The "tourbillon", 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 watch balance will go fast or slow depending on the position of the watch. Breguet solved the problem by rotating the entire balance and escapement about their common axis once a minute, averaging out the positional errors by the constant rotation. Breguet received a patent from France's ministry of the interior for "a new regulating device known as the tourbillon" on 26 June 1801. The document was dated according to the republican calendar of the time, 7 Messidor, Year IX.
