Mother-of-pearl is a precious natural material that forms inside the shells of mollusks such as oysters. Characterized by its unique iridescence, mother-of-pearl is admired for its range of colors and reflections. In the case of Nereide Madreperla, green has been chosen, evoking the magic and intensity of the aurora borealis, giving the watch a distinctive and captivating charm.

Mother-of-pearl requires meticulous craftsmanship during the production process. After careful selection, the raw material is meticulously polished and shaped to achieve a smooth and uniform surface. Through a delicate dyeing process, the mother-of-pearl is transformed into its distinctive green color while preserving its natural beauty. With skill and precision, artisans manually apply the indices, completing the creation of a dial that is a work of art in itself.

Tungsten Bezel Insert
Tungsten is the hardest and most resistant metal known to mankind.
It has a melting point of 3400°C, which makes it the most heat resistant metal. Its resistance to wear is equally incredible. Tungsten is, in practice, scratchproof and therefore it maintains its physical and aesthetic features unchanged over the years.
Mother-of-Pearl Dial
The use of mother-of-pearl gives the watch vibrant reflections. The surface of the dial comes alive with a variety of colors and shades, which merge into a breathtaking visual experience. Mother of pearl adds natural luminosity to the dial, creating an effect that gives the watch a unique and irresistible charm.

The submarine Nereide, which inspires the entire collection, is depicted submerged in the engraving at the center of the caseback, to remind how this watch doesn't compromise on underwater performance, retaining the ability to dive up to 200m deep and the rotating bezel that allows monitoring of dive times.
