PROPERTY OF A GENTLEMAN
On 10 November 1801, horological legend Abraham-Louis Breguet (1747-1823) received a patent for his ingenious tourbillon invention. Breguet designed the tourbillon (or whirlwind) to compensate for fluctuations and errors in time measurement caused by the position a watch is placed in. For example, watches with traditional movements may keep excellent time when resting on a desk horizontally, but when that same watch is placed vertically in a pocket, gravity affects the frequency or rate of the escapement and thus its accuracy.
For examples of the Breguet Tourbillon watches, please see Lots 2333, 2336, 2573, 2576 and 2578 in this sale.
