Here are a couple of links with some information, along with a ton of nice pictures
of the Heuer Autavia 1163T Siffert. Thought that it would be fun for fans of vintage
watches, Heuers, as well as watches in general to see, and learn about.
This version is an MK4 from 1971 with a Cal. 11 movement, but now evidently has
the MK6 dial with the hour counter now having the numerals 1-12 within it. In addition
to the movement, and dial, there are some very cool hands, and markers, as well as
a beautiful case to see on this Heuer.
You can even learn about Jo Siffert, the Swiss Racing legend, and Heuer fan too, right
here below. ..Enjoy..http://heuerville.wordpress.com/2012/05/12/autavia-1163t-siffert/http://blog.perpetuelle.com/watches/heuer-autavia-1163t-siffert/
