Jeanrenaud, Eugène, Swiss watchmaker
There are several watchmakers with the name Eugène Jeanrenaud, such as Eugène Jeanrenaud (1892-1968) who worked for Longines. The world clock shown here is possibly about Eugène Jeanrenaud from the Val-de-Travers near Neuchâtel. He was born around 1850 and was married to Julie Aurélie Junod. The son Charles Edouard Jeanrenaud was born on March 21, 1870, and also became a watchmaker.
