I am a collector of Ottoman pocket watches. I recently purchased a K.Serkisoff & Co Pocket watch. It has a Billodes mechanism inside. I have been trying to date or approx. date of this watch was made. Although I have been searching for a web site for the serial numbers of this kind of pocket watches. I could not find a trace. All I know the Company Zenith had started watch business as Billodes.
If anybody who is familliar with Serkisoff watches could help me I would be very Happy:thanks.
The silver case and the dust cover of the pocket watch has the following numbers. 2074296 - 1480
