Greubel Forsey Quadruple Tourbillon is evidence of the company´s position as one of the foremost innovators in both design and technical advances. This timepiece is a tribute to the impossible with a total of 4 tourbillons operating the watch this is why we choose to look closer at this magnificent watch.


The movement has a diameter of 36.4 mm and a height of 9.7 mm consisting of 534 parts. The four tourbillon cages consist of 261 parts weighing as little as 2.26 grams. The spherical differential combining the tourbillons consists of 28 parts. In total there are 63 olived-domed jewels set in gold chatons in the movement. This mighty mechanic beats at 21 600 vibrations per hour allowing a power reserve of up to 50 hours. At the same time the watch wearer can view the display of hours, minutes, small seconds, power reserve and 240 seconds (4 minutes) outer-tourbillon rotation on the outer cage.

A true masterpiece indeed. However, the impressive specifications of this watch are not limited to the movement, a great deal of thought, planning and effort was made in order to match this unique movement with a case and dial.


The company expressed that “the asymmetrical form (of the case) was also an aesthetic tribute to the asynchronicity of the four tourbillons”.


We believe nothing was left to chance in this project. From the 18 karat 5N red gold case to the asymmetrical convex synthetic sapphire crystal, the lateral curved window to the three-dimensional lugs and the handmade dial this is truly a watch in a league of extraordinary details. 


The case measures 43.5 mm wide and 16.11 mm tall and is water resistant to 3 ATM / 30 meters. Fitted on a hand-sewn black alligator strap with solid gold clasp this is a tourbillon for the lucky few.
