What is the Patek Philippe Extract from the Archives?

John Reardon explains the Patek Philippe Extract from the Archives and why this piece of paper is so important to all Patek Philippe collectors. Each Extract from the Archives is in effect a birth certificate of the watch it describes, a form of block chain that gives valuable information about key aspects of each watch. The Patek Philippe Archives give access to information about every watch made since the start of the company in 1839. It is one of the reasons that Patek Philippe watches are so coveted as each Extract completes a watch's story and gives collectors confidence in what they are buying.
