... and 9-90 is the movements "name".
Caliber is the technical term and horological lingo for the movement.
It is engraved into the movement, if you carefully open it you will see. But mostlikely, due to the production year, it is a 9-90.
Regarding the rule about value discusions: Fair enough not to speak about discounts at the AD (sorry, another lingo= authorized dealer ) !
BUT here are MAYOR POSTS about auction results,like the one that reports how much the Sterns have paid at an auction recently to get a time piece into there own museum back ???
Do not know why this is accepted ???
Back to your lovely beauty: it is a rose ! No doubt, as it is quite decently functioning.
Ask Patek for a quote, but I believe it makes financially sence ...

Moritz
