With the launch of the Balancier QM, Greubel Forsey introduces the first timepiece to officially bear the Qualité Musée (QM) standard — a designation that formalises the extraordinary level of hand-finishing and craftsmanship that has defined the Atelier since 2004. Developed with the support of the brand’s Experimental Watch Technology (EWT) Laboratory, the Balancier QM combines understated elegance with uncompromising watchmaking excellence. Housed in a refined 39.6mm white gold case, the hand-wound timepiece displays hours, minutes, small seconds and a distinctive power reserve indicator, while showcasing the exceptional artisanal finishing that has become synonymous with Greubel Forsey. Produced in a limited edition of just 33 pieces, the Balancier QM represents a new benchmark in haute horlogerie.
