Notes

Property of an Important Watch Collector, Original Owner 
The name Perrelet is associated with significant horological inventions. To name a few, Abraham-Louis Perrelet (17291826) developed the automatic movement in 1770. Heir to his grandfather’s watchmaking genius, Louis-Frédéric Perrelet (1781-1852) invented the split-seconds mechanism in 1827. Perrelet’s calibers, entirely crafted, decorated, adjusted and assembled within in-house workshops. Be it a traditional automatic caliber, a patented double rotor movement, or a tourbillon, the brand offers comprehensive possibilities. This lot echoes Breguet’s first tourbillon which was a one minute tourbillon, housing a cage that is starting and stopping six times a second, 360 times a minute. This requires the use of a strong mainspring. In short, the cage should be as light as possible. This lot in black DLC comes in pristine condition, is rarely worn by the original owner, is certainly a chic piece to be observed on one’s wrist.
