According to the records of the Neuchâtel Observatory, Guinand's production of tourbillons began between 1865 and 1867. He designed three models of Tourbillon carriage, always based on an A-shaped frame. He worked for several important makers, including Girard-Perregaux and Montandon. Most were equipped with a pivoted detent escapement, one with spring detent and some with lever escapement. Most of his carriages were not signed and can only be identified by their characteristic A-shape.
