24 Second Asymetrique Tourbillon Platinum LE
Probably the best bargain the GF lineup, this is a SUPERWATCH in the mortal realm. The 24-second incline tourbillon is the invention from Invention Piece 3, and is the same tourbillon used in the GMT, Perpetual Calendar EOT, and even the Grand Sonnerie. 24 seconds is super speedy: very cool visually both from the top and through the side window.
This one is platinum with a multi-level anthracite dial unique to this version and unique within the entire Greubel range. It gives the watch a super contemporary look that can work both casual and formal
