Geneva / Grande complication

Calibre Souverain

An open-worked calibre in rose gold, rhodium, blued steel, and aventurine. Six layers. One controlled reveal.

Foundation

Skeletonized main plate

Open bridges establish the calibre's architecture. Rhodium spans, mirror bevels, blued screws, and ruby jewels set the first plane.

Train of time

Brass and rhodium wheels cross the centre line with deliberate spacing, turning density into a readable mechanical rhythm.

Lower cage

The cage settles low in the movement: rose-gold arms, fine spring work, and polished pivots held against the dark aperture.

Moonphase arc

Aventurine interrupts the steel with a quiet celestial register, giving the open-work dial its traditional counterpoint.

Case and chapter ring

The case arrives last as a frame, not a cover. Black enamel tightens the perimeter while the rose-gold bezel keeps the light warm.

Dauphine hands

The display stays spare: faceted rose-gold hands, ivory inlay, and a blued seconds line over the completed calibre.

Private appointment

Viewings are held in Geneva, Paris, and New York for collectors who want to study the finished calibre before allocation.
