Michael Jordan was spotted at the NASCAR Cup Series DuraMAX Texas Grand Prix wearing an ultra-rare Greubel Forsey Invention Piece 3 ‘Salmon’ (Tourbillon 24 Secondes) in platinum. The Invention Piece 3 houses Greubel Forsey’s signature 24-second inclined tourbillon (GF 01N, hand-wound), a 43.5 mm platinum case with lateral sapphire window, rapid-rotating twin barrels, and a ~72-hour power reserve. Finished with hand-engraving, a sapphire caseback and a fully architectural open dial, this reference was produced in extremely limited runs (only 11 pieces in platinum). #GreubelForsey Retail price: $ 600,000.00 Photo: foxnews
