To celebrate its 20th anniversary, Greubel Forsey unveils its 10th Fundamental Invention, the Nano Lightning EWT. This revolutionary timepiece, limited to 11 copiesintroduces nanomechanics in watchmaking with energy management at the nanojoule scale. With a diameter of only 37.9mmit embodies the innovation and know-how of the workshop, integrating the first perpetual foudroyante and a flying tourbillon.

Nanomechanics: a new horizon for watchmaking

There Nano Lightning represents a major advance. Nanomechanics makes it possible to reduce bulk and energy consumption, thus transforming the traditional approach to watchmaking. By controlling nanojoule energy, Greubel Forsey has designed a perpetual lightning bolt that consumes 1,800 times less energy than conventional models. This mechanism, which only consumes 16 nanojoules per jump, also reduces the volume of the mechanism by 90%.

Flying tourbillon and manual flyback mechanism

This timepiece incorporates the first flying whirlwind by Greubel Forsey, offering constant rotation with a lightning dial always aligned for optimal reading. This model also has a flyback function, supplemented by a column wheel visible on the back side, and a one-day power reserve, even with the chronograph activated.

A rare and precious design

The box combines white gold And tantaluma first for Greubel Forsey. This complex material to work with gives unique blue-gray reflections, adding an exceptional character to the aesthetics of the model. Engraved with the words “2004 – 2024” and “20th Anniversary”, this limited edition underlines the exclusive nature of this revolutionary creation, inspired by 20 years of innovation.
