Greubel Forsey Launches A New Expression Of The Balancier 3
Greubel Forsey presents a new edition of the Balancier 3, limited to 22 timepieces, continuing the evolution of the movement first introduced in 2023. Housed in the Convexe titanium case measuring 41.50 mm across the caseband, this edition introduces a finishing never before executed at the Atelier: a frosted titanium bridge hand-finished with a steel brush across its entire curved surface. Enhanced contrasts and multiple hues of blue further emphasise the purity of the movement, offering a renewed interpretation of the Balancier 3 while preserving its mechanical identity.
