Greubel Forsey Double tourbillon black titanium

 
The Technique is testament to Greubel Forsey’s philosophy of technical visibility. The eye is drawn from one gear to the next, enabling careful observation of each separate element.
At the heart of the timepiece is the Double Tourbillon 30° mechanism; however, additional technical developments include four fast-rotating co-axial barrels, which are coupled to a visible spherical differential driving the power reserve indicator.
Hours are displayed on a transparent sapphire crystal ring fitted inside the bezel to ensure full visual access to the astonishingly three-dimensional depth of the mechanism. The words of Robert Greubel and Stephen Forsey in bas relief text, convey their total dedication to their art

Technical specifications

 
Double Tourbillon Technique Black
 
The Double Tourbillon Technique Black breaks completely new ground for Greubel Forsey: It is the first black model in the Collection and the first Greubel Forsey timepiece to feature a titanium case and a rubber strap. These features endow this three‐dimensional chef d’oeuvre with more casual aesthetics than the classic gold and platinum models.
Highly polished steel bridges stand out in high‐contrast juxtaposition against the subdued black chrome of the movement plates and bridges.
The Double Tourbillon Technique Black features a unique, open‐work movement architecture in an entirely original and innovative interpretation of Greubel Forsey’s first fundamental invention, the Double Tourbillon 30°.
The Double Tourbillon Technique Black is a case study in high‐precision mechanical watchmaking.
The sapphire crystal is a portal through which to observe the mesmerising synchronised rotations of the intricate, sublimely finished, micro‐mechanics beneath. Gazing down through the multiple levels of the three‐dimensional movement, the viewer is naturally drawn from one component to the next. The open construction does not simply enable, but encourages and rewards careful observation of each separate element and their dynamic interactions.
At the heart of the Double Tourbillon Technique Black is the Double Tourbillon 30° mechanism at 6 o’clock, with the unobstructed configuration of the open movement allowing full appreciation of the ballet of the two tourbillons, one rotating inside the other.
Hours and minutes are displayed by luminous, open‐worked signature Greubel Forsey hands against a transparent sapphire crystal ring, providing full visual access and luminosity to the depths of the mechanisms below. Transparency is also manifest at 6 o’clock with a red‐tipped, four‐pointed, sapphire crystal indicator rotating in four minutes above the double tourbillon, and indicates 0‐60 seconds along a quadrant.
The three‐dimensionality of the Double Tourbillon Technique Black is apparent throughout. A visual journey across the top half of the movement takes us from the small seconds near 9 o’clock, past the four coaxial mainspring barrels and the tall jewel‐capped tripod supporting the hour and minute hands, to the power reserve indicator at 3 o’clock. Both the small seconds and power reserve indicators are balanced and strikingly enhanced by their red triangular indicators.
The four fast‐rotating co‐axial mainspring barrels provide a very generous 120 hours of autonomy.
The rotation of the barrels can be enjoyed both when winding and when unwinding. Coupled to these barrels is the visible spherical differential that drives the power reserve indicator.
Greubel Forsey are renowned for their uncompromisingly superlative finishing and decoration. The Double Tourbillon Technique Black is a kinetic showcase of this art with each and every component, visible or not, designed to highlight its form and hand finish. Plates and bridges have sharp internal angles to highlight the meticulous handcraft. Flat black‐polished steel bridges and mirror‐polished complex curves reflect light in a scintillating display, bringing unparalleled vivacity to the movement.
 
 
 
Double Tourbillon Technique Black in Detail
Open Work Movement Architecture
 
The raison d’être of the Double Tourbillon 30° Technique is its unique three‐dimensional, openwork movement architecture. Whereas a skeletonised movement takes an existing calibre and cuts away ‘superfluous’ material in only two dimensions, the movement of the Double Tourbillon 30° Technique was designed and developed from the ground up to allow unprecedented three dimensional visual access to as much of the mesmerising micro‐mechanics and mechanisms as possible. Sublimely finished components on all levels can be enjoyed from a multitude of angles thanks to the Double Tourbillon 30° Technique’s panoptic construction.
 
Double Tourbillon 30°
 
The Double Tourbillon 30° was Greubel Forsey's first Fundamental Invention presented in 2004 and features an innovative Double Tourbillon 30° mechanism with one 60‐second tourbillon inclined at 30° rotating inside another tourbillon cage rotating in four minutes. In this world‐premier construction, the double tourbillons average‐out gravity‐induced errors on the balance and spring oscillator, which improves timekeeping. This construction allows for superior chronometric performance, a minimum volume/maximum balance diameter ratio as well as enabling the beautifully finished mechanism to be fully appreciated.
 
