File:Huygens first pendulum clock.png
Summary
The first pendulum clock, invented by Dutch physicist <a href="https://en.wikipedia.org/wiki/Christiaan_Huygens" class="extiw" title="wikipedia:Christiaan Huygens">Christiaan Huygens</a> in 1657, and built by clockmaker Saloman Coster. This drawing is from Huygens' 1658 treatise on the clock, Horologium. The pendulum was driven by a <a href="https://en.wikipedia.org/wiki/verge_escapement" class="extiw" title="wikipedia:verge escapement">verge escapement</a> mechanism, so it had a very wide angle of swing compared to modern clocks, perhaps 80° to 90°. The clock was weight-driven, using an ingenious arrangement of two weights linked by a loop of cord. In order to "wind" the clock, the larger weight was simply lifted to the top.
