Have a look here to see how to distinguish Cal 11 vs. Cal 11-I -- http://onthedash.com/docs/ChronomaticMovements.html The distinctions are described and shown in full detail.

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.

: Thanks Jeff,

: So, in summary - would it ever be possible that you could find a
: watch identical to the photo below with a Cal. 11 movement??
: Also, how do you identify a cal. 11-I from a Cal. 11 ??
