Seiko 5 Sports Field Watch HDB009

Authentic Field Style. Built to Perform.

The Seiko 5 Sports HDB009 is engineered for the field and styled for the outdoors. A rugged nylon strap combined with leather creates an authentic aesthetic that feels right at home in the field category, while a built-in compass adds real-world utility wherever the day takes you.

The rich brown dial brings a warm, earthy tone that pairs naturally with field and adventure fashion. Every numeral is coated with LumiBrite, Seiko's high-luminosity material, ensuring instant legibility in any lighting condition — from bright daylight to complete darkness.
