**Jean-Adrien Philippe** was a French watchmaker.

Jean-Adrien Philippe was born [[1815]] in Bazoche-Guet (France), the son of a watchmaker. He was selected as the second partner of [[Patek, Antoine Norbert de|Antoine Norbert Count de Patek]] after whose cooperation with the co-founder of the company [[Patek Philippe]], the watchmaker Francois Czapek, had failed. (The company was then called //Patek, Czapek & Co.//.)

Jean-Adrien Philippe had already enriched the watch history by a new revolutionary invention the [[crown winding]], developed by him [[1842]]. This invention earned him a gold medal at the Paris Exposition of [[1844]]; it was patented [[1845]]. On said exhibition he met Antoine Norbert Count de Patek, who recognized his talent and made him shareholder with a third of the company.

From January 1, [[1851]], his name was included in the new company name [[Patek Philippe]].

With the death of Count de Patek in [[1877]] Jean-Adrien Philippe took over the sole management of the company. [[1889]] Patek Philippe patented a mechanism for a [[perpetual calendar]], which did not require manual correction. In January [[1891]], three years before his death, Philippe transferred the management of his son Joseph Emile.

Jean-Adrien Philippe died on January 5, [[1894]] in Plainpalais in [[Geneva]].
