Aventurine is a precious glass of blue color, enriched with copper inclusions that give it a distinctive sparkling effect. Its origins date back to the early 17th century, attributed to Venetian glassmakers. Currently, this material is mainly used in the creation of art objects and is appreciated for its ability to reflect light in a unique way.

In the 17th century, the name "aventurine" originated from "avventura," meaning an uncertain and risky operation. Venetian glassmakers first produced aventurine by accident, spilling copper fragments into blue glass paste. By 1644, the technique was codified, and Venetian aventurine artifacts became highly prized. The lithograph depicts the Doge visiting workshops on Murano, the center of glass production.

Aventurine is a challenging material to tame, precisely because of the copper fragments inserted into the molten glass, which arrange themselves uniformly during the slow cooling process. To create components with a high degree of precision, aventurine is cold-cut, as if it were a hard stone. Today, the production of this material is still very limited precisely because of its complexity and the significant know-how required.

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.
Aventurine Dial
A constellation of tiny fragments of light stands out against the deep blue of aventurine, evoking the dense mystery of the stars and the darkness of the universe. The rehaut completes the design of the dial and features a sunray texture that provides further complexity to the whole.

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.
A Versatile Diver
Nereide Avventurina makes a strong point of its versatility. In addition to the aventurine dial being undoubtedly eye-catching, the extreme resistance granted by tungsten and sapphire crystal makes this timepiece perfect for everyday use too.

Swiss Super-LumiNova® BGW9
Swiss Super-LumiNova® BGW9 is a luminescent pigment which is sensitive to sunlight or artificial light. It is white in daylight and, once it is charged, it emits a bright blue-green glow in low light conditions, making it the solution of choice in watchmaking.
