====== Patek Philippe Seal ======

{{wst>image_cr|Patek Philippe|Seal}}

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 stripes|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]].
