The Balancier collection is dedicated to timepieces regulated exclusively by one or two balance wheels, without tourbillons and without additional complications. These creations express Greubel Forsey's chronometric philosophy in its most direct form: precision achieved through geometry, energy management, and stability of the regulating organ. Each Balancier timepiece concentrates the full know-how of the Atelier on a single objective – extracting maximum performance and finishing excellence from a restrained mechanical architecture.

The Complications collection brings together timepieces integrating one or more horological complications, regulated by either a balance wheel or a tourbillon. These creations combine mechanical complexity with clarity, reliability, and finishing excellence. Information is presented with precision and coherence.

The Tourbillon collection brings together timepieces regulated by advanced tourbillon systems, without additional complications. In these creations, the tourbillon forms the structural and visual core of the movement. Multi-axis cages, inclined systems, rapid rotation, and extreme lightness are employed to improve chronometric behaviour under real-world conditions.

The Mechanical Nano collection stems from Greubel Forsey's research into nanomechanics and extreme energy efficiency. These timepieces explore reduced mass, lower friction, and novel materials to deliver high performance within minimal volumes and energy budgets.
