Figuring among the thinnest tourbillon skeleton self-winding movements in the world with its thickness of only 5.05 mm, the 1270S rose gold tourbillon skeleton calibre is instantly identified by its exclusive design. This movement's inverted structure shows on its display side its tourbillon, bridges and oscillating weight in rose gold-plated platinum. The off-centred micro-rotor and tourbillon cage, surmounted by a letter 'P' for 'Piaget' , intertwine to form an '8'. This unique structure displays all the watch's main functions – its self-winding mechanism, its driving force, its regulating system and its gear-train – together with its hours and minutes hands, which are also off-centred. Embellishing the rose gold of this 1270S tourbillon skeleton movement, its Haute Horlogerie finishes, entirely hand-crafted, are the result of complex techniques including hand-filed bevelling and mirror-polishing.
