This dial features diamonds set in 18 ct gold. Its natural mother-of-pearl surface reveals unique shades and patterns—never artificially coloured and always preserved in its original beauty. No two dials are ever alike, making each watch truly one of a kind.
Gem-setting is a meticulous craft where each stone is hand-shaped, precisely aligned, and securely set in precious metal. The harmony of proportions, consistent height, perfect orientation, and refined finishing creates a radiant, captivating brilliance on the watch.
