This serviced 1960s Seiko Sportsmatic 5 represents mid-1960s Japanese horology, capturing the foundational design of the legendary Seiko 5 series. It is powered by the robust 21-jewel Caliber 6619 automatic movement from Suwa Seikosha, featuring Diashock shock protection and semi-quickset date operation. Freshly serviced and regulated, it operates with minimal daily deviation, strong winding efficiency, and dependable performance.
The watch features a factory-original silvery-white sunburst dial with a crisp radial brushed texture. The layout is appointed with an applied silver SEIKO logo, the iconic "5" shield emblem, cursive Sportsmatic typography, and "WATER PROOF DIASHOCK 21 JEWELS" script. Faceted baton markers and razor-sharp dauphine hands frame a clean calendar window at 3 o'clock showcasing a desirable domestic Kanji day display.
The 36mm stainless steel case preserves clean factory curves, polished bezel surfaces, and contoured lugs that wear comfortably on the wrist. True to signature Sportsmatic architecture, it features a flush-recessed crown at 4 o'clock for a sleek silhouette. The watch head is 100% authentic and unaltered, retaining its original dial, hands, crystal, case, and recessed crown. It comes paired with a premium textured black leather strap.
An exceptional 1960s Sportsmatic 5 reference combining historic Caliber 6619 engineering, the genesis of the Seiko 5 lineage, an authentic domestic Kanji calendar, and untouched factory-original preservation.
