: j.h.

the confusion created by the MOAT seems to keep coming back to haunt us...... because we had no actual data re when Heuer stopped using the cal 11 and changed to the cal 12 (and i would suspect that there was a period of time when both were used) we stuck with Heuer's movement reference and continued to describe the cal 12 as a cal 11 throughout the table (watches with cal 12 movements always have 11 as the begining of the case reference)

many of Heuer's models were introduced after the change to cal 12 so Cortina, 110.5XX Carrera, Daytona, Jarama, Monza and Verona were only ever fitted with cal 12. The Montreal, Silverstone and Calculator were introduced at the changeover period but i've never seen one that was definitely original fitted with a cal 11.

thanks to Hans for clearing up the silver bridged cal 12s. my experience is that cal 11 silver bridges would not necessarily fit gold cal 12 movements but there are so many slight variations, sometimes the centre seconds bridge was not jeweled (which i think must make it a 16 jewel movement?) an so on.

i'm also pleased that Hans has thrown his weight behind the theory that the odd (waffle) dial Monacos were not right. this still leaves the 7736 Monacos with painted (not applied) markers and no tool 033 on the back. i think these are left over supplies from a German jewelers who marketed the Monaco with their own name. i owned (bought from a dealer in Paris) and sold one of these 5 or 6 years ago and can confirm that the dial was original and had age that could simply not be faked but the dial may well have been unsigned and had the Heuer and Monaco script subsequently applied.

Answers on a post card please?
