Authentic Field Style. Built to Perform.There's a reason the field watch with a fabric strap has endured as one of the most iconic watch configurations in history — it's light, comfortable, and looks exactly right in the outdoors. The Seiko 5 Sports HDB008 captures that spirit completely with a nylon-and-leather strap that delivers an authentic field aesthetic and a noticeably lighter wear than the bracelet models, while a built-in compass bezel adds real-world utility wherever the day takes you.The khaki green dial is the natural choice for a field watch — an earthy, outdoor-ready tone that pairs naturally with field and adventure fashion and feels genuinely at home in the category. Every numeral is coated with LumiBrite, Seiko's high-luminosity material, ensuring instant legibility from bright daylight to complete darkness. The Caliber 4R36 automatic movement with manual winding and stop-second function keeps running as long as you do, with 10 bar (100m) water resistance and 4,800 A/m magnetic resistance for genuine field capability.Light on the wrist.
