Another famous maker was Julien Leroy, born in 1686 into a family of clock-makers whose ancestor Jacquemart was already producing clocks in 1404. He also designed many inventive models.
Gilles Martinot, born in 1622, produced elaborate clocks for the French court. His son Henri made a piece in the shape of a celestial globe, which indicated the movements of the sun, and of the moon as well as an 8-day repeating clock. Jérome Gaulard, also of the Martinot family, who worked during the second half of the 17th Century, also produced some interesting timepieces, including an impressive clock indicating sunrise and sunset, the days of the month and world time dial with moving celestial spheres for which he received 500 gold coins from the King in 1701.
Another great maker of the Martinot dynasty was Balthazar the Elder, born in 1636, who worked for the Queen and produced repeating clocks.
One of the first known makers was Pierre Merlin, who worked for the King of France in 1372. One of his clocks worked during 400 years until the church tower in which it was installed was destroyed in 1813.
In 1689, Louis XIV's son, heir to the throne of France, possessed ten clocks including one gilt silver piece inlaid with diamonds and rubies. In 1787, King Louis 16th had 161 clocks while his wife Marie-Antoinette possessed 45 pieces.
