Greubel Forsey’s newest masterpiece is the Quantième Perpétuel (QP) à Équation now available with a multi-level silvered gold dial. A stunning creation from the buzz worthy brand. We were given exclusive access to the new Millésimé Édition and can represent that the piece is justas gorgeous as the photos depict.

For those unaware of the QP à Équation’s prowess, allow me to give you a brief introduction. The watch encompasses what Greubel Forsey calls their “Mechanical Computer”. This Mechanical Computer acts as an astronomical clock. Made up of 25-parts, the mechanism moves it’s various wheels and disks to provide the equation of time on the dial and movement side.

The new dial

On this new edition, Greubel Forsey introduced a multi-level silvered gold dial. The new dial treatment is deeply stunning as you can see by the photos. The dial also refracts light in such a way that causes a tonal shift under different conditions.

Beyond telling the time, the dial displays the day, date, month, leap years, 24hr day/night indicator, and power reserve. The piece certainly packs a lot into the 43.5mm case, but still remains very balanced. Nothing about feels out of place.

Tourbillon 24 Secondes

I’ve been captivated by Greubel Forsey’s tourbillons for years. I had the opportunity to see the hand-finishing done in-house in La Chaux de-fonds and it was spectacular. I was mesmerized by the attention to detail Stephen Forsey and his team put into each component no matter how small.

For the QP à Équation, the brand utilized tourbillon oscillator set at 25° which allows them to overcome accuracy issues at nearly all positions. The tourbillon is clearly visible at 10 o’clock on the dial and movement side. It’s really a sight to behold.
