: This style of dial is usually found in the 11063 case, the thick
: case which was the last Autavia model. However, the dial was
: also used in the 11630 case - which you can see in the the 1978
: catalog (I think this was the first year) and then in later
: catalogs. What is quite weird (I never noticed it before) is
: that in the 1981 catalog, there is an 11630 case with this dial,
: and a 11063 case with the more standard - and older - dial.

: Anyway, coming back to your watch, it is true that this style of
: dial was not used in an 1163 case, which is what the photo looks
: like. Perhaps the dial was switched by Heuer at service, but in
: any case it is a really nice watch. If it bothers you, you might
: be able to find an 1163 style dial and hands, they are not so
: rare. Maybe a trade for your dial and hands which look to be in
: nice condition. But anyway the watch looks great, enjoy.

Many thanks for every ones input. I stand corrected, so it seems I have a unique watch then, although not original, I like it as it is.
