Ernest Guinand (died in 1879) of Le Locle was a gifted tourbillon maker like his peer Auguste Grether (1817-1879) of Ponts-de-Martel. Both men worked for a number of firms in Le Locle and La Chaux-de-Fonds. Guinand probably produced his first tourbillon around 1865; his very first one - no. 1060 - was later sold to Girard Perregaux and he is said to have sold as many as 25 tourbillons to this company.

Célestin Prost worked as a jeweller and watchmaker from about 1855 to 1895 in Vevey, a town on the north-eastern shore of Lake Geneva. Prost presented a pocket chronometer at the World Exhibitions in London and Paris in 1867.
