Manufacture Piaget 670P ultra-thin, hand-wound mechanical movement (4.6 mm) Developed to fit perfectly in an Altiplano case, the 670P ultra-thin hand-wound mechanical tourbillon movement is the first tourbillon from this iconically slender line. This round-shaped movement consisting of 157 components is only 4.6 mm thick and features a patented arbor winding system with setting wheel and a new barrel providing a power reserve of 48 hours. Formed by three titanium bridges, the ultra-thin flying tourbillon cage is suspended on a single axis and weighs only 0.2 grams. Positioned at 2 o’clock, it forms a figure eight with the off-center hours and minutes counter at 8 o’clock, and indicates the seconds via one revolution per minute.
