"Of Dutch origin, Biesta is recorded as working in Paris from 1754-1789 and had already made his name before becoming a maitre in France in 1759. In 1757 he presented a clock"a aiguelles concentriques" to the Academie Royale des Sciences and in 1769 produced a watch with independent escapement." - https://www.richardreddingantiques.com/artists/246-jean-biesta/works/9702/, 10.12.2017
