Robert Greubel and Stephen Forsey have been pushing the limits of fine watchmaking for many years now, tackling the challenges of complexity every day. And yet, after the Double Tourbillon 30°, the Quadruple Tourbillon, the Tourbillon 24 Secondes and many other bold complications like the Grande Sonnerie, the “Balancier” was self-evident. Greubel Forsey was bound one day to create a timepiece of great purity, featuring a unique and original balance wheel. Their creativity is immediately evident in the asymmetry of its case, which has almost become a constant of Greubel Forsey’s universe.
