Seiko Sportsmatic 5 Water Proof Day Date Automatic

Vintage Seiko Sportsmatic 5 automatic featuring a clean silver dial, applied baton indices, and bilingual day date display. This model carries the classic early Seiko Sportsmatic styling with a balanced dial layout, sharp handset, and stainless steel bracelet that gives it a distinctly 1960s executive aesthetic. Powered by a 21 jewel Diashock automatic movement, the Sportsmatic line helped establish Seiko’s reputation for durable and reliable everyday automatics during the golden age of Japanese watchmaking. The subtle patina and honest wear add character without overwhelming the watch’s clean appearance. Mechanical engineering from an era when “water proof” was casually printed on dials and lawyers had not yet evolved into their final corporate forms.
