In 2009, Patek Philippe created a new quality benchmark for its mechanical timepieces: the Patek Philippe seal. This new emblem of horological excellence goes beyond any existing standards of the Swiss watch industry. Uniquely, the Patek Philippe seal applies to the completely assembled watch as delivered to its owner. In conjunction with these standards, the seal represents a commitment to lifelong servicing and restoration for all timepieces created by the firm since 1839.
