The Technique is testament to Greubel Forsey’s philosophy of technical visibility. The eye is drawn from one gear to the next, enabling careful observation of each separate element.
At the heart of the timepiece is the Double Tourbillon 30° mechanism; however, additional technical developments include four fast-rotating co-axial barrels, which are coupled to a visible spherical differential driving the power reserve indicator.
Hours are displayed on a transparent sapphire crystal ring fitted inside the bezel to ensure full visual access to the astonishingly three-dimensional depth of the mechanism. The words of Robert Greubel and Stephen Forsey in bas relief text, convey their total dedication to their art.
