Grand Sport Tourbillon - Pursuit

STREAMLINED BODYWORK

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. The timepiece weighs just 118 grammes, with a diameter of 44mm.

The Grand Sport Tourbillon is mainly comprised of satin-brushed elements embellished with numerous mirror polishes. With a circular satin-brushed finish, the cushion-shaped bezel features contrasting mirror-polished flanks. Similarly, in an interpretation of a barrel shape, the middle case also features a play with several finishes. The top has a vertical satin-brushed finish, while the profile has a horizontal satin-brushed finish and features contrasting mirror-polished flanks. In keeping with the rest of the LAURENT FERRIER collection, all the components in the case are designed harmoniously.

The bracelet is made up of rows of 3 links, with a vertical satin-brushed finish. The central links feature bevels with a contrasting mirror polish. These details give the bracelet and case ensemble a vibrant appearance.

A HIGH-PERFORMANCE ENGINE

The new Grand Sport Tourbillon features the Grand Prix d'Horlogerie de Genève (GPHG) winning LF619.01 movement, 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. 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. 

AN ODE TO PURE, TRADITIONAL ELEGANCE

The bridge of the tourbillon carriage is meticulously decorated by hand. In addition, the movement features numerous hand mirror polishing and 30 hand-crafted internal angles.

While the Grand Sport Tourbillon Pursuit appears contemporary, it also perpetuates the watchmaking traditions so dear to LAURENT FERRIER.
