Lutz Brothers
The company Lutz Brothers in Le Locle was founded around 1850 by the brothers Louis Lutz (*1815, +1873) and Auguste Lutz (*1810, +?). It was considered a manufacturer of high quality pocket watches. They supplied highly refined movements very similar to the calibers of Louis Audemars to the USA and England, where they were encased in high quality American and English cases.
