The Double Tourbillon Technique is an entirely original and innovative interpretation of Greubel Forsey’s first fundamental invention, the Double Tourbillon 30°. It is a timepiece with a boldly assertive character and a totally unique architecture.
With the Double Tourbillon Technique, Robert Greubel and Stephen Forsey have created a truly stunning timepiece that is faithful to their philosophy of technical visibility. Each and every element of the mechanism is enhanced and displayed without overshadowing others.
At the heart of the timepiece is the Double Tourbillon 30° mechanism ; however, to perpetuate the art of horology and contribute to its 21st century development, several additional technical elements have been added, including four fast- rotating co-axial barrels guaranteeing 120 hours of autonomy.
Admirers can even enjoy the sight of the barrels rotating while winding and unwinding. Coupled to these barrels is the visible spherical differential that drives the power reserve indicator. The hours are displayed on a transparent sapphire crystal ring fitted inside the inner circumference of the bezel to ensure full visual access to the astonishingly three-dimensional depth of the mechanism. Transparency is also reflected in the luminous openworked signature Greubel Forsey hands and both the power reserve indicator at 3 o’clock and sub-seconds dial at 9 o’clock are strikingly enhanced by their red triangular pointers.
The Double Tourbillon Technique is a case study in precision mechanical watchmaking with the sapphire crystal acting as a portal through which to observe the mesmerising workings of the intricately interlocking parts. The eye is naturally drawn from one gear to the next, enabling careful observation of each separate element.
The DT30T, featuring a 60-second tourbillon cage inclined at 30° rotating inside a second four-minute tourbillon cage, scored 915 points from a possible 1,000 to claim first place both in the tourbillon category and the overall competition.
This watch completes a remarkable hat-trick of major prizes for Greubel Forsey. They now have the distinction of being the only brand to have won the Prix Gaïa for “Entrepreneurship” (2009); the Aiguille d'Or – best overall watch – at the Grand Prix d'Horlogerie de Genève (2010), and now the International Chronometry Competition.
The fully-cased timepieces are first subjected to 15 days of tests at the Observatory in Besançon, France, then 15 days tests at the COSC laboratory in Bienne, Switzerland, followed by exposure to a magnetic field and subjected to repeated shocks before undergoing yet another 15 days tests at COSC laboratory in Bienne.
