Greubel Forsey's Double Tourbillon 30° is designed in black ADLC treated titanium and is a lighter-weight version of the watch. It features two tourbillon cages, one rotating every four minutes with an interior cage containing the balance wheel and spring. The smaller tourbillon completes its revolution once per minute. Both rotational speeds combined improve timekeeping by averaging out positional errors due to gravity.
The watch is in excellent, like-new condition. The movement is running at the time of cataloging, however, it was not tested for the accuracy of time or duration of the power reserve and may need service at the buyer's discretion. Please note that Sotheby's does not guarantee the future working of the movement.
