    The letters i/S when used in this way mean "in Saxony" so a wild guess might be that Carl Rahm was located in Berlin. You might try trade directories for the first few decades of the 20th century.

    You might check Bremen, Germany (fairly large city SW of Hamburg), as well. Several Carl Rahm's immigrated to the States from there ...

    mjames - The 2007 version of the Guide/Shugart notes that the Zenith brand was registered in 1897 and that they had made 2,000,000 by 1920. Post a photo and we can get an idea of the production date but I will guess your watch will date to 1915-1920 as production is likely to have been lower in the early years. Mike

    so can it be a safe assumtion to say that the serial numbers used by zenith were in seqential order? Lower numbers being earlier and going up?

    It is not "safe" but it is reasonable in the absence of evidence to the contrary. The numbers were most likely blocked off in groups of 100 or so of a given quality and model that started production together. Once the industry settled into relatively high volume production, that was the pattern with most companies.

    Batches were finished according to volume demand, so a low volume higher grade watch might have the batch open much long than a high volume lower grade watch.

    Once again, this is speculation for Zenith, but was the general pattern of the industry.

    That is only the seller, in Germany some watches have this, it is uninteressted. It can also be Bern, Biel, Büren etc.
    The movement is Zenith cal. 18 (i think)swiss, very nice.
