    Hi guys

    I have this 3/4 size Zenith, trying to figure which year the watch is produced. Can anyone help?
    I understand that the number on the movement does not correspond with the serial numbers for Zenith.

    Kind regards Dag

    Rossler says the 122 was a Martel movt first supplied in 1930. The article I quoted above has a member saying they came from UG

    Based on the movement serial I assume that the serial would have between 800 and 900k if it was a Berthoud/Jaeger (i.e. not a UG). Reference 22209 is a close sibling. An example with closish serial (170k-175k): https://watchcharts.com/listing/359...l-geneve-compax-ref-22209-vintage-chronograph

    So the number in the case back does not fit in the Zenith serials but it looks like a UG serial with 1 digit added. There are more examples of this see for instance in this thread at WUS: https://www.watchuseek.com/threads/a-little-help-with-a-cal-136.3774442/
