The Greubel Forsey GMT Quadruple Tourbillon Explained: A Deep Dive With Stephen Forsey (Video)
Forsey reveals interesting facts, while the macro footage also reveals closeups of the charming three-dimensional globe, the “iconic” side view of the case revealing this globe in a side window, and the amazing finishing on the individual components for which Greubel Forsey is renowned.
Here TheWatchesTV allows us to take a deep-dive view of the ultra-complicated Greubel Forsey GMT Quadruple Tourbillon with Stephen Forsey, and no corner of this timepiece is left unturned (or unfilmed).
As Marc André says, “This timepiece is a condensed version of what Greubel Forsey is all about: extreme technicality and extreme finishing.”
