Between Science & Elegance
The Léon collection pays tribute to the ingenuity of Léon Foucault, the man who made the world turn… quite literally. Inspired by his famous pendulum, designed to demonstrate the Earth’s rotation, this creation reflects the pursuit of balance and precision at the heart of watchmaking. Pure lines, a play of contrasting finishes, and a design in constant motion: Léon embodies the dialogue between science and elegance.
‘Inertie,’ a symbol of mastered time.
The linen dial of the Léon collection reveals time in its most essential form. Its natural texture subtly captures the light, offering soft and lively shades depending on the viewing angle. Minimalist and authentic, it expresses a calm, sincere, and controlled way of reading time. The dauphine hands and applied indices are enhanced with Super-Luminova, providing an elegant reading of the time, even in complete darkness.
The Engine of the World
At the heart of the Léon collection beats the Miyota 9015 automatic caliber, renowned for its reliability and finesse. With a 42-hour power reserve, it keeps time with consistency and precision. The transparent case back reveals the engraved oscillating weight, paying tribute to the genius of Léon Foucault and his Pendulum. Each rotor is also engraved with a unique serial number, from 000 to 100, highlighting the exclusive nature of the piece.
