Jean-Louis Richter (1766-1841). Learned his art under David-Etienne-Roux and Philippe-Samuel-Théodore Roux. His work, often unsigned, is clearly recognizable. Richter applied his art principally to watch cases and snuff boxes largely destined for the Chinese, Turkish, British and Italian markets. This watch watch was previously sold in the Lord Sandberg sale.
