Greubel Forsey: Double Tourbillon Technique/2010
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 fastrotating 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.
By virtue of its fully visible mechanism, the Double Tourbillon Technique is a showcase for Robert Greubel and Stephen Forsey’s unique blend of technical mastery coupled with superb aesthetic finishing. The timepiece reinforces their commitment to absolute quality and fine craftsmanship, also expressed in the discreet message from the inventor watchmakers engraved around the case band.
