Patek Philippe was established in 1851 between Antoine Patek and Jean A Philippe. This duo laid the foundation that allowed Patek Philippe to dominate the Swiss watch industry for over 150 years. In 1863 they invented the ’free mainspring’ that led to the invention of the automatic watch. The Stern family have been conscientious protectors of the virtues that make Patek Philippe the best and the status and regard of the world of connoisseurs and collectors has never been higher. Fifty of the fifty-three highest prices ever paid for watches at auction were Patek Philippe.
