Venezianico revisits its Nereide diver with the Nereide Opale Blu, a 600-piece edition defined by a Japanese lab-grown blue opal dial that turns light into shifting teal, azure and cobalt. Each dial is unique, not by marketing flourish but by the opal’s internal structure that scatters light differently every time.
The opal starts as a 0.4 mm sheet produced by KYOCERA®. It is fragile, so the brand progresses from cutting and drilling to polishing and hand-applied markers with patient restraint. The result is not paint on metal but colour born within matter. Composition is stated plainly: 80% silica and 20% resin.
The watch keeps the Nereide’s practical frame: a 42 mm 316L steel case with satin finish, sapphire crystal with anti-reflective coating, and a unidirectional bezel whose polished tungsten insert targets scratches with a Mohs 9 hardness. Water resistance is 20 atmospheres, and BGW9 Super-LumiNova® handles low light with cool-toned clarity.
Inside is the Swiss Made Sellita SW200-1 automatic movement, here given a little theater. Venezianico skeletonises and engraves the brass rotor, lays down radial Côtes de Genève with sunray satin at the edges, then rhodium plates it so light reads the geometry cleanly. Hidden parts deserve courtesy too.
The Sansovino bracelet completes the set, five links alternating satin and polish, with a tool-free micro-adjusting clasp for honest everyday sizing. Packaging echoes the dial’s play of light with an iridescent blue finish.
Details, in brief: 42 mm diameter, 49 mm lug-to-lug, 12.5 mm thickness. Bezel insert in tungsten. Sapphire crystal. BGW9 lume. 200 m water resistance. Limited to 600 pieces. The dial is lab-grown blue opal from Japan with teal, azure and cobalt reflections.
In an era of loud finishes, this piece chooses quiet depth. The opal does the speaking, the case keeps time, and the whole watch feels like Venice viewed beneath a moving sky.
