Seiko 5 Sports U.S Special Creation. With vivid colors and bold design inspired by the stripes of vintage race cars, this dynamic watch delivers both memorable styling and durability. For added impact, the blue and white stripes flow from the dial to the coordinated nylon strap, sized to fit easily over a racing uniform. Framed by a blue uni-directional rotating bezel, the dial also offers a day/date calendar, yellow second hand, and luminous hands and markers. Providing automatic technology that you control with every movement, this memorable timepiece is powered by a 24-jewel movement that beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours and manual winding capability. The case, in stainless steel, includes a screwdown see-through caseback for a view of classic timekeeping in action. 10 bar, 100M Water Resistant
