Back in 2015, the GMT Black paved the way for the GMT Sport. Building on this, Robert Greubel and Stephen Forsey invented and launched a lightweight and ultra-strong profiled titanium case with an oval bezel and integrated lugs , to showcase the new movement. The new case looks perfectly round from above, while showing off the prominent arches and ovals from other angles. Thanks to the unique functional form, the integrated lugs and strap fit perfectly on any wrist. Greubel Forsey values are engraved on the outer ring of the satin bezel in relief. Arched bridges and sloping gear trains showcase the new movement architecture.
The focus of the sporty GMT Sport is legibility and efficiency. Hours and minutes are indicated by concentric skeletonized hands whose curvilinear contours follow the curvature of the case and movement. The gear train is mounted on a suspended arched central bridge with black treated openings, following 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 ring are coated with a luminous coating. The subdial between 10 and 11 o’clock combines the small seconds on a large rotating disc and a second time zone display with hands. The 72-hour power reserve (guaranteed by two coaxial barrels in series) is shown on a sector at 3 o’clock, with its skeletonized hands and a highlighted red triangle. The power-reserve differential under the arched bridges is subtly engraved with Greubel Forsey values.
The 24-second tourbillon is located at 1 o’clock, and its unique and highly polished tourbillon bridge has a black-finish opening. Already the third fundamental invention of Greubel Forsey in the field of tourbillons (after the 30° double and quadruple tourbillons), its cage is inclined at 25° and can complete a full revolution in 24 hours. The higher speed combined with the innovative frame inclination significantly improves the timekeeping performance of the single tourbillon system.
Back in 2011, Greubel Forsey fake introduced the remarkable GMT mechanism. In this dual-patented mechanism, the second time zone display between 10 and 11 o’clock on the secondary dial combines with the universal time display to visually read the current time anywhere in the world. The spectacular sight of the Earth Rotating Globe completes each full counterclockwise rotation in 24 hours. It is surrounded by a sapphire crystal ring with a 24-hour index. Thus, the wearer can read local time at all longitudes, including day/night indicators. On the back side of the GMT Sport, the outer and central rings form the sapphire city disc, providing UTC Universal Time and Daylight Saving Time for 24 cities in the main time zones. The disc distinguishes between time zones where daylight saving time is applied and time zones where daylight saving time is not applied. The GMT functions are controlled by two buttons located on the left side of the case.
The new GMT Sport is available as a limited edition with a black or blue rubber strap. A titanium folding clasp enhances the comfort and ergonomics of this exceptional Greubel Forsey replica watches online.
