Greubel Forsey’s Double Tourbillon 30° Technique (DT30T) has won the 2011 International Chronometry Competition held at the Museum of Horology in Le Locle, Switzerland. The DT30T, featuring a 60-second tourbillon cage inclined at 30° rotating inside a second four-minute tourbillon cage, scored 915 points out of a possible 1,000 to claim first place both in the tourbillon category and the overall competition.
This latest triumph completes a hat-trick of major prizes for Greubel Forsey: the Prix Gaïa for “Entrepreneurship” in 2009, the Aiguille d’Or for best overall watch at the Grand Prix d’Horlogerie de Genève in 2010, and now the International Chronometry Competition crown.
Eighteen pieces were entered into the precision competition in three categories: “Tourbillon Category‟, “Classic Category‟ for standard escapements and a “School Category” for students at select watchmaking schools.
The fully-cased timepieces were first subjected to 15 days of tests at the Observatory in Besançon, France, then 15 days of tests at the COSC laboratory in Bienne, Switzerland, followed by exposure to a magnetic field and repeated shocks before undergoing yet another 15 days of tests at the COSC laboratory in Bienne.
The DT30T entered into this year’s competition is a standard timepiece from the brand’s regular line.
Company co-founder Stephen Forsey said: “We are delighted to have achieved the fine distinction of creating the most accurate timepiece as evaluated at this year’s International Chronometry Competition. I’d like to thank everyone at Greubel Forsey for their extremely hard work and for making this achievement possible.”
Company co-founder Robert Greubel added: “This is a joyous moment for Greubel Forsey. All of our complications are conceived, created and tested with the aim of improving timekeeping precision. Entering for the second time is not only a measure of our support for the competition, but also serves as an independent validation of our inventions. Collectors can now choose a Greubel Forsey timepiece with the certain knowledge that they are acquiring the best of reliability and accuracy.”
