A tribute to the archival 1970s “Time Sonar” model. The huf® x Seiko 5 Sports: SRPM09 introduces the vibrant “huf® Green” colorway, exclusive to the collaboration, which accents the semi‑transparent dial and highlights the mechanical movement beneath.

Housed in a robust stainless steel case with a matching bracelet, the exhibition case-back is etched with the huf® logo in its signature green. To further distinguish the piece, the seconds hand is also painted in the same huf® green, providing a high-contrast tick against the dark, smoky background of the dial.
