It is driven by the highly regarded 26-jewel Caliber 6206 automatic movement, a premium workhorse engineered with an increased jewel count and Diashock protection to minimize drivetrain friction and deliver robust mechanical longevity.\u003c\/p\u003e\n\n\u003cp\u003eFollowing a full mechanical service, the caliber operates with optimal efficiency, providing the seamless automatic winding performance that established the line's prestige. The dial has been professionally redialed to a stunning blue color, complete with retro grid lines that create an incredible architectural backdrop. This vibrant blue canvas perfectly accentuates the unique, double-dot applied indices and sleek handset, catching light across the dial surface with sharp precision. Maintaining its iconic and highly symmetrical layout, it positions a cleanly framed date window at 3 o'clock and an independent, full-text horizontal day display above the 6 o'clock marker.\u003c\/p\u003e\n\n\u003cp\u003eThe stainless steel case is beautifully preserved, retaining its original factory geometry and the distinctively chunky, semi-square cushion silhouette that sits with excellent presence on the wrist. Emphasizing its pure automatic identity, the watch features a completely recessed crown at 4 o'clock, a signature Seikomatic engineering trait that ensures an unbroken, seamless case profile. The watch head remains highly authentic, retaining its original case, crystal, and hidden crown to meet the standards of discerning vintage enthusiasts. It comes paired with a premium brown leather strap with a lizard-skin texture.\u003c\/p\u003e\n\n\u003cp\u003eCollectors fiercely pursue the Seikomatic Weekdater for its historic full-text day complication and its rare, structural case variants. This 1966 specimen offers a perfect balance of mid-century design daring and mechanical vintage depth.\u003c\/p\u003e\n\n\u003cp\u003e💵 Price: $280 + $40 shipping (via USPS\/Singapore Post)\u003cbr\u003e\n💳 Payment via PayPal F\u0026amp;F or G\u0026amp;S, Payoneer or Wise\u003c\/p\u003e\n\n\u003cp\u003e#SeikoSeikomatic #SeikomaticWeekdater #VintageSeiko #Seiko6206 #BlueDial #RestoredDial #Weekdater #SplitCalendar #CushionCase #SeikoCollector #AvailableNow #hnvintagepieces\u003c\/p\u003e","brand":"HN Vintage Pieces","offers":[{"title":"Default Title","offer_id":50429849338049,"sku":"WATCH-112","price":280.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/7250\/0161\/files\/IMG_1627.jpg?v=1784808180","url":"https:\/\/hnvintagepieces.com\/products\/serviced-rare-vintage-1966-seiko-seikomatic-weekdater-blue-dial-26-jewels-6206-8120","provider":"HN Vintage Pieces","version":"1.0","type":"link"}
