Thanks again Jeff, and all the other 'respondees'.

This is fascinating stuff, and pulls you in to the rich history of these watches. It never fails to amaze me how these old Heuers have such a varied and wonderful past.

I have had a good read of the Cal 11 vs 11-I and I am 100% sure the watch I'm looking at is a Cal. 11-I.

One query, in the MOAT, there is 1163 MH model black dial, white subs, listed as Cal. 11 (the 2nd 1163 listed)...
Is this a Cal. 11-I?
Does this model have red accents (like the Viceroy)?

Cheers
Stewart

: You should never find the Viceroy shown below with a Cal 11
: movement; it should always have Cal 11-I or Cal 12. As we have
: discussed previously, many Cal 11 movements may have been
: removed from watches, and replaced with later movements. Then
: the watchmaker may have worked on the old Cal 11 movement,
: gotten it running properly, and dropped it back into another
: watch. But Heuer would not have used a Cal 11 in any Viceroy.
