Isaac Soret and Vacheron & Constantin. The trade name Isaac Soret was used by Vacheron & Constantin for plain and repeating watches. It is possible that these were intended for export. The first official record of this name in the Vacheron archives is found in 1820. However, several watches from the late 18th century, including the present watch, are recorded.