Black Titanium Case, Lugs, Crown and Clasp
 
The central hour and minute hands are skeletonised and filled with white Super‐LumiNova that stands out against the black‐chrome finished movement beneath. The triangular hands of the small seconds and power reserve indicator are hand‐finished in red anodised aluminium. The dial of the small seconds is one piece in gold (as is the power reserve dial) with a straight‐grained centre and lapped perimeter with engraved lacquer‐filled markers. A cut away sapphire disk around the perimeter of the display features metallised hour markers. Three‐dimensional detachable lugs in titanium allow a fine finish of all surfaces of the case. The bespoke Greubel Forsey folding clasp in black titanium features a double folding mechanism with dual release pushers for additional security.
 
Fine Finishing and Aesthetics
 
As with all Greubel Forsey timepieces, the level of hand finishing and decoration throughout the Double Tourbillon 30° Technique is second to none. And the impeccable finishing goes much deeper than immaculate surface treatments as the components have been created with forms and shapes that highlight their beauty to maximum effect, offering myriad sublime details to be discovered and esteemed. Frosted plates, scintillating flat black‐mirror‐polished steel on flat and curved surfaces as well as the stunning bevels – many with sharp internal angles that machines cannot finish as well as a highly experienced hand – bring unparalleled vivacity. Large jewels set in polished gold chatons, and mirror‐polished and heat blued screws provide evidence of the extremely high quality that pervades every aspect of this timepiece.

Who's who

“The first time I met Robert Greubel, he was working on Richard Mille’s Planetarium Tellurium. When I saw him at work, I immediately understood that he was a real high-flier – and that at that altitude, he wouldn’t be meeting many other people.” Laurent Picciotto’s earliest memory of the co-founder of what was to become “Greubel Forsey” speaks volumes about the master watchmaker’s personality. For once, the term is no exaggeration: Robert Greubel really does master watchmaking, from design right through to the production of each component.

Robert Greubel grew up in Alsace and began his career in the family business, Greubel Horlogerie. He then moved to Switzerland to work for the International Watch Company (IWC), where he helped develop their Grande Complication. Three years later, he joined independent designers Renaud & Papi (later bought out by Audemars Piguet) as a prototypist for complications. He quickly rose to the position of managing director and then partner. At the turn of the century, his career took a new turn, too. In 1999, Robert Greubel began working independently and met his future partner, Stephen Forsey. Laurent Picciotto holds the latter in the same admiration: “As well as being a man of erudition, Stephen is also the kindest and most approachable person working in top watchmaking”, he says. Stephen Forsey’s career began in England: he was brought up in St Albans by his father, who was deeply interested in mechanics and engineering.

From 1987 to 1992, he specialised in restoring timepieces, becoming managing director of Watch Restoration in London. He travelled to and from Neuchâtel on numerous occasions to follow the WOSTEP watchmaking training course – until the day in 2001 when he made a one-way trip, settling down permanently in Switzerland to set up Complitime with Robert Greubel. Based in La Chaux-de-Fonds, the company produces complicated movements for major brands. Then in 2004, the two partners quit their jobs and officially registered their own brand, Greubel Forsey. “Initially, I was mostly aghast, largely due to their business model,” recalls Laurent Picciotto.

“Commercial strategy was the least of their worries; they were focused on doing extremely complex work in order to produce a tiny number of items... It was crazy!” Right from the start of that year’s BaselWorld, the brand’s degree of technical complexity made an impact. The very first timepiece was none other than a Double Tourbillon 30°. The brand’s DNA was already visible – a core business focusing on the tourbillon, with one hundred percent hand finishing to the highest standards of haute horlogerie. Stephen Forsey later explained that an item such as the Tourbillon 24 seconds requires 350 hours of work on finishings.

Harry Winston soon spotted the brand’s potential. As early as 2006, the firm entrusted them with the production of its Opus 6. From then on, Greubel Forsey continued to push back the boundaries of top watchmaking in a constant quest for precision, presenting outstanding items such as the Tourbillon 24 Seconds Incline and the Differential Quadruple Tourbillon. Such an unusual brand was bound to find its place in the Chronopassion collections: “Over time, Greubel Forsey has successfully made its mark with timepieces that ultimately, are self-evident for everybody. Stephen and Robert really are on a quest – they’re obsessed! Their fascination with mechanics is contagious. There’s a sense of “pure research” in their items. At the end of the day, you’re never sure of fully understanding a Greubel Forsey. That’s what makes them so special.”
