Greubel Forsey has unveiled an extraordinary timepiece, the Nano Foudroyante EWT, to commemorate its 20th anniversary. This watch represents the brand’s 10th Fundamental Invention, showcasing a groundbreaking approach to horology through the innovative application of nanomechanics.
Revolutionary Nanomechanics
At the heart of the Nano Foudroyante is a mechanism that operates at the nanojoule scale, drastically enhancing energy management within the movement. This advancement allows for a significant reduction in both energy consumption and the number of components used. Specifically, while traditional foudroyante mechanisms consume approximately 30 microjoules (μJ) per jump, the new Nano Foudroyante operates at just 16 nanojoules (nJ), marking a staggering reduction by a factor of 1,800. This innovation not only optimizes energy use but also minimizes the overall volume of the mechanism by 90%, leading to a compact design with only 428 components.
Design and Features
The Nano Foudroyante EWT is housed in a sleek 37.9 mm case made from white gold and tantalum, making it one of Greubel Forsey’s smallest creations. The watch integrates a flying tourbillon, which is a first for the brand, and features an innovative dial that remains aligned at twelve o’clock for optimal readability, regardless of the tourbillon’s rotation. This combination of features provides both aesthetic appeal and functional precision.
Key Specifications:
- Case Material: White gold and tantalum
- Limitation: Only 11 pieces will be produced
- Chronometric Power Reserve: One full day
