Product Description

Sigismund Rentzsch had a workshop at St. James Square and was appointed maker to the royal court; he was also one of the most renowned members of the London Clockmaker's Company. In 1813 he obtained a patent for a much-admired automatic chronometer (i.e., a keyless watch).
Rentzsch was born in 1776 near Strehla on the river Elbe in Germany; he moved to England between 1804 and 1811, where he became an English citizen on May 18, 1811. Rentzsch trained watchmakers such as Giles Coates, who later worked for Benjamin Louis Vulliamy. Pierre Frédéric Ingold also worked for Rentzsch. He died in 1843.
