, and it looks like this:








    The movement was cleaned, a new crystal installed, the case was polished, a second hand for chronograph was manufactured and another crown was installed (still looking for an original one). New strap UG on the way, looking for a 14mm buckle.


    Here are two vids:

    Happy New Year to you too! That's a wonderful watch - although the starting condition was already fairly good for a watch of that age. Here's some info on the movement:

    bidfun-db Archiv: Uhrwerke: Universal 287 Aero Compax

    As far as I know, Universal patented the first chronograph with additional 12-hour indication in 1937. Since the watch lacks shock proofing, I would estimate it's production as falling between 1937 and ca. 1950.

    Fonrea, there should be two numbers on the outside of the caseback. The longer of the two is the serial number, which can give you a date of production, and the shorter is the reference number. If you find them, I will see if I can find any addition info in my UG book.

    Your videos appear not to be viewable by the general public.

    I think the videos work now. :)
    Sorry for that!

    On the case back it is written: 826xxx and then 22414

    Thank you!

    Date of production is 1941. This reference is pictured in the Pietro Sala book with slightly different hands and a dial with numbers instead of hashmarks at the hours. As there were minor variations even within a reference and UG used sword hands quite widely, I think your watch is quite correct. Congratulations!

    I ordered today a Pietro Sala book myself and i think i will get a NOS crown and maybe pushers, so i hope in a month or two i will have it complete even with a strap and buckle.

    Hi,
    I found a beautiful Universal Geneve Aero-Compax, but it's movement is Universal 285? It is signed, but I cant find another Aero-Compax with 285 movement and I don't have a Pietro Sala book. Can one of you see if an Aero-Compax was ever made with a 285 movement? It looks very similar to this watch:

    If you can find one with 285, what would it be worth in your estimation?
    Thanks!!!

    Only the chap who cobbled a movement from the 40s and a case from the 60s together. A real time machine.

    The main difference between the Cal. 285 and 287 is size: the 285 is 14''' (about 32mm) whereas the 287 is 15''' (about 34mm) across. The "Aero Compax" watches are noted for having a second time zone at 12:00 so if someone advertises a watch without that as an "Aero Compax", it is probably just a "Compax" model. Judging by your link, it seems as if the Cal. 285 also came in an "Aero Compax" version.....

    As for value, we don't give valuations on this forum - the guidelines will tell you why.
