Watchmaker: Jean Rousseau Swiss

Not on view

Constantijn Huygens wrote to his brother, the brilliant mathematician Christiaan Huygens, from Geneva on January 5, 1650, that he had just bought a watch "á la mode" with a case of rock crystal that permitted a view of the movement such as one would see if the case were made of ice. Indeed, Geneva was well-known for its rock crystal watchcases made from a local source of the mineral. The movement of this watch has a verge escapement, and it is probably the product of the younger Jean Rousseau, a son of a master clockmaker in Geneva and the great-grandfather of the philosopher Jean-Jacques Rousseau.
