Zenith was founded in 1865 in Molocco, Switzerland, by Georges Favre-Jacquet.
In the beginning, it used the name Fabrique de Billodes.
Later, it adopted the name Zenith, inspired by the highest point in the sky, a symbol
of excellence.
By the end of the 19th century, it was already standing out in chronometry competitions,
launching its first pocket chronograph in 1899 and receiving a gold medal at the Paris
Universal Exposition, 1900.
During the 20th century, calibers such as the 135, 0 and 5011K set records and won thousands
of precision awards.
Zenith Caliber 19 NVSI belongs to Zenith's line of 19 Linear Pocket Watch movements produced
approximately between 1915 and the early 1920s.
