The DT30T, featuring a 60-second tourbillon cage inclined at 30° rotating inside a second four-minute tourbillon cage, scored 915 points from a possible 1,000 to claim first place both in the tourbillon category and the overall competition.

This latest accolade completes a remarkable hat-trick of major prizes for Greubel Forsey. They now have the distinction of being the only brand to have won the Prix Gaïa for “Entrepreneurship” (2009); the Aiguille d'Or – best overall watch – at the Grand Prix d'Horlogerie de Genève (2010), and now the International Chronometry Competition.

Eighteen pieces were entered into the precision competition in three categories: ‘Tourbillon Category', ‘Classic Category' for standard escapements and a ‘School Category‘ for the watchmakers of tomorrow.

This year marked the second edition of the International Chronometry Competition since its introduction in 2009 when Greubel Forsey entered the Quadruple Tourbillon.

The fully-cased timepieces are first subjected to 15 days of tests at the Observatory in Besançon, France, then 15 days tests at the COSC laboratory in Bienne, Switzerland, followed by exposure to a magnetic field and subjected to repeated shocks before undergoing yet another 15 days tests at COSC laboratory in Bienne.

The Greubel Forsey Double Tourbillon 30° Technique DT30T in 5N gold entered into this year's competition is a standard timepiece fully representative of those created for collectors.

Company co-founder Stephen Forsey believes that winning the International Chronometry Competition is fine recognition for Greubel Forsey's constant quest for innovation and perfection, and that superlative precision can now be officially added to the qualities of excellent finishing and the innovative horological architecture for which Greubel Forsey timepieces have become renowned.

“We are delighted to have achieved the fine distinction of creating the most accurate timepiece as evaluated at this year's International Chronometry Competition,” said Stephen Forsey. “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.”
