Ultra-thin self-winding watch in white gold. Black off-centre dial. Black alligator-skin strap. A mere 4.30 mm in thickness, this automatic watch for men is one of the thinnest in the world. Its secret lies in the unique design of the white gold case, whose case back serves as the plate to which 219 components are affixed. This complex structure fuses movement to case. Depending on an inverted construction of the calibre, with its bridges mounted on the dial side, it gives a result that is both technically and aesthetically effective. The whole mechanism and hand system is contained within the height of the balance, with an off-centre hours and minutes display. Within this extremely limited space, Piaget has designed a suspended barrel, held in place solely by a single bridge on the dial side, and a peripheral 22K gold rotor coated with black PVD.
