Reverso Hybris Artistica Calibre 179

Designed according to the proportions of the Golden Ratio, a theme that runs through the 2023 collections, the Reverso confirms it is a canvas for artistic expression at Jaeger-LeCoultre, which presents the Reverso Hybris Artistica Calibre 179. The movement, Calibre 179, benefits from the fourth evolution of the Gyrotourbillon. It is also a Duoface movement, hence displays a different time zone on each dial with a day/night indication on the reverse dial. Assembled from 123 components, the Gyrotourbillon comprises a titanium carriage and a peripheral carriage mounted on ball-bearings. These two elements turn perpendicularly to each other at different speeds: once every 16 seconds for the inner carriage and once per minute for the peripheral carriage, which also provides a small seconds function. Closer inspection reveals a semi-spherical balance spring as well as the Gyrolab balance whose double-anchor shape reduces air friction. Each of the watch’s “two faces” has a distinct personality. On the front side, in an allusion to the Art Deco style, a lattice of gold lines contrasts with the blue lacquer background. On the skeletonised reverse side, blue lacquer highlights the hours-minutes ring and its supporting bridges. This complex movement is housed in a generous 51 x 31mm case in rose gold. Production is limited to ten pieces.
