History
The 23-jewel Sportsmatic 5 Deluxe was released in May 1964 and was manufactured by Daini Seikosha. It represented an important chapter in Seiko's mid-century catalog, offering a reliable automatic movement alongside a clean, practical aesthetic. The hidden 4 o'clock crown became a signature design element of the era, emphasizing the convenience of the automatic winding system and creating a perfectly symmetrical case profile.
