Inspiration

For the new ETHERAL collection, the first with a round case in the brand's history, we embarked on a project to create a watch of utmost refinement, combining modern/futuristic aesthetics with state-of-the-art mechanics. A project that started in 2018 and became a reality in 2024. The starting point was to combine kinematics with an innovative new movement. The dial had to be mobile and striking at first glance. What elements should be placed on the dial? The choice fell on the oscillator associated with the digital time display. The result is two flying tourbillons and an original jumping hour display, giving the dial a powerful and appealing appearance.

About the Etheral Twin Orbital Tourbillon

The year 2024 marks a new milestone in the brand’s history with the introduction of the new ETHERAL collection featuring a round case, a first for the Maison. The “Twin Orbital Tourbillon” is the first member of this new line. A creation which combines the manufacture’s best skills and know-how in a daring and innovative kinematics, equipped with the new in-house hand-wound calibre CYR518-E that boasts three patents pending.

The stars of the mobile 3D dial are the jumping hour indication by means of two truncated cone-shaped discs inclined at an angle of 18°, surmounted by a highly original triangular minute hand, and the two inclined flying tourbillons that appear to be suspended in mid-air. Positioned on a frame, all these components perform a spectacular dance.
