Nereide Opale Blu - Limited Edition
Shipments begin on September 15th
Our research into materials has led us to explore lab-grown opal, a gemstone with a complex structure capable of creating a unique character in every dial. In this interpretation, the opal takes on a distinctive monochromatic blue tone that, as the light changes, reveals a rich spectrum of teal, azure and cobalt reflections, creating a surface in constant transformation. The complexity of the manufacturing process and the time required to produce each dial naturally limit production. Each piece features a one-of-a-kind pattern, making every Nereide Opale Blu truly unique.

The lab-grown opal used for Nereide is created in the KYOCERA® laboratories in Japan, the only facility in the world to produce this material through a proprietary process. The formation of its structure requires extended growth periods and extremely rigorous control, resulting in a surface of extraordinary optical depth. The limited availability of the material means that we work exclusively with small batches, reserved for highly limited production runs.

Each dial is crafted from a sheet of lab-grown opal just 0.4 mm thick. Despite its exceptional hardness, the material is extremely fragile and requires a gradual, carefully controlled approach at every stage of production. From cutting and drilling to polishing and the hand-application of the indices, every step is carried out in-house using dedicated tools and a level of precision refined through experience.

Our rotor
Fitted to the Swiss Made Sellita SW200-1 automatic calibre, our rotor is crafted from a brass base, which is subsequently skeletonised and engraved. Its surface is finished with a radial Côtes de Genève decoration and soleil brushing on the outer sections, before being completed with rhodium plating, which gives it its distinctive silver-toned finish and enhances every detail of the craftsmanship.
Technical Specifications
Our dive watch, water-resistant to a depth of 200 meters, takes its name from the Nereide submarine, a marvel of Venetian naval technology. This timepiece is engineered to endure strong stresses, making it particularly well-suited for water sports enthusiasts.
