    My guess is that you already (or should) know the answer and wait for an offer...

    Yes and no it is a modified Lemania 1340. Omega made it their own 1040 calibre by adding a 24-hour indicator inside the running seconds subdial and increasing the jewel count from 17 to 22.

    But that's a simple google search...

    Omega never touched these. Lemania made them100%.
    Being the flagship of the SSIH, Omega got the version with the 24h indication.
    Lemania and Omega at the time, from 1932 until 1982, was under the same ownership.
    All chronograph and other complications movements was made by Lemania within the group. Alarm, moonphase, chronographs. There are no documented exceptions I know of.
    Omega did not obtain tooling for chronograph movements until the tools for caliber 86x/186x was moved to Bienne in the mid 1980s.

    I agree with you 100% but this depends on viewpoint... The movement as used in this watch was not in another manafacturer, and spare parts from a 1340 may not work on this watch. I think we are both saying the same thing, and we get into the fuzzy area of what defines inhouse movements 40 years before it started to become a real issue.

    Agreed. The 1340 and 1040 are not completely identical, but both where made by Lemania. 1340 inhouse and for others, 1040 exclusively for Omega.
    BTW Lemania made 134x versions with fine regulation and 22 jewels for themselves and others as well.
    The 24h indicator remained an exclusive "Omega only" complication.

    I appreciate your answers. Now I am sure that movement is 100% Lemania.

    One of the important differences between the 1340 series and the 1040 is that the 1340 is unidirectional winding whereas the 1040 is bidirectional.
    Almost all if not all other parts are interchangeable .

    I do believe 1040 and 1340 are both sharing the auto winder construction. Both bi-directional winding.
    Calling @Andy K in on this one as he is the inhouse Guru, capital G, on these lovely pieces of horological artwork.

    I may be wrong but
    Avatar is wrecked 1345 I rebuilt.
    I purchased an Omega 1040 bidirectional winding gear (see bronze gear in photo) only to find it does not work in a 1340. The spring is the old rachet stop spring that restricts the winding gear spinning back on the unidirectional 1340
    The Omega packet contain the other gear needed for bidirectional .

    I have little experience with the 1340 or 1341, but I am certain the Omega 1040 is bi-directional. I will have to turn in my capital G! :) Good info @mollydooker ! :thumbsup:

    Thanks. Initially I resorted to the 1040 parts list as the Lemania is in French hence buying the wrong part.
    If you need a 1040 winding gear it's yours.

    The 1345 is definitely part of the family but have its specialties.
    I am out from home the next few weeks so no access to whatever little reference literature I got.
    Here's a couple of pictures I found showing the otherwise sealed reversing wheel (from an Omega 1040).
    Those parts are really tiny....,,

    It may well be that only the 1345 is unidirectional and once again my assuming made an ass/u/me.

    I am interested in establishing this. The 1340 and 1341 versions of the movements are incorrectly identified by Ranfft.
    Could it be that the 22-jewel versions is bi-directional winding, and the "budget" 17-jewel versions are uni-directional?
    The 1345 is 17-jewels BTW.
    Just a thesis, but it would be interesting to have it checked.

    This section in the 1340/1341 fornitures catalog from Lemania states that there are different parts between the 1340 and 1341 calibers. Auto winder parts are included in that overview:

    Interesting , the above 1341 shows unidirectional part 1428 which is the rachet stop spring which is screwed on under 8500 Chronograph bridge and sits against the winding gear that meshes with the differential preventing it reversing.
    I managed to source the correct winding gear from a lovely Italian gentleman who told me the 1040 would not work but as his English was limited I did not understand what he was telling me until it was too late.
    Since restoration I wear it regularly and never had an issue and normal wear builds reserve quickly. EXCEPT , when I wind it (5 winds if from rest only) the rotor spins as well . Again the Italian gent told me to use plenty of lube on the winding gear but I did not understand what he was saying at the time.
