Greubel Forsey QP à Equations and "Mechanical Computers" Greubel Forsey's seventh “invention”, the Greubel Forsey QP à Equation luxury Replica Watch site, was unveiled to the watch intellectual community today at the 2015 SIHH. It is a rich collection of ultra-complex mechanical watches. It should be heaven for everyone, as well as the high-end retailers who supply these watches. Geneva.
The Greubel Forsey QP à Equation is the first timepiece to incorporate a new mechanism into its movement, which Greubel Forsey calls a “Computeur Mécanique” (mechanical computer). The device, for which the brand has filed multiple patent applications, is a sub-assembly of 25 parts, inspired in part by the system used in large astronomical clocks since the late 15th century to manage information that determines certain key dates. Ecclesiastical calendar related to astronomical data.
The mechanical "brain" at the heart of the invention consists essentially of rotating coaxial coding elements, the arrangement of which is complemented by a system of programmed movable parts. Depending on its geometry and rotational speed, each element generates its own instructions in a cyclic, pre-programmed manner. In this way, a mechanical computer cleverly miniaturized and integrated into the watch movement is able to automatically display all of the watch's indications, each generated by its own coaxial coding element. In the case of QP à equations, these functions include all the functions of a perpetual calendar as well as the equations of time: seasons, equinoxes, solstices, equations of time as well as date, day of the week, month and four-digit year. (For example, one of the coding elements is specifically programmed to account for and compensate for leap year differences.) replica watches luxury
Despite its extremely complex mechanism, Greubel Forsey's seventh invention is surprisingly simple to operate. All eight of the watch's indications are controlled by a single selector set in the movement's winding crown; the wearer simply turns the crown in either direction to adjust without damaging the mechanism.
Greubel Forsey is a watch manufacturer not known for doing things simply – after all, its first invention was the tilting double tourbillon movement – and as always, with its first use of a mechanical computer , which chooses to focus on the equation of time is one of the rarest (and, frankly, probably the least known) astronomical complications that is directly related to the perpetual calendar.
Simply put, time difference measures the difference between "true" solar time and the more traditional "civil" or mean time, which is fixed at 24 hours per day throughout the year. The length of a day in solar time varies depending on the Earth's position in its elliptical orbit around the Sun. For example, the November solar day is about 16 minutes longer than the civil day, but the February solar day is about 14 minutes shorter than the civil day. The unique time equation display on the Greubel Forsey QPà Equation dial uses two sapphire crystal discs, driven by a mechanical computer, that rotate independently to show the changing time differences throughout the year. The equinoxes, solstices, and four seasons are also displayed in the equation of time indicator located on the back of the movement.
