Zech makes first clock with fusee In 1525, the first clock known to incorporate a fusee was made by Jacob Zech in Prague. The origin of the fusee is unknown, but it was certainly invented before this clock was made, probably some time in the 1400s, appearing with the first spring-driven clocks. Further Reading White, L.
