The captivating sight of the world's thinnest self-winding flying tourbillon
In 2015, the Parmigiani Fleurier watchmaking centre presented an ultra-thin tourbillon, a technological feat resulting from two years of research and development. Its 3.4-mm-thick calibre made it the thinnest self-winding flying tourbillon in the world. In 2017, the spotlight was back on the Tonda 1950 Tourbillon, which was unveiled in a version with an Abyss blue dial and a white gold case.
FEATURES OF AN ULTRA-THIN CALIBRE
The calibre PF517 owes its thinness to a micro-rotor made from 950 platinum and a precise arrangement of the movement components. The flying tourbillon, the barrel and the micro-rotor are arranged on the same main plate, which means there are no successive levels to increase the thickness, and the time display is kept central – a rarity for an ultra-thin tourbillon.
