Introducing Greubel Forsey Unveils the QP Balancier

Greubel Forsey has long been recognized for challenging conventions in high horology, building its reputation on complex, innovative, and impeccably finished timepieces. The brand initially focused on the tourbillon before expanding into other complications. Among these, the perpetual calendar is often regarded as one of watchmaking’s crown jewels, yet it has traditionally been plagued by fragility, excessive complexity, and cumbersome resets. Greubel Forsey’s answer came in 2015 with the Quantième Perpétuel à Équation, which introduced the patented Mechanical Computer, a 25-part mechanism that redefined the complication by making it intuitive and reliable. With its latest creation, the QP Balancier, the maison distills that breakthrough into its purest expression, combining ease of use with the uncompromising standards of chronometry and craftsmanship that define the brand.

The watch is housed in a white gold case measuring 45.1 mm in diameter and 14.75 mm in thickness. Its design reflects a cleaner aesthetic compared to earlier Greubel Forsey perpetual calendars, eliminating bulky protrusions while preserving a strong architectural presence uniting 12 functions and indications in a single crown. A domed sapphire crystal protects the dial, while a transparent sapphire back reveals the intricacies of the movement, including the year display discs and the patented Mechanical Computer. Water resistance is rated at 30 metres.

The dial, crafted in multi-level gold with an anthracite finish, is arranged for maximum legibility. Day, large date, and month are displayed linearly, complemented by leap year and day/night indicators. Small seconds and a 24-hour display appear on overlapping discs, the latter featuring a red safety zone that signals when adjustments are disabled. A power reserve display and a function selector, which toggles between time and calendar setting, complete the ensemble. Polished steel hands coated with Super-LumiNova ensure visibility in all conditions.

Inside, the manually wound calibre features a 12.6 mm balance wheel, free-sprung and inclined at 30° to enhance chronometric performance by minimizing positional errors. Beating at 21,600 vph (3 Hz), it is powered by two coaxial fast-rotating barrels that provide a 72-hour power reserve. The perpetual calendar mechanism, operated entirely via the crown, allows bi-directional adjustments at any time of day. It is mechanically programmed until the year 2100, requiring only a minor correction thereafter.

The QP Balancier is paired with a hand-sewn black textured rubber strap secured by a white gold folding clasp engraved with the Greubel Forsey logo. Limited to just 22 pieces, its price is available upon request.
