Laurent Ferrier Grand Sport Tourbillon Iceberg LCF044.T1.C3GC1 Inspired by the intense freshness of eternal snow and pack ice, the Grand Sport Tourbillon Iceberg brings an unusual serenity to the wrist. Its opaline dial gently absorbs and softly releases light, revealing a delicate pale shade touched by subtle blue reflections. Conceived for aesthetes who appreciate a luxury that is discovered rather than displayed, this lightweight Grade 5 titanium timepiece reserves the mechanical poetry of its hand-finished tourbillon calibre exclusively for the wearer. 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.
