This is exactly the point Jeff,
with Heuer themselves clouding the water by picturing an 1163 but then quoting it as an 11630 how are we, the collectors, suposed to dissect the information 40 odd years later. Our best chance is if more examples are brought to our attention through the forum.
Hope to see some more turn up - Darren

-: Sorry to be arriving late, and blurting out a question, without
: going through prior messages, but here is my question: The 1972
: catalog lists a 11630P, not a 1163P. [I am
: more interested in the listing than the illustration, as the
: illustration probably came from the art department, rather than
: the watchmakers.]

: By definition, the 11630 will have a mineral crystal,
: rather than a plastic crystal. Have we ever seen a 1163P in a
: catalog or any literature (price list, etc.)? On a technical
: level, do we think Heuer could have built this kind of diving
: watch with the then-existing 1163 construction (plastic crystal
: / thinner tension ring)? I don't know the answer / just asking
: the question.
