Seiko 5 Sports Field Series HUF Limited Edition SRPM09K1J

Seiko 5 Sports Field Series HUF Limited Edition SRPM09K1J.

Limited edition of 7,000 pieces
Seiko 5 Sports introduces a limited-edition collaboration model with HUF. Based on an archival Seiko model from the 1970s, affectionately known as the “Time Sonar,”
this special timepiece has been reimagined with HUF’s unique style and finished with exclusive design elements.

Founded in 2002 by professional skateboarder Keith Hufnagel, HUF is a lifestyle brand rooted in the spirit of skateboarding and street culture.
Originally launched as a shop with a curated mix of brands, HUF evolved into a full-fledged label expressing its founder’s vision of skateboarding and street culture. Today, HUF has grown into a highly respected lifestyle brand, earning recognition across a wide range of fields.

Since its founding, HUF has advanced the innovative vision of Keith Hufnagel, consistently delivering a clean aesthetic, bold design, and high-quality craftsmanship. 

The semi-transparent dial features the vibrant “HUF Green,” a color that symbolizes HUF’s philosophy. This exclusive colorway did not exist on the original archival model, making it a unique expression created specifically for this collaboration.
The ”huf” logo is placed at the 6 o’clock position on the dial. 

The exhibition case back features the same “HUF Green” as the dial and is decorated with a graphic inspired by San Francisco, the city where HUF was founded. As a mark of exclusivity, “LIMITED EDITION” and an individual serial number are engraved on the case back.
