Greubel Forsey is a watchmaking company specializing in high-end timepieces. This was launched in 2004 by Robert Greubel and Stephen Forsey and is based in La Chaux-de-Fonds, Switzerland. The watch features Greubel Forsey’s own invention, the Double Tourbillion, which works to override the effects of temperature, magnetic fields, and movement — all of which can affect the precision of the timekeeping.
The case: The case comprises four different parts and measures 43.5mm in diameter. It is asymmetrical in order to accommodate the movement without having to resort to an overall larger diameter.
The quadruple tourbillon mechanism: The main feature of the watch is its quadruple tourbillon mechanism. It comprises two pairs of tourbillons, each with one inside the other. Each pair of tourbillons contains 128 components but weighs just 1.17g.
The movement: The movement, which took five years to develop, contains 531 individual parts, each specifically designed for the watch. The polishing and decorating of the movement components alone requires 500 hours of work.
The dial: The dial shows hours, minutes and seconds and fuses a force hold show, which demonstrates when the watch should be re-wound. At the point when completely twisted, the development will run independently for around three days.
Components: The watch highlights three individual sapphire precious stones, one of which is fitted into the back of the case and encompassed by a bezel that is hand punched and engraved in bas-help, a procedure which takes five days to finish.
Rarity: The Greubel Forsey Quadruple Tourbillon is the world’s first fourfold tourbillon wristwatch. Close to six can be made every year, an irregularity reflected in the cost.
