This reinvention of the perpetual calendar integrates the Equation of Time into the perpetual calendar, as well as practical new functions and indications that improve clarity. The priority was to simplify the complete displays and make it easier to set the perpetual calendar by using the bi-directional winding crown. Despite the complete indications and functions, Greubel Forsey's mechanical computer with Equation of Time is as easy to set as a simple date feature.

Greubel Forsey Watch Brand History

One common denominator of all Greubel Forsey's inventions, besides their sublime beauty, is that they all reliably improve timekeeping precision. The 'Double Tourbillon 30°', Greubel Forsey's first invention, features two tourbillons, one rotating inside the other. In the second invention, four asynchronous tourbillons independently contribute to the extremely high accuracy of the 'Quadruple Tourbillon The third fundamental invention, the 'Tourbillon 24 Secondes Incliné, masters positional errors using a single ultra-light inclined tourbillon cage rotating with high angular velocity.

Robert Greubel and Stephen Forsey have been working together for nearly 20 years in a relationship founded on their shared technical creativity and quest for perfection. In 1999 they began working on a new generation of tourbillon specifically designed to improve the timekeeping of the mechanical watch. Four years later they unveiled "Greubel Forsey" and stunned horological aficionados with their innovative Double Tourbillon 30°, a timepiece clearly demonstrating their twin goals of innovation and excellence. Greubel Forsey's finished inventions are the result of years of stringent development and exhaustive testing.
