With mother-of-pearl, nature has provided us with an especially beautiful material for jewelry. Its iridescent shimmer has long fascinated mankind, and artisans learned long ago to adorn precious objects with mother-of-pearl, such as inlays in beautiful furnishings made of precious woods. Various sea snails and pearl oysters form mother-of-pearl layers on the interior of their shells. In scientific terms, these coatings consist of calcium carbonate platelets. It is precisely this material that oysters use to render foreign objects such as grains of sand harmless by coating them with numerous layers of mother-of-pearl, thus transforming them into pearls. Shimmering mother-of-pearl in white, light blue or pink are the options available for the dials of the 456 series. Whether in the steel watch or - if desired - with the decorative gold ring around the case, the shimmering dial gives these ladies' watches a completely new vibrancy. The pastel colors match everyday clothing as well as elegant evening attire equally well. Model 456 with the mother-of-pearl-dial is made exclusively with Roman numeral appliqués; it shares all technical features with the other models of the series.
