The name of the watch is a tribute to the Venetian submarine called Nereide which was built in the Royal Arsenale in 1913 and commissioned to the engineer De Bernardis by the Royal Navy during the First World War. The timepiece recalls the design of WWI submarines and bears a pressure of 20 atmospheres.

 

We have reinterpreted one of the most appreciated bracelets in the world of watchmaking, perfectly adapting shapes and finishes to the Nereide case. We made several tests to obtain a high quality and ergonomic product with a double brushed and polished finish. A perfect fit on the wrist is guaranteed. In fact, this bracelet is equipped with a butterfly clasp which offers an extremely comfortable fit.

 

BK7 Crystal Bezel Insert

 

The BK7 Crystal has exceptional physical properties, is lead-free, relatively lighter and of higher quality than other glass crystals. Its properties are: low dispersion (with Abbe numbers around 60), the low refractive index (≈1.52) and high clarity. For these reasons, after a long research and development process, we decided to produce the new inserts with Nereide bezel in this material.

 

Deep satin finish

 

This careful stylistic choice provides a more modern look to a design that aims to convey tradition and innovation at the same time. The deep satin finish is obtained through the use of special brushes by skilled craftsmen who finish each individual surface through a completely manual process. Several handmade steps are required to achieve a homogeneous result that passes the internal quality control process.

 

BGW9 Super-LumiNova®

 

Swiss Super-LumiNova® BGW9 is a phosphorescent pigment, otherwise known as Lume, emits a Blue-Green glow in the dark (as the name suggest) when properly charged by either sunlight or artificial light. In a daylight condition, BGW9 is white in color.
Compared to the much more widespread C1 pigment, the BGW9 has a relative brightness more than triple, making it the most widespread solution in the haute horlogerie.

 

A case-back engraved with a story of heroes

 

Nereide’s hull, like that of her sister ship Nautilus, was shaped similar to a torpedo boat, designed by the well-known Curio Bernardis. Nereide was a Nautilus-class submarine in the Italian Royal Navy (Italian: Règia Marina) during World War I. It was built 1911–1913 at the navy yard at Venice and was sunk in 1915 by the Austro-Hungarian submarine U-5 under the command of Georg Ritter von Trapp.
