New release Seiko Prospex special edition automatic has been designed in collaboration with ocean explorer and marine conservationist Faiben Costeau. The Stainless Steel case is 42.6mm with a 120-click undirectional rotating bezel. The SPB071J1 includes LumiBrite hour markers and hands, with a fine metallic border that sits nicely on the Save the Ocean style blue graduated degrade dial with Whale skin style ridges, for easy reading in low-light conditions. Powered by a Japanese 6R15 automatic movement with manual wind ability, this timepiece has an impressive power reserve of approximately 40 hours. The SPB071J1 also has a day/date function at 3 o'clock through a beveled window. With the Prospex range being built to sustain harsh conditions, the screw down stainless steel case back gives the watch a water resistance up to 200m with Seiko's hardened mineral glass offering excellent legibility. Set upon a blue silicone strap and fastened with a classic buckle it gives a soft and flexible fit. SRPD09K1 comes complete with a two year guarantee and an official Limited Edition Save The Ocean Seiko watch presentation box.
