GREUBEL FORSEY Tourbillon 24 Secondes Asymmetrical Platinum Anthracite Gold Dial

With the inclined Tourbillon 24 Secondes, Greubel Forsey capitalizes upon the speed of rotation and the inclination of the regulator to harness the influence of gravity on the regulating organ. Enabling the moving parts to cover a major distance in a short space of time and to perform a complete rotation in just 24 seconds called for the implementation of innovative solutions including a specially constructed inclined gear profile.

Beschrijving:

The Tourbillon 24 Secondes in platinum is distinguished by the three-dimensionality of its dial architecture. The harmonious arrangement of the subdials creates a dynamic view of the indications as well as a majestic backdrop for the tourbillon. The 18k gold anthracite dial is comprised of interweaving curves and concentric rings complementing the new shape of the flat-polished tourbillon bridge, while sculptured Super-LumiNova filled hands offer superb legibility.
