The tourbillon, A.-L. Breguet's historic invention patented in 1801, was conceived to compensate for rate errors resulting from the effect of gravity on the moving parts.

Breguet developed in 1820 an observation chronometer. It permitted the precise measurement of intermediate periods, thus anticipating the modern chronograph.
