First released in 2004, the present Double Tourbillon 30° by Greubel Forsey exemplifies many of the watchmaker's finest qualities. It takes more than four years to develop and validate this exceptional timepiece. The watch features a patented 30° inclined tourbillon carriage that revolutionized the market. The tourbillon is set within another tourbillon which permanently compensates the rate of gravity related errors. The exterior tourbillon is inclined at 30° and rotates in 60 seconds and the inner tourbillon carriage rotates every four minutes. The 30° inclination ensures a better chronometric performance while maintaining an acceptable depth to the watch.

This ground-breaking invention is prominently displayed through a glazed aperture on the silvered dial.

Accompanied with original certificate and fitted presentation box, the present watch is very sought after today.
