    • Catalogue Essay

      In 2004, Greubel Forsey released its first mechanical marvel, the Double Tourbillon 30° featuring a patented 30° inclined tourbillon carriage, which revolutionized high-end watchmaking. The tourbillon is set within another, and effectively compensates for gravity-related errors.

      The Invention Piece 1 is a homage to the original masterpiece and took 4 years to develop.

      The double tourbillon which is inclined at 30° is placed at the centre of a semi-circular hour and minute display. Time is indicated via two triangular indicators – a red one for the hours and a blue one for the minutes.

      Watching the different rotation of the different elements is mesmerizing, whereas the outer tourbillon cage takes four minutes to perform a complete rotation and the inner cage just 60 seconds, the double hands turn in 24 hours for the hours display and two hours for minutes.

      The case back features a very original engraving which sets Greubel Forsey’s philosophy on the watch and their watchmaking.

      The Invention Piece 1 was made in 11 pieces in platinum, 11 pieces in pink gold and 11 pieces in white gold like the present example in overall excellent condition.

      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.

      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.

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.
