Success for the Double Tourbillon 30° Technique (DT30T) in 5N red gold by Greubel Forsey that won the 2011 International Chronometry Competition held on 21 October at the Watchmaking Museum in Le Locle, Switzerland. The DT30T, with its double tourbillon, the inner one inclined at 30° that rotates in 60 seconds and the outer one that makes one rotation in 4 minutes, scored 915 points out of a maximum of 1,000, taking first place in both the tourbillon category and all the categories competing. The watches, with their encased movements, are first subjected to 15 days of testing at the Besançon Observatory in France, followed by another 15 days of testing at the COSC laboratory in Bienne, Switzerland. To complete the tests, the timepieces are also exposed to magnetic fields and repeated shocks, before undergoing another 15 days at the COSC laboratory in Bienne. For Greubel Forsey, this is the second edition he has taken part in this year. In fact, he had already taken part in the Chronometry Competition in 2009 with the Quadruple Tourbillon. "We are delighted to have achieved our goal of creating the most accurate watch as judged by this year's Chronometry Competition," said Stephen Forsey, co-founder of the brand. "I would like to thank everyone at Greubel Forsey who worked so hard to make this achievement possible." Robert Greubel, co-founder of the Maison, added: "This is a happy moment for Greubel Forsey. All our complications are created and tested with the aim of improving precision. Entering the competition for the second time reaffirms our support for the competition, as well as the independent validation of our inventions. Collectors will now be able to choose a Greubel Forsey with the knowledge that they are buying the best in reliability and precision."
