The Impressive Finishings of the Greubel Forsey Balancier QM

Greubel Forsey, the high-end independent brand founded in 2004, has long been associated with multi-axis tourbillons, often staged in enormous, asymmetric cases with protrusions to accommodate the mechanics and offer panoramic views. The first model to appear without a tourbillon was the Balancier, equipped with an enormous 12.6mm dial-side balance wheel. Ever evolving, the latest compact, white gold incarnation of the Balancier writes a new chapter in the trajectory of the GF09 calibre. The Balancier QM is GF’s first timepiece to bear the Qualité Musée or Museum Quality standard, a new in-house certification mandating that every single micro-component display the highest possible level of finishings to “hold up as a work of art”.

Don’t be mistaken; hand-finished components have been a permanent feature of GF’s watches since 2004. However, watches produced in the new EWT hand-finishing laboratory – from three-hand models to Grande Sonneries – will demonstrate that exceptional finishing is now as important a component of a watch as its mechanics.

To understand the lineage of the 2026 Balancier QM and its GF09 movement, we have to go back to the 2017 Balancier, the spiritual ancestor of this family. Marking the brand’s first model without a tourbillon, in its place was an enormous 12.6mm in-house balance wheel exposed in a bulge on the case flank at 8 o’clock. The forefather’s commanding 43.5mm case, with a thickness of almost 14mm, introduced other features that have defined the family: the fan-shaped power reserve and the off-centred small seconds and hour and minute counters. Two years later, GF released the Balancier Contemporain, the brand’s first watch under 40mm in a round, bulge-free white gold 36.9mm case with a height of 12.21mm and a different layout of the functions. The GF09  has also powered sportier references, housed in the brand’s 41.5mm ovoid-shaped Convexe case.

The new Balancer QM retains the 39.6mm case diameter of the 2019 reference with a thickness of 9.45mm (12.25mm including the high-domed synthetic sapphire crystals over the dial and caseback). Crafted in 18k white gold, the gleaming hand-polished bezel and lugs contrast with the hand-finished straight graining on the caseband and caseback with its white gold security screws. Equipped with eccentric hours and minutes, a small seconds sub-dial and a mysterious power reserve indicator, like many of GF’s watches, the asymmetric dial is a rich, multi-tiered three-dimensional landscape. Perforated with deep circular wells and featuring raised and suspended elements, the white gold dial’s components reveal superlative hand-finishing.

The two wells in the lowest tier are home to the gigantic variable-inertia balance wheel and the golden mainspring barrel (one of two) with its relief “Greubel Forsey” engraving. The eccentric chapter ring for the hours and minutes, indicated by flame-blued steel hands on the right side of the dial, forms the highest tier and sits above the “mysterious” 72-hour power reserve indicator. Represented by a gold arc spanning the underside of the chapter ring from 9 to 12 o’clock, the flame-blued hand anchored on the frosted mainplate vaults over the deep well of the mainspring barrel to alight on the sector. The gold power reserve sub-dial sits at 8 o’clock, on the slightly lower section of the mainplate.

To give you an idea of what the QM seal demands, the conical balance wheel bridge features seven hand-finished techniques, including black polishing, spotting, circular and straight graining, and chamfered and polished bevels. Further details attesting to the QM standard can be seen in the bi-level escape wheel, which is also bevelled and polished on both sides – even the hidden side – as well as in the convex pallet jewels (as opposed to flat).

The frosted caseback reveals parts of the winding system. The wheels are decorated with concave, hand-polished sinks with bevelled, polished teeth, and the clicks and springs are black-polished. The engraved Qualité Musée plate is deliberately hidden inside the movement. Addressing more technical features, the 298-part in-house manual-winding movement features two series-coupled fast-rotating barrels to deliver the 72-hour power reserve. Fitted with an in-house hairspring, the movement also features a stop-balance function for precision time setting. According to the brand, the QM standard will extend to future models and innovations.

The Greubel Forsey Balancier QM is paired with a hand-sewn textured rubber strap and a white gold pin buckle. It is a limited edition of 33 pieces, and the price is on request.
