Time in the Breguet style
A.-L. Breguet's historic invention, the tourbillon regulator, was patented in 1801. This device was conceived to compensate for the errors in rate caused by the constant changes in the watch's position. It consists of mounting the escapement and sprung balance in a mobile carriage which rotates on itself with utter regularity. Errors are thus reproduced regularly and cancel each other out, rather than accumulating. Two centuries later it remains a technical "tour de force" of which very few watchmakers are capable.
