Design & Craftsmanship
A Refined Expression of Complex Watchmaking
The Master Control Chronometre Perpetual Calendar blends technical sophistication with elegant design, featuring a bronze-toned sunray dial that complements the warm hues of the pink gold case and bracelet.

The four sub-dial layout delivers a balanced and highly legible display, enhanced by contrasting opaline rings and azuré finishes. At 6 o’clock, the hammered gold moon phase adds depth and artisanal detail, evoking a sense of celestial refinement.
