Traditional to radical: new tourbillons at SIHH 2019

Now that the market is back, so is the tourbillon, with futuristic designs, new materials and sometimes radical aesthetics Girard-Perregaux ambitiously depicts all 12 constellations in 3D, the entire earth in 3D, a day/night indicator, a GMT second time zone along with the tourbillon escapement, all on a 48mm canvas This watch challenges the traditional aesthetics of the tourbillon, taking the concept of skeletonization to the next level with a transparent sapphire crystal case.

The movement, a flying tourbillon, was built from scratch to fit the inclined case The movement is a dual flying tourbillon that, like all Roger Dubuis watches, is finished to Poinçon de Genève standards This piece is a little more on the traditional side, even with its 9'oclock tourbillon position and off-centred moon phase and power reserve.

The blue lacquered dial, the Poinçon de Genève hand-finished movement and, of course, the tourbillon escapement keep it within the realm of fine watchmaking. . Source
