[1] In 1842, Adrien Philippe invented a mechanism for watches which allowed them to be wound and set by means of a crown rather than a key.
[2] His patented invention earned him a Bronze Medal at the French Industrial Exposition of 1844 (World's Fair).
In 1863 he published a book in Geneva and Paris on the workings of pocket watches titled Les montres sans clef.
[4] The watch was purchased most probably by the Patek Philippe Museum though this is not confirmed and may be owned by a private collector.
The wedding between Louise and Joseph Antoine Bénassy-Philippe that the watch was presented at is noted as the wedding that saved Patek Philippe by providing the company a much needed successor to Antoni Patek for the company to survive the founding generation.
