Tourbillon | Invented by Abraham-Louis Breguet in the 17th century, the tourbillon is a rotating cage that houses the escapement, which turns in an anti-clockwise direction to counter the effects of gravity on timing precision. While vital to the accuracy of pocket watches, tourbillons today remain a sought-after complication that tests a watchmaker’s technical prowess. |
