  • Catalogue Essay

    With an asymmetric case design, a dial featuring three different GMT/world time indications, and an inclined tourbillon, this timepiece is a watchmaking tour-de-force both from an aesthetic and a technical point of view.

    The dial itself is simply mesmerizing. The main time indication is relegated to a subdial at 12 o’clock, flanked to the right by the fan-shaped power reserve indication and another subdial for the constant seconds. On the left side of the main dial, one finds the main GMT indication, controlled by the pusher in the band. The lower part of the dial is dedicated to the main features of the watch. On the left, a globe surrounded by a 24 hours ring gives a visual impression of the current time through the planet. A window on the band allows the beholder to gaze at the southern hemisphere.

    On the right one can admire a 25 seconds tourbillon featuring a 24 degree inclination. This particularly complex configuration required enormous efforts in research and development (focused for example on the teeth geometry for the inclined escapement, or on the energy management in a 24 seconds tourbillon - a much faster rate than the usual 60 seconds) but allows for improved accuracy and a more striking visual effect.

    Turning the watch around to its case back, an additional world-time indication is prominently displayed by a wheel with 24 cities featuring an inner “summer time” ring and an outer “winter-time” ring - this being a less artistic but more readable rendering of the world time complication compared to the rotating globe.

    The present piece is number 62 of a limited edition of 100 pieces.

    The present limited edition white gold example is offered in very attractive condition and complete of all of its accessory - a true delight for the connoisseur of high-end watchmaking.

    Please note that Greubel Forsey generously offers a complementary servicing of the watch followed by a 2 year warranty to the winning bidder within a period of 6 months after the sale.

  • Artist Biography

    Greubel Forsey

    Swiss • 2004

    With the introduction of the Double Tourbillon 30 at Basel World in 2004, Robert Greubel and Stephen Forsey became major players in the world of haute horology and independent watchmaking. Their firm concentrates on high-end complicated movements with precision timekeeping and the highest quality hand finishing. They achieve this with movements featuring multiple tourbillons and inclined balance wheels — tourbillons designed for wristwatches. Forsey joined Greubel's team at Renaud & Papi SA, a high-complication specialist now part of Audemars Piguet. The team participated with Harry Winston and their Opus 6 project. In the span of 12 years, the firm has become highly sought-after by collectors for their innovative timekeeping and industrial design.
