the/gp/chronicles: Understanding the Codification

We all know how watch manufacturers use Reference numbers to catalogue their watches and if you can decipher the codes, there is actually a lot of information that can be retrieved. Girard-Perregaux has been using a consistent system since the early 90s with a slight adaptation around the year 2000, when the Coding changed a little bit. It is now separated by dashes rather dots and in a slightly different order.

Let me share with you a 2 page document on Girard-Perregaux Codification (in English, French and German) that helps to understand the way the code works.
