Powered by the workhorse 21-jewel Caliber 6619 automatic movement, this early Diashock model was engineered to deliver the \"five\" core attributes - automatic winding, day-date display, water resistance, recessed crown, and durability - that revolutionized the concept of the everyday sport-dress watch.\u003cbr\u003eRecently serviced, the timepiece provides smooth mechanical performance and remains a reliable companion for daily wear. While the quick-set date (push-button) function is currently bypassable and requires manual setting through the hands, the movement otherwise keeps excellent time. The silver sunburst dial is in 100% original condition, featuring the early-style applied '5' shield and sharp, faceted indices that catch the light with classic 1960s brilliance. The dial's layout, including the framed day-date complication, remains crisp and serves as a beautifully preserved example of Seiko's mid-century design language.\u003cbr\u003eThe stainless steel case retains its original factory geometry, showcasing the distinctive unpolished lug lines and the iconic recessed crown at 4 o'clock. While the case bears the honest, marks of a life lived since 1964, it maintains a strong presence on the wrist and preserves the authentic vintage character prized by collectors. The watch head is entirely factory-correct, with the original dial, crystal, and case ensuring its historical integrity. To refresh its classic look, it has been paired with a high-quality replacement strap that perfectly balances its rugged yet elegant aesthetic.\u003cbr\u003eCollectors highly value these first-generation Sportsmatic 5 models for their role as the foundation of Seiko’s most enduring legacy. This 1964 specimen offers a superb combination of mechanical heritage and timeless style - a compelling and historically significant addition to any vintage Seiko collection.\u003c\/p\u003e","brand":"HN Vintage Pieces","offers":[{"title":"Default Title","offer_id":50259827949761,"sku":"SEIKO-1964-0055","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/7250\/0161\/files\/IMG_9018.jpg?v=1779727893","url":"https:\/\/hnvintagepieces.com\/products\/serviced-rare-vintage-1964-seiko-sportsmatic-5-diashock-21-jewels-6619-7990","provider":"HN Vintage Pieces","version":"1.0","type":"link"}
