Spring-driven pendulum clock by Isaac Thuret, c.1670.

An early example of a pendulum clock made by Isaac Thuret (d. 1706), clockmaker to King Louis XIV (1638-1715) of France. The first commercial pendulum clocks were made in the Netherlands in 1657, under a licence or 'privilege' according to the designs of Christiaan Huygens (1629-1695). Huygens moved to Paris in 1666, where Thuret made pendulum clocks under his direction. This clock is similar in appearance to Dutch clocks and it has many Dutch-type features, such as a going and striking mechanism driven by a single spring.
