The verge escapement dates from 13th-century Europe, where its invention led to the development of the first all-mechanical clocks. The usual angle between the pallets was 90 to 105,[8][31] resulting in a foliot or pendulum swing of around 80 to 100. The clock owner can accomplish this task in 10 minutes with a minimal amount of tools. Verge watches and clocks are sensitive to changes in the drive force; they slow down as the mainspring unwinds. Great reference.

[8] This is because it has proven difficult to distinguish from the meager written documentation which of these early tower clocks were mechanical, and which were water clocks; the same Latin word, horologe, was used for both. [32] This reduced the pendulum swing to around 50 and reduced recoil (below), but required the verge to be located so near the crown wheel that the teeth fell on the pallets very near the axis, reducing initial leverage and increasing friction, thus requiring lighter pendulums.[32][33].
