Steve Forsey

Greubel Forsey is somewhat different that any other brand. They don’t really make watches but rather Inventions. They do let their imagination guide them but these inventions are rather codified within the realm of Horology. While a few new brands want to approach watchmaking without any boundaries, Stephen Forsey and Robert Greubel are watchmakers, their watchmaking is as rigorous as a Dufour. Incidentally, Philippe Dufour works on a few projects with the two watchmakers. Maybe the biggest compliment of all.


Steve’s watch, a Double Tourbillon Asymétrique

THE GMT
The GMT features a second time zone indication complemented by a three-dimensional globe providing an intuitive picture of time all over the world, all set in a distinctive asymmetrical case.

A dual-function pusher allows quick setting of the second time zone, indicated on a small dial at 10 o’clock as well as adjustment of the rotating globe. Accuracy is assured by the 25° inclined Tourbillon 24 Secondes regulator, while a 72-hour power reserve indicator at 4 o’clock monitors available power.

On the back of the timepiece, a worldtime disc with cities in each of the 24 time zones facilitates the setting of the globe and provides an alternative view of universal time.

The Double Balancier 35°
The Double Balancier 35° features two inclined fixed-oscillators coupled with a spherical differential, which provides the average of their rates to the gear train and time display.

Between the two visible inclined balances, small seconds at 7 o’clock displays the running instantaneous average of the two regulators, while a 72-hour power reserve indicator at 2 o’clock keeps track of the optimal power available from the two co-axial, fast-rotating mainspring barrels.

The 35° inclination of the balances allows for larger diameter balance wheels (better inertia /more stable timekeeping) in a 43.5mm case.

The Double Balancier 35° is a unique edition of six pieces in 18k white gold.

THE EWT
Greubel Forsey Experimental Prototype. The company presented in 2005 a proprietary development methodology called EWT (Experimental Watch Technology) to experiment, test and ratify their projects in-house. It’s a proprietary research and development platform.

THE QUADRUPLE TOURBILLON
The spherical differential linking the four tourbillon carriages of the Quadruple Tourbillon is a prime example of Greubel Forsey’s inventive approach, as it exhibits an unprecedented degree of complexity, refinement and timekeeping performance.

Four asynchronous tourbillons independently contribute to its high precision. The spherical differential acts like a car’s differential in distributing torque between two wheels while allowing them to rotate at different speeds.

The asymmetrical format of the two double tourbillons provides clear visibility to all carriages on the dial side, enables an additional lateral view through the side-window and eliminates the necessity for a larger movement diameter – all in a highly distinctive elegant case.

DOUBLE TOURBILLON 30° BLACK TITANIUM

My favorite watch
At the heart of this 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.
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.

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. This particular Tourbillon 30° is made in black titanium.

The Tourbillon 24 Secondes Contemporain
The Tourbillon 24 Secondes Contemporain is characterised by its round case and emphasis on the technical aspects of the movement, especially the tourbillon. The three-dimensionality of the timepiece is accentuated by the royal blue treatment of the titanium plates and bridges.

A transparent synthetic sapphire tourbillon bridge gives a captivating and hypnotic impression of the regulator floating in mid-air and underlines one of the highly creative challenge which are to be found throughout the timepiece. The distinctive 12 o’clock index in relief is an example of the innovative spatial management of the components within this architectural study.

The Tourbillon 24 Secondes Contemporain is a unique edition of 33 pieces featuring a titanium movement and platinum case.

ART PIECE 1
Art Piece 1 is a collaboration between Greubel Forsey founders Robert Greubel and Stephen Forsey and renowned British micro-sculptor Willard Wigan.

The real challenge, however, lies in the integrated optics, there is a miniature microscope set into the caseband, allowing the wearer to fully appreciate the detail of Wigan’s nano sculpture. This optical-grade instrument offers 23-fold magnification, with the timepiece cleverly designed to allow enough natural light to illuminate the sculpture.
