The present watch incorporates Fasoldt's double-wheel lever escapement, patented on 1 February 1859. The remarkably reliable system does not require oil and has a very strong draw on both locking pallets. It furthermore features his patented micrometric torsion regulator.

Charles Fasoldt (1818 Dresden, Germany - 1898 Albany, NY) was together with Albert Potter the most renowned American watchmaker. In 1848, he narrowly escaped the death penalty for his part in the revolution by escaping from the prison where he was held. He then emigrated to the USA where he opened a watchmaking company which also made precision medical instruments. Following his move to Albany, NY, in 1860, Fasoldt further perfected his technique and became increasingly successful. One of his first watches, serial number 26, was made for General Armstrong. Fasoldt watches sold for between 150 and 300 dollars, a considerable sum at the time, but the middle classes paid willingly. All watches were designed by Fasoldt himself and the majority were fitted with his lever escapement, patented on 1 February 1859: Patent no. 16652 for a chronometer escapement with a hitherto unseen feature: a double-wheel lever escapement. Although called "chronometer escapement", Fasoldt's invention is in fact a lever escapement with two escape wheels, the smaller one giving impulse in one direction and the larger one in the other direction.

Throughout his life, the prolific inventor continued to create microscopes, watches, clocks and clock towers. Charles Fasoldt died in 1898 in the city of Albany.
