You came to pretty much the same conclusions as i did Paul.
Its definately an early Cal.11 movement (albeit with with some later parts in place). The bridge plate has the rare wider spaced HEUER but the dimples that are usually only seen on the base plate are in different places to what i've seen in the past with Chronomatic movements., that makes this movement even more interesting !

Finding a case in the right serial range will be, at best, an adventure. In all likelyhood it has been melted for its gold content. I really hope the buyer is from the forum, i'd like to congradulate them on this purchase and let them know i'd love to see more of this movement / dial.

-: Yet another interesting find that helps to corroborate previous
: hypothesis and theories. There are some interesting details to
: be found - 1st generation calibre 11 movement with the dimples
: on the base plate and gold crown, hour markers and hands which
: to me indicate that this would have been in a gold case. The
: gold price has generated a whole industry in recycled gold
: jewellery. Auctions like these always have dial and movements on
: their own which suggests that the gold cases have been removed
: for their base value. I would suggest that in most cases the
: value is in the gold case however in this example the complete
: watch with correct serial number 18kt gold case would be worth
: far more than the sum of the parts. Personally, I think it will
: be rather difficult to find a gold filled case in any serial
: number let alone one that matches the chronomatic range what
: ever that may be for 18 carat gold Carrera cases.
