Greubel Forsey GMT Sport Titanium

Already in 2015, the GMT Black paved the way for the GMT Sport. Building on this foundation, Robert Greubel and Stephen Forsey have invented and now present a lightweight and ultra-strong, profiled titanium case with ovoid bezel and integrated lugs to showcase the new movement. The new case form seems perfectly round from above, while revealing the accentuated arched and ovoid shape from other angles. The integrated lugs and strap shall offer a perfect fit on any wrist, thanks to a distinct functional form. The satin-finished bezel has Greubel Forsey’s values engraved on its outer bezel relief. An arched bridge and inclined gear train showcase an entirely new movement architecture.

The focus of the sporty GMT Sport is on legibility and efficiency. The hours and minutes are displayed by concentric openworked hands whose curved profile follows the curvature of the case and movement. Mounted on the suspended arch center bridge with black treated openings, the gear train literally follows the curve of the bridge, overlooking the globe to drive the hour and minute hands. The triangular tips of the arrow-shaped hands and the markers on the minute-hour-ring are enhanced with luminescent coating. An auxiliary dial between 10 and 11 o’clock combines the small seconds on a large rotating disc, and the second time zone display with a hand. The 72-hour power reserve (ensured by two coaxial barrels in series) is indicated on a sector at 3 o’clock with its openworked hand and highlighted red triangle. Housed underneath the arched bridge, the power reserve differential is subtly engraved with Greubel Forsey’s values.

The 24 Seconds Tourbillon is showcased at 1 o’clock secured by its distinctive and highly polished tourbillon bridge with black finished openings. It is already the third fundamental invention by Greubel Forsey in the field of the tourbillon (after the Double Tourbillon 30° and Quadruple Tourbillon) that stands out with its cage inclined at 25° completing one full rotation in 24 hours. The faster speed combined with the inventive cage inclination, significantly improves chronometric performance in a single-tourbillon system.

Already in 2011, Greubel Forsey has presented a remarkable GMT mechanism. In this double-patented mechanism, the second time zone indication on the auxiliary dial between 10 and 11 o’clock is combined with a universal time display to intuitively read the current time anywhere in the world. The striking spectacle of the terrestrial rotating globe performs each complete anticlockwise turn on its axis in 24 hours. It’s surrounded by a sapphire crystal ring with 24-hour divisions. Hence, the wearer can read local time for all longitudes, including the day / night indicator. On the caseback side of the GMT Sport, outer and central rings complete the sapphire cities disc to give UTC Universal and Summer Time for 24 cities in major time zones. This disc distinguishes those time zones applying summer time from those that do not. The GMT’s functions are controlled by two pushers located on the left side of the case.

Created in a limited edition of 11 pieces, the new GMT Sport is worn on a black or blue rubber strap. A titanium folding clasp reinforces the comfort and ergonomics of this remarkable Greubel Forsey timepiece.
