It is said that in the 14th century, the name "aventurine" derived from the term "adventure," indicating an uncertain and risky operation. In fact, the Venetian glassmakers who first produced aventurine did so by accident, spilling copper fragments into a blue glass paste. From 1644 onwards, the processing technique was codified, and Venetian aventurine artifacts soon became the most prized of the era. The lithograph represents a visit by the Doge to the workshops on the island of Burano, the production district for this glass.

Aventurine is a difficult material to master due to the copper crystals that are inserted into the molten glass and evenly distributed during the slow cooling process. To create components with a high degree of precision, Aventurine is cold-cut, like a hard stone. Today, the production of this material remains very limited due to 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.
Cal. V3250
Produced in the Swiss facilities of Soprod SA, the V3250 is an automatic movement based on the M100 caliber architecture. The elaborate skeletonization of the new rhodium-plated rotor—designed to further enhance the movement's details—contrasts with the essential sandblasted decoration of the bridges, making the V3250 a movement with a refined and modern aesthetic.
The Perfect Fit
Versatile Elegance
The 39mm Nereide case embodies simple elegance and quality. With satin and polished finishes, it represents a perfect balance between refinement and practicality. This watch comfortably fits the wrist, adding a touch of style to any setting, whether sporty or elegant.

Extremely Thin
With a thickness of only 10.4mm, our new 39mm Nereide combines elegance and practicality. Thanks to the thin and reliable automatic V3250 caliber, this watch stands out for its sleek and refined silhouette. The black aventurine dial makes this model extremely distinctive. Completed with a tungsten bezel insert, resistant and scratch-proof, the 39mm Nereide offers a perfect balance between form and function.

High Accuracy
The V3250 caliber arrives at our laboratory, where it undergoes further regulation to improve its precision. The movement is adjusted to a range of -4/+6 seconds per day, achieving a very high level of performance, in line with haute horlogerie standards.
