    Help identifying a seemingly rare 1920 Longines pocket watch

    I received an open face pocket watch from my father for graduation from engineering school almost a decade ago, which I have only recently begun to use on a daily basis. The watch was originally given to my grandfather as a gift for graduating from engineering school himself on Dec. 25, 1923. I can't seem to find a photo of another watch that looks the same on any site. Can you help me identify it (model)? The serial number next to the mechanism is 3835218. I would also like to know if I can have the discoloring to the face restored.

    Any help on this?

    A 1922 Longines
    As Longines have ALL their hand written records, you can write to them with details and they will tell you when and to whom the watch was sold.

    Personally I would leave dial as it is

    Unfortunately, Longines wasn't able to tell me much, except that it was originally to be a wristwatch sold under Longines Wittnauer. They said the caliber was 18.79ZZ, but what does "caliber" mean? This is obviously a pocket watch, did they use the same insides for wristwatches, just relocating the winding mechanism, or perhaps adjusting the face by 90 degrees? Is there any information out there on this Wittnauer company?

    Seems they told you a lot
    Can you post EXACTLY what Longines said?
    Caliber is the movement type.

    "Following your request, we have the pleasure to give you the information found in our old registers:
    at the origin, the serial number 3’835’218 identifies a Longines manually wound mechanical movement, caliber 18.79ZZ.
    It has been invoiced to Longines-Wittnauer, Longines’ branch in the U.S.A., on 08.07.1922.
    It was aimed to be fitted in a wristwatch, which case and bracelet were produced in the USA under Longines license."

    Thanks
    All makes sense
    It was sold ONLY as a movement and by that date expected to be fitted in a wristwatch - that said I doubt Lepine/Open faced movements were going into wristwatches)
    so it ended up, as it was originally designed as a pocket watch - Open Face (Lepine)'
    and sold by Longines agent Wittnauer

    all is good

    An update from Longines:

    "I am sorry to say your movement was aimed to be fitted in a pocket watch, which case was produced in the USA.The caliber number 18.79ZZ is the name gave to the movement. The number 18 indicate a unit of measure still used today to describe the size of a 18.79 lines movement. A line is 2,255 mm."
