Dimensions The case measures 36mm in diameter (excluding the crown). Remarks This Sportsmatic 5 offers an exceptionally clean dial combined with the charm of a Kanji day wheel. It represents an accessible and authentic entry into 1960s Japanese horology with a robust in-house caliber. History Introduced in 1964, the same year as the Tokyo Olympic Summer Games, the Seiko caliber 6619A is a self-winding movement that helped establish the enduring legacy of the Seiko 5 line. Designed without manual winding or hacking capabilities, the movement relies entirely on the efficiency of its automatic winding system. Interestingly, the 21-jewel 6619A includes three non-functional blind jewels on the dial side, a distinctive period addition likely intended to elevate its market positioning above standard 17-jewel calibers of the era. The Sportsmatic 5 remains a fundamental model in mid-century Japanese watchmaking. Payment and Shipping Payment must be completed within 1–3 days after purchase.
