History Introduced in the early 1960s, the Sportsmatic line played a crucial role in establishing Seiko's reputation for producing robust, reliable automatic timepieces. The 5 designation was created to highlight key attributes, including an automatic movement, a day and date display, and a durable case design. The presence of Water 30 Proof on the dial is a distinctive characteristic of early 1960s production, utilized before international nomenclature shifted away from proof terminology later in the decade. / Second Vintage SKU: SEI-SSW-0001
