Good evening, dear Users,
My mother in law showed me today three watches belonging to her late husband. Two of them are Audemars Piguet, probably daring back to the Sixties (?), at least one of them bought in Zermatt, Switzerland.
They both have serial number on the back.

Although not for sale, we would be interested in identifying them - years, movement, model. Could you please give a help or point me in the right direction?

Thank you from the both of us,
Marco, NW Italy.

Sixties is in the ballpark, they won't have model names like they do today. The second one possibly has the AP cal 2003 ultrathin (1.64mm). AP used to provide data for free but they charge for an extract now. Shoot them a note with photos and serial numbers and see what they say.

Thank you, will do!
