Patek Philippe seal
The Patek Philippe seal defines strict criteria for quality
In the spring of 2009, Patek Philippe introduced its own quality seal, the Patek Philippe Seal. The requirements for the quality of the watches go even further than the Geneva Seal. The Patek Philippe Seal looks at the watch as a whole.
Extensive criteria
The Geneva Hallmark, which ennobles outstanding luxury watches, sets criteria for the movement. The Patek Philippe seal does not stop there. In addition to the caliber, it also looks at important parts of Patek Philippe watches. These include the case and pushers, dials and hands, and much more. The seal also assesses functional and aesthetic aspects of the finished watch. It thus sets out the quality requirements from the start of production to delivery. It is considered the first seal of quality in the watch industry that also refers to lifetime service.
Extensive testing
Depending on their complexity, the finished movements are tested for up to 30 days at a time. After being encased, the complete watch is put on the test bench for up to 20 days. Here it must undergo various checks. These include tests with wear simulation as well as functional checks and precision measurements. The aim is to ensure that the final assembly was also carried out according to the rules and specifications of the art of watchmaking.
Strict standards
The average accuracy must meet strict precision standards. For movements with a diameter of 20 mm and above, the accuracy may only change within a range of -3 to +2 seconds within 24 hours. Calibers under 20 mm have an accuracy range of -5 to +4 seconds. Tourbillon watches have accuracy requirements of -2 to +1 seconds. Strict compliance with the criteria for the Patek Philippe seal is monitored by an independent committee.
