The Tourbillon 24 Secondes Architecture is unlike any Greubel Forsey timepiece ever created. Its case is wholly atypical, its construction purposeful, its components sculptural, their mechanical interplay kinetic and the movement – simply spectacular ! This new Greubel Forsey calibre within a new convex conical frustrum case shape represents a complete departure from traditional movement construction and aesthetics and brings an architectural experience to the wrist.
