Greubel Forsey’s Double Tourbillon 30° was introduced in 2004 following four years of research and development. The timepiece featured a patented double tourbillon system with an exterior tourbillon inclined at 30° degrees and rotating every 60 seconds, while the inner tourbillon carriage rotated every four minutes. This complication compensated for the rate of gravity-induced errors in both the escapement and oscillator.

The present watch is the new generation model in Greubel Forsey’s Art of Invention and an expression of their ideas and spirit, namely that of transparency. The sapphire crystal and open movement allows for the individual components to be visualized. The quadruple barrel is seen rotating as the movement is wound, and allows for a 120- hour running time compared to the earlier 72-hours. The constant seconds are positioned at the 9 o’clock and highlighted by a red indicator hand. The double tourbillon carriage is prominently placed at the 6. The watch contrasts between the 5N red gold case and titanium plates with black Amorphous Diamond Like Carbon (ADLC) coating.

Produced in a limited edition of 22 timepieces, the Double Tourbillon 30° was manufactured in both 5N Red gold and titanium. The present example is in excellent overall condition and was most likely only worn a handful of times. Offered with its Certificate of Authenticity, this is a rare opportunity to own a new generation work of art.
