There are just 1,200 pieces of this Limited Edition design available globally, commemorating the 35th anniversary of Seiko’s first 1,000m water resistant Saturation diver’s watch. Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. This watch has been created to acknowledge the harsh environments faced by Saturation divers – with higher legibility, even in deep waters as light and dark contrasts add clarity against its blue and black gradient dial (protected beneath sapphire crystal glass) inspired by the diver’s view of the depths. Its watch shape is affectionately nicknamed by Seiko fans as a ‘Tuna’ – because of its larger diameter and bold shape like a tuna tin – loved for decades since its release. The Seiko S23635J1 Prospex watch combines a 49.4mm round shaped ceramic, titanium and stainless steel case and a black silicone strap with a traditional buckle fastening. This timepiece comes with an additional silicone bracelet and Limited Edition box.
