DESCRIPTION

  • A Journey into the heart of the mechanism 

    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. 

    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. 

    A true work of technical art 

    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. 

    A powerful personal message 

    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. 

    These highly personal words convey Robert Greubel and Stephen Forsey’s total dedication to their art and their contribution to horological advancement through fundamental research, the sophisticated architecture of their movements and their relentess pursuit of optimal timekeeping.
