Patek Philippe is a true watch manufacturer meaning that they control all stages in the making of our watches, from design to production, from assembly and finish to distribution. The uniquely comprehensive nature of our production method has many important benefits. Certain traditional skills and tools, which have not changed for hundreds of years, can still be used on a daily basis. The experience and know-how of our master watchmakers is passed on to new generations. They also preserve the traditional Art of Fine Watchmaking, the criteria of which were established by the Republic of Geneva in 1886, with the creation of the Geneva Seal. The Geneva Seal hallmark is the highest official endorsement of watchmaking quality and excellence. It certifies that all our watches have been made in this tradition. Tradition should always command respect.
