Audemars Piguet Case Dating and Identification

Model identification

Every Audemars Piguet watch has a movement number engraved on the mainplate, generally next to the balance, and a case number which is engraved on the outside of the case-back. In the example picture: Number 25 is the sequential number of these particular model/reference. D67746 is the case number, sequential across all watches manufactured by Audemars Piguet. There is no certain way to tell the age of an Audemars Piguet , but certain estimates can be made with the case number: there are 100,000 watches with the same letter, and AP manufactures 20,000 watches a year (VERY aproximately) so that the letter of the serial number changes aproximately every 5 years. A known fact is that production of the F series started sometime in 2004. In the example watch with case number D67746: D started in 1994, plus 1 year per 20,000 on the case number will make this watch a 1997-98.
