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.
A.-L. Breguet was the first to discover, through his oscillating platinum-weight watch, a formula which would produce a reliable automatic watch. Breguet sold one of his first self-winding watches to Queen Marie-Antoinette.
