Ernest Guinand (c. 1810-1879). Guinand was an important Master Horologist from Le Locle, who, along with Auguste Grether from Ponts-de-Martel (1817-1879), specialized in the production of tourbillon carriages. According to the records of the Neuchatel Observatory, Guinand's production of tourbillons began between 1865 and 1867. He designed three models of Tourbillon carriages, always based on an A-shaped frame. He worked for several important makers, including Girard-Perregaux and Montandon. Most of Guinand’s carriages 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. In 1864 Patek Philippe chose him to build their first tourbillon regulator.
