1801: the invention of the tourbillon, a solution to the challenges of gravity. 2008: Concord pays tribute to this horological tradition with a stunning new interpretation. An astounding time-measuring instrument, the C1 Tourbillon Gravity features a tourbillon housed outside the dial and outside the case in a revolutionary perpendicular mechanical concept. The position of the tourbillon enables it to serve its initial function: to negate the effects of gravity in a vertical position.
