Caliber JCAM51 is one-of-a-kind. There is no other mechanical movement delivering a roulette table experience such as this one. With its design details, the high-performance flying tourbillon is turned into an element of that roulette. The pusher at 7 o’clock starts the spinning of the roulette table. Developed exclusively by Jacob & Co., the table is mounted on highly efficient ball bearings. They allow it to spin fast and smoothly until the white ceramic ball finally lands in its pocket. This complication is a Jacob & Co. exclusive.
