Pouzait lever escapement
In 1786 Jean Moise Pouzait presented his newly invented escapement to The Society of Arts of Geneve.
It was quite special escapement that featured very big balance wheel and beats one time per second.
By idea of the author, this kind of movement should be used in "dead second" watches with centre seconds.
It's known only one watch of this type, signed by Pouzait, please see illustration.
But it's known several very similar watches, signed by celebrated watchmakers - Berthoud, Hessen, Jurgensen.. and even Breguet (shown in AGAHA revue N26).
A. Chapuis in his book "La montre Francaise" says that probably all of these watches are made by workshop of Pouzait and supplied to different watchmakers
At least it's known that Pouzait executed lever escapements for Breguet. For example, Abraham Louis Breguet noted in his records in 1792 that lever escapements were ordered from Pouzair at 9 July.
