Patek Philippe Serial Numbers...
My husband and I are joining the ranks of Patek Philippe collectors driven by the birth of our son.
How do you validate authentic Patek Philippe watches.
For example: I am looking at a 5120G in the pre owned market. There are several reference numbers on the documents that are available with the watch. I can locate the movement number on the watch and I see that it matches the number on the document. But where for example do you locate the "case number" on the watch to verify that that number matches?
