Cox's clock

Drawing of the Cox clock

The Coxsche watch ( English Cox’s timepiece or Cox's perpetual motion ) is a watch developed by James Cox and Jean-Joseph Merlin around 1760, which used differences in air pressure to wind it up automatically, giving the impression of a perpetual motion machine .

The writer Christoph Ransmayr was inspired by Cox and his Perpetual Motion to write the novel Cox or Der Lauf der Zeit (2016), in which the British watchmaker Alister Cox traveled to China in the 18th century to find an "eternal" for Emperor Qianlong Clock "to build.
