1956 Eberhard Extra-Fort Ref. 14010 in 18K gold, presented in 1956 to Georges (Alfred Georges Henri) Guignard (1892-1963), bourgeois of L'Abbaye in the Vallée de Joux, by Dépraz & Cie (today Dubois Dépraz, supplier to Patek Philippe, Rolex, Breitling, and Richard Mille) for his 20 years of service from 1936 to 1956. Worn by Guignard for approximately 7 years until his death. Original certificate of guarantee dated May 28, 1957, accompanies the watch. The watch houses the cal. 14000 column wheel chronograph movement.
I’ve written the company to see if he worked on the Dépraz 13 3/4 chronograph calibre
