Antoine Léchaud
1812 - 1875
Swiss watchmaker.
A specialist in Swiss lever escapements for watches, he collaborated with his brother Jean (1815-1844), and with Georges-Auguste Leschot. Lechaud and Leschot worked together to perfect the lever escapement which, manufactured industrially from the early 1840s, improved precision and reduced production costs.
