Greubel Forsey Tourbillon 24 Secondes Vision Platinum – Chocolate, Blue and Anthracite Black dials

In 2016, Greubel Forsey extended the Tourbillon 24 Secondes Vision range with a “Salmon” dial edition. Now, the brand presents three new dial versions: “Chocolate”, “Blue” and “Anthracite Black”.

One timepiece with four different faces: it is a unique situation as, usually, Greubel Forsey only creates one edition of each of its platinum timepieces. These versions follow the success of the Tourbillon 24 Secondes Vision, which was awarded the Aiguille d’Or 2015 by the jury of the Grand Prix d’Horlogerie de Genève.

During the creation of the Tourbillon 24 Secondes Vision, Robert Greubel and Stephen Forsey were confronted with a major challenge: how to house the mechanism of the Tourbillon 24 Secondes without sacrificing the timepiece’s pure, elegant lines.

By incorporating a sapphire crystal dome into the back of the timepiece, the model’s inventor-watchmakers were able to generate the volume required to house the tourbillon mechanism, thus leading to a perfect alchemy between performance and comfort. Over and above its showcase function, the sapphire dome captures luminosity and channels it into the interior of the timepiece, allowing the tourbillon to be viewed through a veritable stream of light.

Among this timepiece’s most noteworthy features are its two curved tourbillon bridges, with their delicately hand-polished surfaces. To attain such symmetrical perfection in the finishes of the three-dimensional tourbillon bridges is no mean achievement, and indeed each bridge is discreetly signed by the artisan decorator who has executed it – a good way to celebrate the excellence of such watchmaking craftsmanship.

Furthermore, in keeping with the highest standards, the movement’s 293 parts, whether visible or not, feature the very best hand finishing that can be found today.

The multi-level gold dial of this timepiece, in Chocolate, Blue or Anthracite Black, features engraved indexes (or gold appliqués depending on the version) filled with grand feu (champlevé) enamel. The hour, minute and small seconds hands are made of polished steel, which is blued in some of the versions. The countersinks are polished by hand.

The Greubel Forsey Tourbillon 24 Secondes Vision in platinum will be realised in small editions of a few pieces each year.
