The Case

Carved in 5N Rose Gold

The case is crafted in 5N 18K rose gold (Au750) and enhanced through hand carving. This additional layer of workmanship introduces texture and depth, transforming the case into a sculptural surface while preserving its architectural clarity.

Black onyx dial with rose gold indexes

The Dial

Black Onyx

Executed in black onyx, the dial presents a dense, uniform surface with natural depth. Rose gold indexes bring warmth and precision, establishing a refined contrast against the dark mineral plane.

The Hands

Rose Gold in Motion

Crafted in rose gold, the hands feature polished, domed and lightly hammered finishes. Their warm tone reinforces the continuity between the carved rose gold case, the rose gold indexes, and the black onyx dial.

The Movement

A Unified Architecture, Finished in 5N

The hand-wound calibre is finished in a 5N-toned treatment, extending the chromatic language of the carved case into the movement. This continuity reinforces the coherence between exterior craftsmanship and mechanical structure.
