Yes, the dial without the "Swiss" may be rare, but I'm not sure that this translates into value for the collector. I can't think of other instances in which these little errors / misprints on the Heuers attract a premium in the market.

We see another of these OnTheDash, with the Mark 3 shown below.

It's a nice watch, on its own merits, but I just don't see the "No Swiss" adding value. I may be wrong . . . we'll see if we see this one or others in the market.

: 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?
