The Nano Foudroyante EWT (Experimental Watch Technology) is a major technological leap, comparable to the transition from tower clocks to wristwatches. Originally, horological instruments were large and public. They became transportable (table clocks, marine chronometers), then portable with pocket watches, and finally wearable with wristwatches.  This evolution reaches its peak today with nanomechanics—a revolution Greubel Forsey is pioneering. 

What is nanomechanics? It is the miniaturization of components to the nanometric scale. The mechanism’s energy is managed at the nanojoule scale, significantly reducing the number of components and the overall dimensions. The result is a 37.9mm timepiece that combines the world’s first perpetual Nano Foudroyante with Greubel Forsey’s first flying tourbillon and manual wind flyback. 

The new Nano Foudroyante is crafted entirely in white gold, the gold dial is now finished in rhodium with a blue minute track, while the hands are rendered in blued steel with matching cannon pinions.

Created for 22 collectors who will experience Greubel Forsey’s most energy-efficient, compact, and conceptually advanced timepiece to date.
