Thank you for your help, Mr. H.Bertram, I really apriciate it. If you fell
that already provided information also should be paid, you are welcome to send
me corresponding invoice.
Closer to the topic, of course it's not C.983, but some kind of 95X, as
correctly mentioned by Hebe, but still not sure if it could be 953 or modified
952. In a week I will be in Schaffhausen for busines trip, so will try to
visit manufacture to get some info.
I will keep trying to find more information about this intersting movement and
of course will be happy to share it with forum members for free without any
discrimnation, regardless if they are collectors, sellers, buyers or any other
human being who has a passion to the watches :)
