Charles Edouard Jacot\'s career in watch making began when he was merely 17. He visited Le Locle where his uncle, Abram Louis Perrelet, lived and worked. At the age of 19 he visited his cousin, the son of Abraham Perrelet, in Le Locle and became more involved with watchmaking. • The next year, in 1837, Jacot went overseas to help another uncle, Louis Matthey, in his watch case repair workshop in New York City, where he was to stay for 20 years. This shop also imported and repaired watches, where Jacot’s work expertise was most utilized. Matthey had already come to the States to set up his shop in 1825, though in 1839, he sold most of the interest in the firm to Jacot and George Courvoiser. Both Matthey and Jacot continued working for the firm until Charles left in 1857 and moved back to Switzerland. • He was a prolific inventor and innovator, especially of escapement work. Jacot invented a modification of the duplex escapement with a jumping seconds hand, known as the “Jacot Duplex”, used extensively in watches made for the Chinese market. While in America, he registered 12 American patents for perfecting the construction of watches. The stop-watch feature was patented on June 8, 1858, by which time Jacot had already returned to Switzerland.
During the 20 years that Jacot spent in the Unites States, he began a practice that continued throughout his life; the registration of American patents, 12 in all, for perfecting the construction of watches. The first came in 1840 for a duplex escapement. Another was granted in 1852 for an escapement with an escape wheel in the shape of a three-pointed star with 3 vertical impulse pins placed on small platforms between the points; this influential escapement was able to beat 21,600 times per minute. He later registered patents for a ¾ plate movement, watch key, and various winding mechanisms. • After Jacot\'s return to Switzerland he founded the company of Jacot & Salzmann in La Chaux de Fonds. By 1876 the firm was renamed \'Charles E. Jacot\'. He would then continue his theoretical research including a proposal to replace the epicyclical edges of wheel teeth with edges cut from the arcs of circles. He also made modifications to the stop-tooth of stop works that increased the number of turns of a barrel without changing the number of teeth in the Maltese cross.
Charles E. Jacot was one of the founders of the Intercantonal Societies of Jurassian Industries along with Longines.
Jacot\'s elder years were difficult as he suffered a disablement that left him paralyzed and unable to continue his already invaluable research, and later died just before the turn of the 20th century.
Charles Jacot died in August 1897.
