isochronism
isochronism (aɪˈsɒkrənɪz(ə)m) [f. as isochronal a. + -ism: cf. Gr. χρονίζ-ειν to spend time, continue in time. Cf. F. isochronisme (1735 in Hatz.).] 1. The character or property of being isochronous, or of oscillating or taking place in equal spaces of time.1770 Gentl. Mag. XL. 416 Nothing seemed to...

Conical pendulum
This property, called isochronism, is shared with ordinary pendulums and makes both types of pendulums useful for timekeeping.

Fusee (horology)
This problem is called lack of isochronism. Many parts were gradually improved to increase isochronism, and eventually the fusee became unnecessary in most timepieces.

Anchor escapement
In addition to the improved accuracy due to isochronism, this allowed clocks to use longer pendulums, which had a slower 'beat'. The superior performance of the deadbeat over the recoil is due to improved isochronism.

Linear approximation
This property, called isochronism, is the reason pendulums are so useful for timekeeping.

Verge escapement
This is called lack of isochronism. In pendulum clocks, the wide pendulum swing angles of 80°-100° required by the verge cause an additional lack of isochronism due to circular error.

Galileo's escapement
The pendulum, due to its isochronism, could be a much better timekeeper.
