So I read somewhere that the Autavia 1163 with Jo Siffert dial and word CHRONOMATIC was produced in 50 to 100 examples only.
I do not know if there are actually any factory records to prove this number.
On the other hand my newly acquired Siffert has an anomaly whereby the word SWISS is missing from the dial.
I have looked extensively over the Internet and found Sifferts with CHRONOMATIC but have not found another one with the SWISS missing.
The only example of this dial I saw was on this website. Some years ago I acquired a white gold Rolex Day Date 1802 which is quite rare and was the first one to post it on Vintage Rolex Forum. A few years later Antiquorum offered one for sale and in their write up they stated they had never seen one before.
Have any of you seen Siffert as in my pic. ? Can any one here post a pic. of the C number on the edge of the case back please?
