A tribute to the 70s-era 'Time Sonar' with a modern, streetwear twist

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, most notably a semi-transparent dial featuring the vibrant “HUF Green” (a color not found on the original archival model), and an exhibition caseback featuring the same color as the dial. It's 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 caseback.

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.
