The new QP Balancier by Greubel Forsey is the purest, most intuitive perpetual calendar ever – uniting 12 functions and indications in a single crown, with no additional pushers, no crown po- sitions to memorise, and no risk at any time. Powered by the patented Mechanical Computer and multiple security systems, it adjusts instant- ly in either direction, restarts instantly after months unwound, and stays programmed until the year 2100. Featuring our 30° inclined bal- ance wheel, it is limited to 22 timepieces in white gold.
For centuries, the perpetual calendar has been revered as one of watchmaking’s most prestig- ious complications. Yet it often came with com- promises: fragile mechanisms, cryptic interfac- es, and laborious resets whenever the watch stopped.
Greubel Forsey set out to change that. In 2015, the QP à Équation introduced the Mechanical Computer – our seventh Fundamental Invention – a 25-part mechanical brain that “knows” the Gregorian calendar rules, ensuring perfect syn- chronisation of every display.
The new QP Balancier distills this breakthrough into its most refined form. It unites 12 indications – hours, minutes, seconds, power reserve, day, date, month, leap year, day/night, 24-hour dis- play, calendar year, and the patented function selector – all operated by a single crown for ef- fortless time and calendar setting. The result is the only perpetual calendar that requires no handbook to operate.
Hidden pushers? Multiple crown positions? Forward-only adjustment? Lengthy resets? Every limitation of traditional perpetual calendars has been eliminated. The QP Balancier turns freely in both directions at any time of day, corrects instantly even after months unwound, and locks safely dur- ing the vulnerable midnight changeover, with a visible red zone for extra security. Programmed correctly until Febru- ary 28, 2100, it needs only a simple Atelier adjustment to remain accurate for another century.
Aesthetically, the QP Balancier embodies purity. Its multi-level gold dial presents day, large date, and month in a single intuitive line, flanked by leap year and day/night indicators. Every ele- ment is reduced to the essentials for instant leg- ibility and visual harmony.
The experience goes beyond sight: the quick-cor- rection mode transforms date-setting into a tac- tile pleasure, each crisp jump through the crown letting the wearer feel the mechanism come alive – a moment of connection between human and machine.
The 45.1 mm white gold case, just 14.75 mm high, houses the 12.6 mm balance wheel inclined at 30°, a high-mass, variable-inertia balance with gold mean-time screws for su- perior chronometric performance.
Each of its 612 components is hand-finished to the Atelier’s uncompromising standards – bevelled, black-polished, frosted, or straight-grained – with twin fast-rotating barrels delivering a 72-hour chronometric power reserve.
Limited to 22 timepieces in white gold, the QP Balancier is the most practical, reliable, and us- er-friendly perpetual calendar ever created – without a single compromise in chronometry, craftsmanship, or beauty.
