SEIKO 5 Sports Field HDB009K1 - Men's Brown Dial Automatic Compass Watch

The Seiko 5 Sports Field HDB009K1 brings an earthy, outdoor-ready take to the refreshed Field series. Its glossy brown dial pairs with a matching bi-directional rotating compass bezel, giving the watch genuine navigational function alongside its rugged aesthetic. Every Arabic numeral hour marker, the hands, and the bezel's North indicator are coated in Seiko's LumiBrite for excellent legibility in low light or under forest canopy. Rounding out the field-ready look is a durable nylon strap combined with leather detailing, chosen specifically for authenticity and outdoor durability.

Driving the watch is Seiko's Caliber 4R36, an in-house automatic movement with manual winding capability, running at 21,600 vph across 24 jewels. It delivers a day/date display and a stop-second hand (hacking) function, letting you freeze the seconds hand for precise time-setting, backed by approximately 41 hours of power reserve. The stainless steel case measures 41.0mm in diameter and 13.2mm thick, with a 48.5mm lug-to-lug span for a balanced, comfortable fit. A curved Hardlex crystal shields the dial from scratches and glare.

Built for daily wear and outdoor adventures, the HDB009K1 carries a 10 bar (100m) water resistance rating and 4,800 A/m magnetic resistance. A see-through screw case back provides a view of the automatic movement in motion. Thanks to its nylon-and-leather strap construction, the watch comes in notably lighter than its bracelet-equipped siblings, weighing just 85.0g - making it especially comfortable for all-day and all-wrist-size wear.
