Greubel Forsey names the thing it has long practiced. The Balancier QM is the first watch to carry the Qualite Musee standard – a declaration that every single part must stand as a work of art. Hand-wound, with hours, minutes, small seconds and a discreet sector power-reserve, it arrives in a 39.60 mm white gold case, limited to 33 pieces.
The standard is not a plaque but a method. One steel balance bridge alone combines seven finishes: barrel polishing over a domed profile, flat black polish at the jewel, spotting, circular graining in the recess, hand-polished flanks along the contour, straight graining elsewhere, and broad hand-polished bevels at 0.40 mm. Now multiply that mindset by 298 components.
The escapement is finished where others rarely look. A bi-level escape wheel is bevelled and polished on both faces, while convex pallet-jewels guide light along their length. At the center sits an in-house variable-inertia balance of 12.60 mm with six gold mean-time screws. The new escape-wheel geometry and convex pallets will roll out across the collection, as will those generous bevels and polished flanks where they make sense.
The hairspring is made in-house from raw alloy – drawn through natural-diamond dies, rolled, hand-coiled, heat-set. Greubel Forsey proved it on Hand Made 1 in 2019 and Hand Made 2 in 2025. With Balancier QM, full in-house hairsprings begin to extend to the entire line. Not for vanity, they say, but for control.
Architecture serves finishing. Within 39.60 mm, the movement is built in layers: the escapement set deep, small seconds on a higher plane, the barrel revealed, flame-blued hands above, and a chapter ring under which the power-reserve hand slips to show a 72-hour chronometric reserve. Two high-domed sapphires give the scene air and light.
Flip it over and the winding system takes a bow: wheels with concave hand-polished sinks and polished teeth, hand matt lapped surfaces, clicks and springs flat black polished with unbroken bevels, and gold plates finished to the same standard. Even the hidden steel parts are finished like the visible ones. If you finish only what shows, you admit the watch is for show. This one is not. A small secret plate inside carries the inscription Qualite Musee – nowhere on the dial.
This debut also points forward. A new Nano Foudroyante at 37.9 mm lands later this year, a new movement in a 39.5 mm convex case before end-2026, and in 2027 both a new invention at 39.5 mm and another movement at 38.5 mm. Production may tighten as standards rise. A next EWT project explores a gear train in gold. Less noise, more intent – the atelier as museum, but one that runs on the wrist.
