There is so much going on with this watch that it would be easy to get lost. So let's start from the outside and move inward. The asymmetrical case is unique to Greubel Forsey and was designed with a few goals in mind. Importantly, it lets the central round footprint to remain under 44mm (43.5mm to be exact), making the watch relatively wearable. Also, the asymmetric shape creates volume where it is needed around the tourbillon and highlights the mechanism with a viewing window on the side of the asymmetric "bubble" by 7 o'clock.

That brings us to the tourbillon itself. This is a pair of nested tourbillons, with the inner tourbillon set off 30 degrees in relation to the outer cage (over 130 components are required for this part of the movement alone). This was Greubel Forsey's first invention and it combines better timekeeping accuracy with sheer beauty and Greubel Forsey really knows how to emphasize the latter. Finishing is unbelievable here and the balance seems to float and spin effortlessly in its little bubble. Next to this you'll find the small seconds indicator moving in synch with the outer tourbillon.
