The architecture of the Grand Sport case evokes the elegant, timeless curves of racing cars. In grade 5 titanium, the GST Pursuit illustrates the feeling of lightness experienced by drivers when they see the pink sky during an exciting race. In 2010, Laurent Ferrier won the “Men's Watch” prize at the Grand Prix d'Horlogerie de Genève (GPHG) for the Classic Tourbillon. The watch was equipped with an ingenious hand-wound movement featuring a tourbillon and a double balance spring. The new Grand Sport Tourbillon features the same LF619.01 movement, albeit presented with a more contemporary finish.

The double-balance-spring tourbillon carriage, visible through the sapphire crystal case back, is worthy of the most efficient motor engines. The complex mechanics of the tourbillon movement is a tribute to centuries-old craftsmanship.

When Abraham-Louis Breguet patented the tourbillon in 1801, his invention countered the unfavourable influence of gravity on the pocket watch's regulator when held in an upright position. By equipping the balance wheel with two head-to-tail mounted balance springs, the lateral displacement of the balance wheel axis is also neutralised. The integration of the two systems brings the respective benefits together, providing excellent precision and a power reserve of more than 80 hours.

Chronometry enthusiasts will appreciate the precision and superior performance of this timepiece, with a beauty matched only by its precision.
