Thank you for responding Stuart but I believe you mean to the Ref. 11063 as those are always showing a "V" underneath.
I have some cases with Ref. "1163" cases and others featuring Ref. "1163V".
I have some of the watches with Ref. 1163 featured a "V" and some other don't. I want to find out which models of Autavias 1163 would have the "V"?
I have checked the "Case Ref." table of this site in different Heuer models and it does not correspond to the ingravings on the cases.
This is far from being a critique just a remark.

Jeff - your answer has been very usefull and I have indeed been able to observe that this cases with 1163V are used randomly on the Autavias Ref. 1163.

I've always had an eye on this site and now my pleasure to have participated with your warm and friendly help.

Al the best for this site and members.

: This is a difficult question, and I am not sure that there is a
: simple answer.

: We see a lot of cases marked only with the "1163" and we
: see other cases marked "1163 V". I do not currently
: have enough time to check files, but I do not recall seeing any
: cases marked "1163T" or "1163MH". So this
: tells me that when we see the "Sifferts" (1163T) or
: the so-called "Derek Bells" (1163MH), these cases are
: marked simply "1163", and they should not have a
: "V".

: Later in their production, I believe that we saw the 11630V and the
: 11063V cases used for watches that were not
: "Viceroys", but I am not sure that we ever saw this
: with the 1163Vs . . . so I would say that in most instances, if
: the case is marked 1163V, then it should be a Viceroy. I expect
: that there are exceptions.

: I will check further, as time permits, but this is my quick
: reaction.
