Mother of pearl dial The popular silhouette of the Aquis Date diving watch forms the basis for each of the three models, which will be remembered primarily for their contrasting dials in Blush Pink, Aegean Blue and Seafoam Green. Crafted from mother-of-pearl, the dials shimmer in the light like the surface of the water at sunset, adding an elegant, sophisticated tone to the Aquis' high-performance profile.
