Seiko 5 Sports HUF Limited Edition SRPM09

A Bold Collaboration Between Heritage and Street Culture

Seiko 5 Sports introduces a limited-edition collaboration with HUF, inspired by a 1970s archival Seiko model affectionately known as the “Time Sonar.”

This special edition reimagines the vintage classic through HUF’s unmistakable street-driven aesthetic, finished with exclusive design details created specifically for this partnership.
