SIHH 2015: Greubel Forsey novelties including the GMT with 5N movement and the final execution of the QP à Equation

Greubel Forsey is somewhat special in the business, for several reasons. Their creations of time-telling bits of art are essentially flawless, complicated, extraordinary, costly. Nothing here is rational. What difference does it make? Simply take a glance at these twofold or quadruple tourbillons, at the completion of the movements, at the globe of the GMT.

SIHH 2015: Greubel Forsey novelties including the GMT with 5N movement and the final execution of the QP à Equation

Greubel Forsey is somewhat special in the business, for several reasons. Their creations of time-telling bits of art are essentially flawless, complicated, extraordinary, costly. Nothing here is rational. What difference does it make? Simply take a glance at these twofold or quadruple tourbillons, at the completion of the movements, at the globe of the GMT. It’s far to be classical horology. Today we’re presenting the SIHH 2015 curiosities, including a new release of the GMT, with all its technical marvels against a beautiful 5N gold movement and the final execution of the QP à Equation.


GMT with 5N Movement

The first SIHH 2015 oddity introduced by Greubel Forsey is another version of a notable watch, the GMT. We’ve seen as of late this watch in a full Black ADLC release , also part of the 2015 assortment. Presently, it comes in a 950 Platinum case, contrasting with the warm and brilliant shade of the 5N Gold – also known as pink gold. This tone can also be found on the back of the Greubel Forsey GMT – which reveals the world-clock indication, with 24 urban areas. On the front, all the technical or functional components are uncovered, separately to keep a decent readability. It shows at the very least a main hour/minute dial, a small second (at 3), a force save indicator at 4, the 24-second tourbillon slanted at 25 degrees, the rotating globe with universal time and another time region at 10.

More details about this watch in our past articles here, when originally presented , and here, when introduced in platinum . The Greubel Forsey GMT 5N Movement is a restricted version of 22-pieces.


 QP à Equation

This watch isn’t different to us. We’ve seen it last year. In any case, it was just a model with incomplete movement and some approximate finishings. Here is the final and authoritative execution of the Greubel Forsey QP à Equation – a perpetual calendar with equation of time, a la Greubel, meaning it’s not a simple QP. In the event that you look carefully, all the indications of the QP are located in a small area – at 4 – displayed by 3 apertures – one for the afternoon, one for the date and one for the month. Profoundly clear, this display can be viewed as straightforward, however in fact, it is Greubel Forsey’s seventh innovation, the ‘Computeur Mecanique’.

This mechanical brain is a sub-assembly of 25 parts, mainly comprising of rotating coaxial coded components in an arrangement complemented by an arrangement of programmed movable areas. Contingent upon its math and speed of rotation, each component generates its own indication in a cyclical, preprogrammed way. In the setting of the QP à Equation, the Mechanical Computer is programmed to automatically display all the indications of the perpetual calendar through to the equation of time: the seasons, the equinoxes, the solstices, the equation of time, and the date, day, month and the four-digit year.

This equation of time is displayed in an original and straightforward way by two sapphire crystal circles driven by the Mechanical Computer which rotates them freely to show the time contrast as it changes consistently. The equinoxes and solstices, similar to the four seasons, are displayed in a graceful choreography while as yet giving a very exact indication.

The front and case of the Greubel Forsey QP remains roused by the DNA of the brand: complex display with separated indications, inclined tourbillon, great movement with massive inclined angles and iced finish. Another masterpiece that shows that the two originators, Robert Greubel and Stephen Forsey, have some really creative personalities and astounding technical solutions.
