Catalogue Essay
The Double Tourbillon 30° Technique is, without a doubt, one of the most breathtaking wristwatches from Greubel Forsey. Described by Stephen Forsey as “a theatre, in which the eye is drawn to the highly finished movement,” this stunning piece in white gold has an impressive diameter of 47.5 mm. It’s an openworked marvel, building on the original Double Tourbillon 30° Contemporaine launched back in 2005. To achieve its captivating three-dimensional look, the team crafted an entirely new movement influenced by everything from industrial designs to childhood Meccano sets. The result? A watch that exudes depth and displays its jaw-dropping intricate inner workings.

Introduced between 2009 and 2022, this exquisite timepiece is limited to just 188 pieces, each crafted from luxurious materials like white gold, pink gold, platinum, sapphire, titanium, and ceramic. Greubel Forsey’s mission with the Double Tourbillon 30° Technique was crystal clear: they wanted to create a timepiece that allows the wearer to fully appreciate the magic happening inside. And they nailed it! The hand-finishing is simply extraordinary. This watch features two tourbillon cages, with the outer one spinning every four minutes, while the inner cage—tilted at 30 degrees—makes its own revolution in just sixty seconds. This clever design boosts timekeeping accuracy by averaging out any pesky positional errors caused by gravity.

You might wonder: does a tourbillon really make a watch more accurate? Well, this beauty proved it does. In 2011, it clinched the Concours International de Chronométrie with an astonishing score of 915 points out of 1000, the highest ever recorded in that competition.

Owning the Double Tourbillon 30° Technique is like having a piece of horological art that’s both rare and exciting. It’s a culmination of the expertise and craftsmanship of two of the most talented watchmakers alive today.

The Greubel Forsey quality never comprises, its finishing is truly unbelievable and completely hand-finished with utmost attention to details. The caseband is hand finished with micro texts, main plates are frosted with polished bevelling and counter sinks. The central post that supports the hour and minute hands takes an entire week to machine, not including the extensive finishing work that follows. This meticulous hand-finishing process is incredibly time-consuming.

Celebrated as Greubel Forsey's first fundamental invention, numbered 44 and according to our research the second white gold example to ever surface publicly in the market, this watch represents a major leap forward in watchmaking, taking over four years of dedicated research to perfect. Complete with its certificate and impressive wooden presentation display case, the Double Tourbillon 30° Technique is a stunning blend of tradition and innovation, pushing the boundaries of what a wristwatch can be!
