CASE MATERIAL: 316L Stainless Steel DIMENSIONS: Ø42 mm, lug to lug 49.00 mm MOVEMENT: Automatic Cal. Seiko NH35A CRYSTAL: Sapphire Glass with anti-reflective coating LUMINOUS MATERIAL: BGW9 Super-LumiNova® BEZEL: BK7 Crystal, 120 clicks WR: 20ATM (= 200mt) BRACELET: Canova 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. 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. The watch is brand new and comes with the correct retail packaging
