GREUBEL FORSEY Balancier Convexe S² No. 5/88

Greubel Forsey presents the Balancier QM – the first timepiece to meet the “Qualité Musée” standard. Since 2004, the atelier has subjected every watch to an uncompromising level of hand-finishing, which, although uniformly applied, has never received an official name. With the Balancier QM, this standard is now finally christened: “Qualité Musée”. Limited to 33 pieces and featuring a 39.6 mm white gold case, the Balancier QM is the first expression of a discipline that will now be driven by a specially established research department within the Experimental Watch Technology Laboratory.
