Skeletonized dial. The hour and minute hands circle directly above the movement and point to two zones calibrated with Arabic numerals. The power-reserve indicator at 8 o'clock displays a field and a two-part hand that share a distinctly three-dimensional nature. The main element in the dial is the triaxial tourbillon. The first carriage--the biggest--holds the other two, and takes 300 seconds to rotate on its axis. It encloses an intermediate carriage, which spins in 75 seconds. The third, and smallest, carriage directly holds the large variable-inertia balance wheel and completes its rotation in 45 seconds.
It comes on a black alligator leather strap with stitching in 18kt rose gold or platinum thread. Ardillon buckle in 18kt rose gold or white gold.
