Launched in 2011, this watch features the hand-wound MB M65.63 caliber inside an oversized case with a 6 o'clock bulge dedicated to the 'mysterious' hours and minutes. It is the inaugural wristwatch to utilize a tourbillon with double cylindrical balance springs, a concept originating from 18th-century marine chronometry. The opposing respiration of these springs ensures consistent torque, significantly improving the precision of the movement. Limited to 8 pieces.
