The model number of Patek Philippe is on the certificate of the watch. If there is no certificate, you can only open the back cover. Generally, the model number is engraved on the back cover of the watch.
The authenticity of a Patek Philippe watch can only be determined by looking at the movement inside. The workmanship and craftsmanship cannot be deceived. The case only has the case number, and the movement plywood only has the movement model. In addition, you can go to Patek Philippe’s official website to view its model number.
Patek Philippe believes in the philosophy of fine products, adheres to the production principles of focusing on quality over quantity, careful workmanship and slow work, and strives for perfection. It pursues limited production, with an annual output of only 50,000 pieces. For more than a century and a half, Patek Philippe produced a very limited number of watches (only 600,000), less than the annual output of one fashion watch, and it was only sold in the world's top famous stores.
How to tell whether a Patek Philippe is authentic or fake;
1. Look at the workmanship of the watch. This is very important. Patek Philippe watches with tens of thousands or millions of dollars are very fine in workmanship. In the pursuit of perfection, watch beauty is everywhere, even under the invisible case. The hand-polished connections, corners, and beautiful circular textures on the movement are all Patek Philippe details, but they are also carefully crafted.
Currently, Patek Philippe is still the only manufacturer in the world that adopts manual refining and can complete all watchmaking processes in the original factory, and adheres to the traditional craftsmanship of watches. A fake Patek Philippe has rough workmanship and can be distinguished at a glance.
2. Most of the patterns and letters engraved on the back cover of counterfeit Patek Philippe watches are very thick and blurry, and the case number and movement number are unknown. Original Patek Philippe watches usually have a film on the back cover. Gold-plated shell watches made in Switzerland have letters engraved on the open position of the case (opposite to the spring rod where the strap is installed), such as PLAQUEGI0, indicating that the case is 10 micron gold-plated.
