A bold collaboration between Seiko and HUF brings new life to a beloved 1970s Seiko design known among collectors as the “Time Sonar.” This modern reinterpretation blends the archival spirit of the original with HUF’s unmistakable street‑driven aesthetic, resulting in a timepiece that feels both nostalgic and refreshingly contemporary.
HUF: From Skate Shop to Global Icon
HUF was established in 2002 by professional skateboarder Keith Hufnagel, whose vision was deeply rooted in the raw energy of skateboarding and street culture. What began as a boutique retail space showcasing a curated selection of brands quickly evolved into a full-fledged lifestyle label. Today, HUF stands as a respected global name, recognized for its clean design language, bold creative direction, and commitment to quality craftsmanship—values that continue to reflect Hufnagel’s legacy.
A Field Watch Reimagined in “HUF Green”
This limited-edition model is built on the Seiko 5 Sports Field platform and distinguished by its signature “HUF Green” colorway. The semi‑transparent dial—an homage to the original Time Sonar—glows with this vibrant shade, a hue created exclusively for the collaboration and never seen on the vintage model. The “huf” logo sits subtly at 6 o’clock, anchoring the design with understated confidence.
Exclusive Case Back Design
The exhibition case back mirrors the dial’s striking green tone and features artwork inspired by San Francisco, the birthplace of HUF. Each piece is individually numbered and engraved with “LIMITED EDITION,” underscoring its collectible nature.
Special Presentation
The watch arrives in a custom stainless steel box and includes an original HUF-branded cleaning cloth—finishing touches that elevate the entire experience.
