Seiko Prospex Collection Linited Edition Automatic & Manual Winding Watch With A Black Silicone Strap, 43.80mm, Stainless steel (hard coating) Case With Bezel & A Grey Coloured Dial With Date Window. DESCRIPTION Very popular since its inception and now in its third year of limited edition release, the Seiko Prospex Black Series was originally inspired by the mysterious world of night diving. The green lumibrite colouring on the markers and hands is designed for increased visibility in the dark world of the night seas, allowing time to be read clearly in dark conditions. This watch shape is nicknamed by Seiko fans as a ‘Samurai’ – because of its angular shaped design which looks as if it were sliced by a Japanese Samurai sword. Prospex is a combination of the words ‘Professional’ and ‘Specifications’. These timepieces are designed to be practical, reliable and durable within extreme or everyday environments, for experts, sports lovers and adventure seekers alike. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
