To mark the occasion of the Spring Equinox, Greubel Forsey, the Swiss watchmaking company specializing in complicated, high-end timepieces, revealed Greubel Forsey QP à Équation in its 5N red gold edition with a multi-level chocolate-colored gold dial.
Greubel Forsey QP à Équation with Mechanical Computer.
The watch offers a bouquet of ultra complications: Bidirectional perpetual calendar, day, date, month, calendar year, leap year, day/night , equation of time with month, season, solstice and equinox, function selector, Tourbillon 24 Secondes, hours and minutes, small seconds, power reserve.
By reinventing the prestigious perpetual Calendar (QP), with the QP à Équation, Greubel Forsey demonstrates through their art of invention that the history of mechanical watchmaking remains in a perpetual state of evolution.
At the heart of the QP à Équation lies Greubel Forsey’s seventh invention, the Mechanical Computer, an entirely integrated 25-part component that brings a totally new interpretation to some of the calendar functions incorporated in age-old astronomical clocks. It is composed of a set of coding wheels superimposed in a coaxial manner, along with removable fingers programmed by this ingenious system.
This reinvention of the perpetual calendar integrates the Equation of Time into the perpetual calendar, as well as bringing practical new functions and indications that improve clarity. The priority was to simplify a complete perpetual calendar display and yet make it much easier to set by simply using the bi-directional crown. Despite the numerous indications and functions, Greubel Forsey’s mechanical computer is as easy to set as a simple date feature.
The crown pusher function selector allows to select either the hours minutes adjustment or the perpetual calendar bi-directional rapid correction, which enables to modify day of the week, large date, years and equation of time. (1 crown turn corresponds to 3 days).
This luxury timepiece also indicates the 24 hours (day/night) with a fully integrated security for calendar rapid correction in the red zone (between 10.30 pm and 1.00 am). The Hour/Minute correction works at all times.
Just a glance at the calendar display reveals the three in-line windows that clearly indicate the day, the date and the month. The large date makes the calendar extremely legible.
