According to the Archives of Montres Breguet, the present half quarter repeating watch with unnumbered gold case made by Tavernier, was sold to Monsieur Thureau for the Count Sternberg on 4 June 1817 for the amount of Francs 2,128.
Kaspar Maria von Sternberg (also: Caspar Maria, Count Sternberg), 1761-1838, was a Bohemian theologian, mineralogist, geognost and botanist. He established the Bohemian National Museum in Prague and is deemed to be the founder of modern paleobotany. He was also on friendly terms with Johann Wolfgang von Goethe.
Pierre Benjamin Tavernier, the renowned case maker located in Paris, supplied his exceptional cases to the most famous watchmakers of the time, notably Abraham-Louis Breguet, Ferdinand Berthoud and others.
