Patek Philippe serial no. on pocketwatch

[Black Snow]

'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.

Order an extract from the archives.

Thank you for your reply.

How would I go about that and what kind of information would the extract have?

Is there any research I can do online short of that?

Appreciate your help.

This has all the info you'll need, plus the online form for ordering.

In general, you'll get a sheet of paper that shows the date of manufacture and original sale, along with some other basic info.

Delivery time is listed as 12 weeks, but the one I ordered in January arrived within 4.

Many thanks for your very helpful reply.

I'll send it out and report back if there's any interesting news.
