    (Post moved to Public, the more suitable forum)

    That's a no-brainer. It is a 7750 CCL.

    From a former post

    The ETA/Valjoux 7750 pedigree

    The ETA/Valjoux 7750 is a very common chronograph movement with a huge pedigree:

    Valjoux 7750 (since 1973)
    Valjoux 7751 (since 1986)
    Valjoux 7753 (since 2002)
    Valjoux 7754 (since 3003)
    Valjoux 7757 (1985-2003)
    Valjoux 7758 or Valjoux 7750 CCL - "con cours de lune" (since 1985-2003)
    Valjoux 7760 (1985-2005) the handwounded 7750 version:
    Valjoux 7761 (1986-1998)
    Valjoux 7765 (1983-1998)
    Valjoux 7768 (1985-1998)
    Valjoux 7770 (since 2002)

    And now we have to add the 7750 based "Valgranges" movements (ETA VALGRANGES) which have been developed and are made by ETA, their basics go back to the 7750/7760 Valjoux movement which is smaller than the Valgranges (diameter of 36,60 mm (ETA say 37,22mm, 16 1/2 lines´´´).
    The "Valgranges" should be interpreted as an answer to the demand of bigger watches though.

    Valgranges A07.111 three hands/date indication
    Valgranges A07.161 three hands/date/power reserve indication
    Valgranges A07.171 GMT/date
    Valgranges A07.211 chrono

    The Valjoux 7750 comes in a bright variety of modifications, for example made by
    + Alfred Rochat, Chronoswiss (C. 732 or C. 741, C 741 by Rochat)
    + Fortis (developped byPaul Gerber featuring an alarm and two springs)
    + Franck Muller (for example FM 7850 CC MB)
    + IWC
    + Jacques Etoile (cal. IV.C4)
    + La Joux-Perret (for Jaquet Droz watches for example)
    + Paul Picot ("Atelier Technikum")
    + Panerai
    + Porsche Design (Eterna 6036)
    + Revue-Thommen ("Airspeed Flyback")
    + Sinn ("Flyback")
    + Soprod.

    Here's my 7750 CCL

    Hello stuffler,mike ,

    thanks to this thread I found out after a year that my movement has a little chance to be repaired.......I have a Cortebert movement as the att. photo but I can't find the broken lever ,I asked to many watch makers and also to Cousins.co.uk but from this last no answer yet,
    do you have any idea how can i get the part number and who eventually has it?

    thank you
