Developed and made in Ateliers deMonaco’s manufacture in Plan-les-Ouates, the dMc-700 automatic movement is assembled by Maison’s passionate watchmakers. The masterpiece of this movement is its hand-engraved, 22-carat gold rotor which represents the Principality of Monaco’s coat of arms. Ateliers deMonaco is the only brand allowed to use this shield.

This traditional movement is encased by an 18-carat rose gold case magnified by 617 champagne-coloured diamonds, set to fit the shape of the case perfectly. In perfect harmony with the case, a delicate flower called King Protea is represented on the dial. Three rows of 24 lozenge-shaped settings welcome 120 champagne diamonds to create the corolla. The heart of the flower is made of white mother-of-pearl and is surrounded by a rose gold ring. Finally, to echo the colour of the white mother-of-pearl and the base of the rhodium-plated rose gold dial, a white alligator strap enhances the whole.

This new timepiece, La Sirène Champagne, is the fourth reinterpretation of the original La Sirène Topaze piece created in honour of HSH Princess Charlene of Monaco. This flagship model of the women’s Ateliers de Monaco collection is limited to 8 pieces only. An ideal and coveted gift for the holidays.
