whatsappDescription
The Double Tourbillon 30° Technique is an open worked version of the first watch Greubel Forsey ever launched; the Double Tourbillion 30°. Hour indices on a sapphire disc appear to float inside the case and every aspect of the movement seems to jump out at you. The Technique Black brings a welcomed weight reduction with the ADLC coated titanium case while still highlighting the movement on the inside.
This patented system helped Greubel Forsey win the 2011 Concours de Chronométrie, a significant accomplishment as the most accurate watch entered in the competition. It features two tourbillon cages; one rotating every four minutes, and an interior cage containing the balance wheel and spring. The smaller tourbillon cage is inclined at 30° relative to the first cage and completes its revolution once per minute. The different rotational speeds combined with the inclination improves timekeeping by averaging out positional errors due to gravity.
