Greubel Forsey has pushed beyond the previous limits of watchmaking, with no fewer than six major inventions, and a focus on ground-breaking inclined tourbillons. Now it’s time to reinvent the horological complication in the original sense of the term, and to show that in this area as well, watchmaking is in a perpetual state of evolution. The technically and ergonomically innovative Double Balancier 35° and GMT provided the springboard for this new take on the time-honoured perpetual calendar.
The QP à ÉQUATION in white gold measures 43.5mm in diameter and is 16mm high. It includes a fourth patentthe 24-second Tourbillon inclined at 25°, . The balance oscillates at 21,600v/h and the power reserve is 72 hours from two fast-rotation superimposed barrels that feature protection against excess tension. This leaves space for a large free-sprung balance. The movement diameter is 37mm(16.41 lignes), height 9.55mm and comprises 570 components and 65 jewels.
