Greubel Forsey GMT Platinum

New in platinum, the Greubel Forsey GMT combines the brand’s signature inclined tourbillon with a dual time zone and world time display that is linked to the three-dimensional globe on the front of the watch.

The 24-second tourbillon is inclined at 25°, meaning it rotates once every 24 seconds on a plane at a slight angle to the dial.   The dimensional sphere representing the Earth indicates day or night of any point on the globe.   Above this is the second time-zone hand (set in one hour increments by the “GMT” pusher on the side of the case).  Hour and minutes with small seconds sub-dial, and a power reserve indicator (far right) round out the black dial.  Which, by the way has a very nice looking finely grained texture to it.

On the back is the world time disc showing the time in 24 time zones, and as noted above, it moves in tandem with the globe on the front.  While the earlier gold versions of the GMT had grey dials, the GMT Platinum has a black dial. The case remains the same dimensions at 43.5 mm wide and 16.14 mm high.  Of course the watch is finished to the highest of standards.

This is multi-dimensional creation is truly something special cased in platinum (43.5mm x 16.14mm).  Like all Greubel Forsey pieces, this is a watch for only the most deep-pocketed collectors (price is in the range of $600,000 – $700,000).

Greubel Forsey Tourbillon 24 Secondes Contemporain Titanium

This new piece from ultra high-end watchmaker Greubel Forsey features a movement crafted of titanium and is available in a choice of red or white gold case, with production limited to just 33 pieces of each.  The “Tourbillon 24 Secondes Contemporain with natural titanium movement” has a sober architecture while putting on display Greubel Forsey’s third invention, the Tourbillon 24 Secondes mechanism (see Did You Know? below).  The mechanism is supported at 6 o’clock by a barely detectable transparent sapphire bridge (close-up photo below).

There is a striking sense of depth to the dial as emanated by the arrangement of various components:  the twelve o’clock stands out for being not only the sole numeral (in red or white gold) but also for being raised, descending separately from the raised sapphire chapter ring; the ‘floating’ tourbillon; and the long central tripod for the hour and minute hands.

Color elements also play an important design role — darker details on the display such as the power reserve indicator at 4 o’clock, small seconds at 9 o’clock or the 24 seconds tourbillon at 6 o’clock contrast with the light grey of the natural titanium movement and integrated titanium bridges.

On the back of the watch, three NAC-treated anthracite bridges can be seen through the sapphire crystal display back.  Greubel Forsey’s expertise in extremely fine hand-finishing should not go unnoticed:  mirror-polished bevels (many of which feature internal angles), mirror-polished countersinks, straight-graining and snailed decoration on the mainspring barrel.  GF also points out that there are also discrete nods to tradition on this contemporary timepiece, for example the domed olive jewels and heat blued screws, which pay elegant homage to master watchmakers of the nineteenth century.

In this closeup, you can see the movement bridges in nickel silver with ruthenium plating which gives them a much darker shade of grey:

Fine specimens of high watchmaking, no doubt!  Price will about $450,000, give or take.

Did You Know?

The Tourbillon 24 Secondes is Greubel Forsey’s third fundamental invention, a highly-efficient, fast‐rotating – 24‐second revolution – tourbillon cage inclined at 25°, which minimises negative effects of gravity on the oscillator, particularly in stable positions.

SIHH 2013…In addition to its Art Piece 1, Greubel Forsey presents a second new piece at SIHH 2013, the Greubel Forsey Double Tourbillon Technique Black.  Of note, this is the first black timepiece in Greubel Forsey collection (excluding some special, one-off pieces), and it is also the first in the GF collection to have a a titanium case and rubber  strap.  Prior Double Tourbillon Technique pieces were offered in red and white gold.

The Double Tourbillon Technique Black features a unique, open-architecture in an entirely original and innovative interpretation of Greubel Forsey’s first fundamental invention (2004), the Double Tourbillon 30°.   GF notes that “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.”  The Double Tourbillon 30° mechanism sits at 6 o’clock, with the unobstructed configuration of the open movement allowing full appreciation of the duo of 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 additional depths of the open dial.  The red-tipped, four-pointed, sapphire crystal indicator 6 o’clock rotates in four minutes above the double tourbillon, and indicates 0-60 seconds along a quadrant.

Greubel Forsey Art Piece 1 with Willard Wigan (SIHH 2013)

SIHH 2013…

Greubel Forsey Art Piece One Willard Wigan

I caught a sneak peek at this piece back in October, but the full reveal of the Greubel Forsey Art Piece 1 (done in collaboration with out-of-this-world talented microsculptor Willard Wigan) was not meant to be.  Now here it is, though it is still presented by Greubel Forsey as a “work in progress.”.  The quick premise is that there is a microsculpture in the left side of the watch.  The crown looking device on the left is actually a magnifying glass of sorts — perhaps microscope is a better term — so that you can see the microsculpture that Willard Wigan has created inside of the Art Piece 1.  The magnification is 23x and due to the nano-nature of Wigan’s work, this is the only way to appreciate Wigan’s microsculpture. Refer back to my original preview for more background on Wigan and the jaw-dropping mind blowing work that he does. And now to see if encapsulated in a Greubel Forsey timepiece — well, this is really something special.  Note also that Greubel Forsey have decided to include their first fundamental invention — the Double Tourbillon 30° — in the Art Piece 1.
