Good To Know:

- Double Tourbillon 30° Technique was made in 188 pieces only

The Double Tourbillon 30° Technique stands as one of the most extraordinary wristwatches produced by Greubel Forsey. This stunning pink gold piece boasts an impressive diameter of 47.5 mm and features an openworked design that evolves from the original Double Tourbillon 30° Contemporaine, launched in 2005.

Produced between 2009 and 2022, this exquisite timepiece is limited to just 188 pieces, each constructed from luxurious materials such as white gold, pink gold, platinum, sapphire, titanium, and ceramic. This watch includes two tourbillon cages, with the outer cage completing a rotation every four minutes, while the inner cage, tilted at 30 degrees, makes a full revolution every sixty seconds. In 2011, it achieved an impressive score of 915 points out of 1000 at the Concours International de Chronométrie—the highest score ever recorded in the competition.

Recognized as Greubel Forsey's first fundamental invention, this watch, numbered 23, represents a significant advance in watchmaking, requiring over four years of dedicated research to perfect. This particular piece was serviced at Greubel Forsey in 2025, with its movement being overhauled.

Greubel Forsey

Swiss | 2004

With the introduction of the Double Tourbillon 30 at Basel World in 2004, Robert Greubel and Stephen Forsey became major players in the world of haute horology and independent watchmaking. Their firm concentrates on high-end complicated movements with precision timekeeping and the highest quality hand finishing. They achieve this with movements featuring multiple tourbillons and inclined balance wheels — tourbillons designed for wristwatches. Forsey joined Greubel's team at Renaud & Papi SA, a high-complication specialist now part of Audemars Piguet. The team participated with Harry Winston and their Opus 6 project. In the span of 12 years, the firm has become highly sought-after by collectors for their innovative timekeeping and industrial design.
