The name of this exhaust comes from its inventor, Louis Gabriel Brocot, a 19th century Parisian watchmaker. It is characterized by two half-rollers of metal instead of the anchor pallets.
As early as 1826, he exhibited a movement with rake bells and the resting exhaust, which he patented in 1840.
Achilles, his eldest son born in 1817 and died in 1874, improves his father’s exhaust by adding an automatic plumbing device and especially the famous Brocot spring suspension. He filed numerous patents between 1858 and 1865.
The Brocot exhaust system is frequently located at the front on the clocks, at twelve o’clock on the dial.
