Greubel Forsey – GMT Sport

Today, Robert Greubel and Stephen Forsey present their most sports-focused watch to date, the GMT Sport.

Featuring a lightweight, ultra-strong profiled titanium case, oval bezel and integrated lugs, the new timepiece is water-resistant to 100 meters/330 feet and powered by a new movement. 45mm diameter, case height 15.70mm, excluding sapphire crystal or 17.80mm.

To create an ergonomic case, Greubel Forsey designed an unusual shape that is round when viewed from above, but arched and oval when viewed from other angles.

Unique to this watch is the large satin-finished bezel, with the Greubel Forsey fake values ​​engraved in relief on the outer bevel.

Hours and minutes are indicated by concentric skeletonized hands whose curvilinear contours follow the curvature of the case and movement. To improve visibility in darker environments, the triangular tips of the arrow-shaped hands and the markings on the minute ring are treated with a luminous coating.

The secondary dial between 10 and 11 o’clock combines the small seconds on a large rotating disc and a second time zone display with hands.

Below it, the Earth’s rotating globe, seen from above the North Pole, completes each full counterclockwise rotation around its axis in 24 hours. Surrounded by a sapphire crystal ring, the 24-hour scale shows local time at all longitudes, as well as day or night (light/dark).

Two buttons on the left side of the case are used to adjust the GMT function: the first button selects the second time zone, and the other button is used to synchronize local time with global time.

At 3 o’clock we find a sector indicating the 72-hour chronograph power reserve, secured by two coaxial barrels in series. The power reserve differential is subtly engraved with Greubel Forsey values.

The 24-second tourbillon at 1 o’clock is held in place by a perfectly polished tourbillon bridge with a black-finish opening.

Greubel Forsey’s third fundamental invention in the field of tourbillons (after the double tourbillon 30° and the quadruple tourbillon) stands out with its 25° inclined cage completing a full revolution in 24 seconds. The higher speed combined with the special inclination of the cage improves the timekeeping performance of the single tourbillon system with minimal movement height. fashion fake watches

The rotating tourbillon cage with its adjustment mechanism is made up of 88 parts and weighs only 0.38 grams!

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 those time zones (on a light background) where daylight saving time applies from other time zones (on a dark background).

All 435 components of this hand-wound 3 Hz (21,600 vibrations per hour) movement, including the titanium bridges and bridges, adhere to the most exacting craftsmanship standards at Greubel Forsey.

The limited edition Greubel Forsey GMT Sport comes with a black or blue rubber strap that is secured to the wrist with a titanium folding clasp.
