    I found a movement with a strange signature. Does anybody know what it might mean?

    Could the piece with the stamped (engraved) information be a service replacement provided by Omega? Would a serial number of 2,406,568 make any sense for a watch of this age?

    You know @Modest_Proposal that I have very little experience or expertise with vintage timepieces and zero experience with pocket watches. I'm just trying to do some detective work :)

    Hi,

    Nice and interesting watch!

    19LB is the caliber, as well as 19T1 and 19 LOci (or 19LOciT1). This last symbol, pretty rare - first time I see it on a watch!-, means Lepine Omega Chemins de fer italien (Lepine Omega Italian Railroad).
    These are names for versions of the 19'' but it is unusual to see them together.

    Brev means patent (Brevet in French). 8760 is the patent number of the keyless system Omega used in the 19'' cal in 1894. It is usually on the dial side of the 19'' series watches.

    I have to check for the other numbers. Could be patent numbers as well but I do not remember having seen these ones. For the moment I think it is more likely the serial number.

    EDIT: I think the last symbols are the serial number, so 2,406,568 as Jones in LA supposed, which perfectyl makes sense for this watch.

    Internal testing engraving? They made some movements with slightly different features or had different tests done in them and that's to keep them straight?

    Out of curiosity, is the 8760 patent number random/coincidental or is there some poetic allusion here? (i.e. 8760 happens to be the number of hours in a non-leap year)

    It would be a nice touch! But as it is an official registration, I am not sure the Brandts could chose the number. It is the number of the patent registered august, 1, 1894, at Bienne by Louis Brandt et frères.
