Lever escapement was invented in 1755 by English watchmaker Thomas Mudge.
However, in the continental Europe of late XVIII / early XIX it was still rarely used.
In 1786 Jean Moïse Pouzait (1743-1793) presented to the Society of Arts in Geneva a model of his lever escapement, one of the first on the Continent.
The attempt made by Moïse Pouzait featured a lever escapement associated with a large seconds-beating balance. Due to its spectacular aspect, and in spite if its inertia sensitivity, Pouzait's escapement was much appreciated in China, before the invention by Jacot of the so-called "Chinese duplex" ecapement, enabling the production of dead center-seconds watches.
The watch bears "presigeous" signature by Breguet & Fils, in attempt to add value to technically sophisticated watch with rare escapement.
