The Seiko Champion J15009 is a refined example of early 1960s Japanese watchmaking, produced by Daini Seikosha as the successor to the Cronos line. Designed to emphasize precision and thinness, the Champion series represents Seiko at an important moment in its mechanical evolution.
This watch features a 36.5mm stainless steel case, giving it a notably modern presence for a dress watch of its era. The silver dial shows attractive natural patina, accented by long, sharply cut hour markers, slim hands, and script branding with the Diashock 19 jewels signature. The overall design is clean, balanced, and unmistakably early 1960s Seiko.
It wears thin on the wrist with straight lugs and simple case lines. A newly fitted leather strap completes the look. The hand-wound movement is running at the time of listing and winds smoothly.
A timeless and understated vintage piece with strong design appeal and historical significance.
