Comprehensive Quality Assurance.
What does the Patek-Philippe Seal promise? You can find out more about the seal of approval and 3 quality pledges that apply to each award-winning watch in this article.
After many years of common history, the paths between the Geneva seal and the most prestigious Geneva manufactory are separated in the year 2009. Since then Patek Philippe has been subjecting his own strict rules to his watches. With the introduction of the Patek Philippe Seal in Spring 2009, the Geneva Manufactory is adopting its own quality seal after over 100 years of the Geneva Punze. The rules of this seal apply to all mechanical watches of the manufactory, irrespective of their degree of complication. The Patek-Philippe Seal not only refers to the movements, but judges the clocks as a whole. This also includes equipment parts (housing, dials, pointers, pushers, bracelet webs and so on) as well as the aesthetic and functional aspects of the finished timepiece.
Quality Promise #1: accuracy of gait
Keyword timepieces: The speed accuracy of a patek-Philippe Watch is controlled during several stages of production, only for the movement alone and then also in the switched-on state. The final control of the medium accuracy is carried out on a supporting simulator and must comply with the following precision standards: for calibres with a diameter of 20 millimeters and more, the accuracy of the gear must move in the range of minus three to plus two seconds per day . For calibres with a diameter of less than 20 millimeters, the required accuracy is in the range of minus five to plus four seconds a day. For watches with tourbillon, the accuracy of the gear must move in the range of minus two to plus one second per day.
In the case of the latter, the largest individual deviations in the six control positions of the watch and the mean deviation may not exceed four seconds per day. The gait accuracy of tourbillons is confirmed by an individual ticket that is delivered with the watch.
Quality Promise #2: casing processing and waterproofing
The quality requirements apply to all equipment parts, in particular the housings. For example, for the housing production in the traditional cold forming process, where massive metal ingots are pressed into the desired housing form under tons of heavy pressure. The dies used for this purpose consist of matrices and dies, which are manufactured in their own tool studio on thousandths of a millimeter precisely from extra-hard tool steel. The further steps of the housing production are just as meticulous as the manual fine work and the repeated measurement. At the end, each case is polished by hand. This requires two hours of concentrated work for a simple steel casing and up to six hours for a complex platinum enclosure. The water resistance test is carried out both in the air under pressure and in the water, with the watch being subjected to pressurization from three to twelve bars depending on the watertightness of the water.
The question arises as to who controls compliance with the criteria of this seal. Patek Philippe installs various self-monitoring bodies independent of the Organization: the» Comité du Poinçon Patek Philippe «Defines the rules for the seal and adapts the regulations strategically to the technical Further developments. The panel consists of the two subcommittees: the» Comité technique «is responsible for technical issues and the» Comité Esthétique «For the aesthetic aspects.
Compliance with the rules of the Patek-Philippe Seal is to be continuously monitored in all workflows. These tasks are the responsibility of the Commission de Surveillance (Supervisory Commission) as an executive body, which is staffed independently of the Comité du Poinçon Patek Philippe. It is used daily and reports to the Comité du Poinçon Patek Philippe. As the supreme authority, the President of the Manufactory functions as guarantor of the Patek-Philippe Seal.
Quality Promise #3: Lifetime service
The Patek Philippe Seal defines the quality requirements from the start of production to the delivery and is considered the first seal of approval of the watchmaking industry also for the service for life time. Patek Philippe guarantees the service, maintenance and restoration for all Patek Philippe watches that have been manufactured since the company was founded in the year 1839.
What quality seals for watches are there yet?
In addition to the Patek Philippe Seal, there is the Geneva Punze, also known as the Geneva seal, the chronometer test, the Metas Certificate of Omega and the qualité Fleurier.
