42mm case, the case middle and lugs made of grade 5 titanium and bezel and caseback made in platinum. The heart at 6 o’clock is formed by an intersection of the two skulls on the dial : framing a red gem in the center of the hidden tourbillon cage. Visible only when the slider of the repeater is activated, the chimes of the minute repeater carillon sound while another mechanism simultaneously separates the two skulls to reveal the tourbillon. Manual-winding movement Caliber SMC01, with 72-hour power reserve. Unique piece. Priced at US$414,000.00
