The Patek Philippe Seal is a company-exclusive quality mark, which the luxury watch producer Patek Philippe confers to its own watches, if they meet certain strict specifications. Formerly all Patek Philippe watches had to meet the requirements of the Geneva Seal (Poinçon de Genève), which are less strict. Since 2009 the company no longer submits its movements for inspection to the Geneva Seal Bureau.

The criteria of the Patek Philippe Seal include:

  • For calibers with diameters of 20 mm or more, the rate accuracy must be within -3 and +2 seconds per day. For calibers with diameters of less than 20 mm, the accuracy must be within -5 and +4 seconds per day.
  • Calibers equipped with a tourbillon must have an accuracy of -2 / +1 seconds in 24 hours.
  • Very strict requirements on the manual finissage of movement parts in keeping with the Genevan traditions. For example: Plates and bridges are chamfered with mirror polished edges. Visible sides of bridges are Geneva striped and inner sides are circular grained.
  • The seal also covers service for the entire lifetime of the watch and guarantees maintenance, repairs, and restoration of all watches crafted by the manufacture since 1839.
