One of the hottest categories in watchmaking right now is the sport-luxe watch, with its raft of steel cases and integrated bracelets. Laurent Ferrier's take on the trend is the Grand Sport Tourbillon whose smooth curves and rounded profiles are a hallmark of the brand. Housed inside a 44mm steel case is the very same movement that took home the Men's Watch prize at the 2010 Grand Prix d'Horlogerie de Genève. The tourbillon, visible only from the back, is equipped with two reverse-fitted balance springs that neutralise the lateral displacement of the balance axis for even greater timekeeping precision.
