The dial on this watch is made of intricate mother of pearl put together in a mosaic pattern. What is Mother of Pearl? Unsurprisingly, pearls and mother of pearl are made of the same substance: nacre, an iridescent material composed of calcium carbonate. Nacre is created by mollusks to protect their soft interior tissue. Mother of Pearl is believed to have stress-relieving properties, bringing calmness and stimulating intuition and creativity. This elegant watch is fitted with 4 crystals in the dial and is made of corrosion-resistant stainless steel.
