About the collection
The Quadruple Tourbillon, introduced in 2008, combines two double tourbillons in one movement, linked by a differential so that their rates are averaged. It is one of Greubel Forsey's most complicated designs.
The catalog lists the original version, the Black and Blue versions and the Quadruple Tourbillon Secret in platinum and red gold, whose dial side hides most of the mechanism. Each was made in small numbers, so the certificate, full set and a service history from the brand are essential.
