The tourbillon is a mechanical device
consisting of a carriage containing the
watch’s regulating system and perfor-
ming one complete revolution per minute.
It is designed to improve the accuracy of
mechanical watches by offsetting disrup-
tion of the balance wheel isochronism by
the earth’s gravity. A flying tourbillon is a
device that is only supported by its infe-
rior components.
