All brand Greubel Forsey watches introduced new and unique feature of GMT. During the last decade of the watch company Greubel Forsey created the latest in the world with a tourbillon mechanism. Today, Robert Grebel, and Steven Forsyth decided to join the new tourbillon complication GMT (Greenwich Mean Time) – second time zone function.
Practical and sophisticated function is highly regarded experts and is very effective when you travel.
True to his philosophy and constant striving for excellence and innovation, Greubel Forsey went far beyond the usual display second time zone. The function is characterized by a wonderful three-dimensional GMT temporary incarnation: a rotating globe, offering an accurate representation of the time anywhere in the world.
Located at around 8:00, “flying” globe is mounted on one end of the axis of rotation – the South Pole, which allows to reach hard-to-view surfaces, which are made of durable titanium.
While the earth makes one complete rotation 24 counterclockwise, which is the natural direction of rotation of the Earth, the position of the continents can be placed on a 24-hour display day / night set at the equatorial ring theme.
Nighttime hemisphere – from 18:00 to 6:00 – indexed for blackening half rings, frames the globe, while the daytime hemisphere – from 6:00 to 18:00 – indexed for white half. Thus, if in England, at noon, then the user will record the beginning of the afternoon in Geneva or Rome.
Following the intuitive interpretation, Globe added a mark of 10 hours with 12-hour second time zone display. Cascade clockwork around the dial is the main indexing device, which consists of minute-hour display in the position of 1:00, display small seconds hand at 2:00 position and power reserve indicator at 3 o’clock position. The mechanism of the model is complicated GMT 25 ° Tourbillon 24 Secondes cell at position 5 hours, which is considered one of the unique inventions of the company.
The disc marked the names of GMT 24 cities, each of which represents a time zone.
From a technical point of view, the mechanism model in terms of complexity in no way inferior to dial. In creating it used a full range of traditional techniques of decoration – corning, chamfering, grinding, lapping, polishing and glaze coating – perfect demonstration of know-how in the pursuit of perfection.
Mechanism itself consists of 436 components, 87 of which are used in cell weighing 0.36 grams of the tourbillon. Two coaxial barrels connected in series, provide 72-hour power reserve and carrying frequency of 21 600 pc / h. Dial in 18 carat gold and the entire mechanism enclosed body of white gold with a diameter 43.50 mm and 16.14 mm in height. Convex sapphire crystal with anti-reflective coating serves as the protection of the dial, transparent case back and side screen.
