Excerpt from The Watch Balance and Its Jeweling: A Lecture
The human heart beats about 65 times a minute; a balance 300 times. Thus it will be seen that a balance beats more than.4% times as fast as the human heart. The periphery of an 18 size balance, in de~ scribing its vibrations, traverses a distance of more than 9175 miles in 24 hours. This is to say that if the balance were rolled along the ground to the extent of its vibrations it would cover that distance every 24 hours.
If a track were laid around the world at the equator and an engine having six foot driving wheels were placed on this track and run till the wheels had made the same number of revolutions that the balance de scribes, in one year it would have made 28 complete circuits of the globe.
