Grand Sport Tourbillon

Calibre LF619.01
The Grand Sport case is driven by the exclusive in-house movement developed, assembled and adjusted by Laurent Ferrier and which forged his reputation as an exceptional watchmaker. This calibre features a tourbillon device based on the principle introduced by Abraham-Louis Breguet in 1801, and complemented for the first time by a double hairspring. The major advantage of this construction is its ability to keep the balance centred on its axis, while compensating for the effects of gravity and thereby guaranteeing the extreme reliability of the rating system.
