Thanks Arno - i checked my Monza caseback under better light and yes the serial number was exactly where you stated. Although a little harder to read than the model number but hey, mine does have some signs of use about it. ;-)

: Hi,
: the cal 15 Monza was a limited run to celebrate Niki Laudas F1
: Worldchampion titel.
: Possibly the rarest Monza is the Modena, I believe we have seen 3
: examples sofar.
: I have seen this watch offered on Chrono 24 for quite a while, it
: is rare to have the Modena signed dial on Cal 12.
: Therefore I think it was an exellent buy.
: On all Monzas the serial number is on the backcase underneath the
: serial number, if missing means polished away.
: Have a look at my book pages 220-230 for detailed Monza info.
: Strap was leather big holes with unsigned buckel, no stitching !
: Original box was the rare and expensive helmet.
: I have never seen any original Monza steel brachelets.
: Any detailed picture of the papers available?
: Cheers
