Greubel Forsey Unveils the Balancier QM

Since its creation in 2004, Greubel Forsey has pursued an absolute quest for perfection. Every timepiece designed by the manufacture is conceived as a demonstration of the highest level of artisanal execution, where each component, visible or invisible, receives extraordinary attention. With the Balancier QM, the house now takes a new step by finally giving this philosophy a name: Qualité Musée.

Far more than a new watch, the Balancier QM introduces a standard meant to guide the atelier’s future creations. An approach that goes beyond mere aesthetic pursuit to make each piece a true work of mechanical art.

The official birth of Qualité Musée

For more than twenty years, Greubel Forsey applied an exceptional level of finishing to all of its timepieces without ever formalizing it. Now, this standard has a name: Qualité Musée.

This name reflects the manufacture’s determination to produce watches whose every component could be displayed like a museum piece. It also draws on the work of the Experimental Watch Technology (EWT) laboratory, a research department entirely devoted to pushing the limits of hand-crafted finishing.

The Balancier QM thus becomes the first concrete expression of this new step in the history of Greubel Forsey.

A compact watch, yet of fascinating complexity

Housed in an elegant 39.60 mm white gold case, the Balancier QM displays the hours, the minutes, the small seconds as well as a mysterious 72 hours power reserve.

Powered by a manually wound mechanical movement made up of 298 components, it favors a particularly spectacular three-dimensional architecture. The movement’s different levels create a remarkable sense of depth, made even more striking by the two domed sapphire crystals that offer a completely unobstructed view of the mechanics.

The escapement occupies the lower level while the eye is naturally drawn to the small seconds, the barrel and then the flame-blued steel hands. Beneath the hour ring, the power reserve indication appears discreetly, perfectly integrated into the whole.

Seven finishes for a single component

The Qualité Musée philosophy is revealed in the smallest details.

The balance bridge, though tiny, concentrates on its own seven different finishing techniques carried out entirely by hand: rounded polishing (poli bercé), black polishing (poli bloqué), circular graining (perlage), circular finishing (cerclage), straight graining (traits tirés), polished bevels (anglages polis) and wide chamfers reaching 0.40 mm.

This pursuit of perfection is found across all 298 components of the movement.

Even the elements that become invisible once the watch is assembled receive exactly the same level of finishing as the exposed parts. A particularly rare approach that expresses the manufacture’s philosophy: a watch must not only impress when you look at it, it must be flawless down to what no one will ever see.

A balance wheel at the heart of the innovations

The Balancier QM does not merely excel through its finishing.

Its regulating organ benefits from significant technical developments, notably a double-level escape wheel whose every face is beveled and polished with the same care, as well as convex pallets designed to optimize the behavior of light on the rubies.

The 12.60 mm variable-inertia balance wheel receives six gold adjustment screws and naturally becomes the centerpiece of the movement.

These technical advances will not remain exclusive to this edition. Greubel Forsey already announces their gradual integration into the rest of the collection.

A hairspring made entirely in-house

Among the most remarkable elements is the hairspring, now produced entirely within the Greubel Forsey workshops.

This project, launched back in 2012, represents one of the most ambitious industrial undertakings in independent haute horlogerie. The manufacture develops its own alloy, draws the wire through natural diamond dies before rolling it down to tolerances of only a few microns.

The hairspring is then coiled by hand and stabilized in a high-precision vacuum furnace.

After the Hand Made 1 and Hand Made 2, the Balancier QM marks the beginning of the gradual roll-out of this in-house production across future Greubel Forsey timepieces.

A mechanical spectacle visible on both sides

The back of the watch reveals an equally impressive spectacle.

The winding system showcases wheels with hand-polished openings, beveled and polished teeth, as well as click springs featuring perfectly executed black polishing.

Here again, no compromise is accepted. Each part receives exactly the same treatment, whether immediately visible or completely hidden beneath the movement.

The only mention of “Qualité Musée” is in fact deliberately concealed, engraved on an interior plate. A discreet detail that perfectly illustrates the manufacture’s state of mind.

A highly exclusive edition

The Greubel Forsey Balancier QM will be produced in only 33 examples.

More than a limited edition, it symbolizes a major turning point in the manufacture’s history. This new philosophy will guide the coming creations, already announced with ever more compact cases, notably a 37.9 mm Nano Foudroyante as well as several new movements expected between 2026 and 2027.

By finally giving a name to the standard that has driven each of its creations for more than twenty years, Greubel Forsey does not simply present a new watch. The house affirms a deep conviction: true haute horlogerie is not measured by the number of pieces produced, but by the excellence of every single one.

With the Balancier QM, this vision now has a name. Qualité Musée.
