The following inscription is found at the head of the score:
The Tourbillon is a mechanism in mobile timepieces which oscillates a rotation back and forth around the watch spring, providing an even distribution of gravitational force across the mechanism. This very precise and costly mechanism allows for the maintenance of time precision in both wrist and pocket watches regardless of their orientation relative to the Earth’s gravitational pull.
