Apart of the Seiko Prospex ‘Black Series’ collection, comes the new release of this ‘Night Vision’ Sumo Limited Edition watch. Magnificently constructed to depict the views seen when diving at night, this model only has 3,500 pieces available worldwide. This timepiece features a textured black dial, with a sophisticated all-black stainless-steel case and bracelet. For added visibility the hands and indexes are coated with a high grade vibrant green lumibrite pro. The models in this new ‘Night Vision’ series are the first of the Seiko watches to feature such a coloured lumibrite pro for ease of visibility in the dark, having a higher level of intensity ensuring it glows brighter and longer. In the classic Prospex ‘Sumo’ style, this model features a mechanical automatic 6R35 movement with the added astounding accuracy tolerance of 25 -15 seconds a day. The elegant and sophisticated design of the watch combined with the flush functionality of the piece is beautifully seamless. - Limited Edition- Automatic Movement (Power by the movement of the wearer) - Accuracy: 25 -15 seconds a DAY (at normal temperature range (5°C and 35°C)- Cal. 6R35- 70 Hours Power Reserve- 45mm Case Size- 13mm Thickness- 190g Weight- Stainless Steel Case and Bracelet - Sapphire Glass with Anti-Reflective Coating on the Inside- Screw Back Case - Screw Down Crown - Rotating Bezel One Way (Ceramic)- Three-fold clasp w/ secure lock, push button release with extender- Hand Winding Capability- 200 Meters Water Resistant (Divers)
