After 1825, clock-makers produced pieces which reflected the romantic period some with lovers, naked ladies or others looking like mini-cathedrals as well as mysterious clocks with concealed movements. Most of them relied on the co-operation of case makers, enamellists, founders and chiselling specialists.
Robert Robin was Queen Marie Antoinette's favourite clock-maker. Born in 1742, he invented new mechanisms and provided the King with some extraordinary timepieces. After the Revolution he designed an astronomical repeating decimal clock for the National Convention.
Antide Janvier was also a famous inventor. Born into a family of clock-makers (his ancestor Charles started his career in Blois in 1621), Antide, born in 1751, produced at 13 a moving celestial sphere which was presented to the Academy of Besançon. After coming to Paris in 1771, he made several astronomical clocks, which are now much sought by collectors.
