I can really use some help from you to identify an old pocket watch that I have for many years now. It doesn't say any brand or writing on the watches face or on any of its back panels about the producer. It only says Cylinder 10 rubys. Until now the one thing that I was able to find out about it is that it has the silver markings 0.800 on its first back panel.
I was wondering if anyone of you cold enlighten me regarding the period that this watch was produced, and the actual manufacturer.
I have attached some pictures with the watch below.
Thanks in advance, Alex.
