Christmas really comes to Geneva in January, when a host of watch brands present their new releases in the city and get a jump on the spring fair in Basel.

ThanksJohn

Patek Philippe serial no. on pocketwatch
'Evening everyone.I've come across a nice Patek pocketwatch and I'd like to know what year it was manufactured.The case number is 203514. The serial number is 85327.Is there some way to know the period of manufacture from these numbers?I've found some online resources (for example this one) but they are not that specific, and there is some contradictory information out there (for example here, in which a lower serial number is dated to a later year).Thank you to anyone who can send me in the right direction.
