At 3 o'clock is a dual window for the day and date.\u00a0 This dual complication in the 6139 movement conceals another interesting technical feature: the day\/date is a rapid-correct function activated by pressing the crown, which is hidden inside the side of the single-piece steel case. An intuitive and mechanically fascinating system. The hour and minute hands are pencil-shaped and feature a white luminescent coating; the minute hand and chronograph hand are a sporty orange. Completing this piece of all-time watchmaking history with a racing feel is a semi-integrated steel bracelet.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/seiko-chronograph-6139-8029-blue-eye-monobloc-steel-case-seiko-6139-automatic-chronograph-movement-from-the-70s-2\/#breadcrumb"},"inLanguage":"it-IT","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/seiko-chronograph-6139-8029-blue-eye-monobloc-steel-case-seiko-6139-automatic-chronograph-movement-from-the-70s-2\/"]}]},{"@type":"ImageObject","inLanguage":"it-IT","@id":"https:\/\/thevintageur.com\/shop\/seiko-chronograph-6139-8029-blue-eye-monobloc-steel-case-seiko-6139-automatic-chronograph-movement-from-the-70s-2\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/12\/seiko-6-iws.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/12\/seiko-6-iws.jpg","width":2560,"height":2560},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/seiko-chronograph-6139-8029-blue-eye-monobloc-steel-case-seiko-6139-automatic-chronograph-movement-from-the-70s-2\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/thevintageur.com\/"},{"@type":"ListItem","position":2,"name":"Shop","item":"https:\/\/thevintageur.com\/it\/negozio\/"},{"@type":"ListItem","position":3,"name":"Seiko Chronograph 6139-8029 &#8220;Blue Eye&#8221; Monobloc Steel Case Seiko 6139 Automatic Chronograph Movement From the 70s"}]},{"@type":"WebSite","@id":"https:\/\/thevintageur.com\/#website","url":"https:\/\/thevintageur.com\/","name":"Il Vintageur","description":"La vostra collezione di orologi su misura","publisher":{"@id":"https:\/\/thevintageur.com\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/thevintageur.com\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"it-IT"},{"@type":"Organization","@id":"https:\/\/thevintageur.com\/#organization","name":"Il Vintageur","url":"https:\/\/thevintageur.com\/","logo":{"@type":"ImageObject","inLanguage":"it-IT","@id":"https:\/\/thevintageur.com\/#\/schema\/logo\/image\/","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2023\/12\/logo-dark.svg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2023\/12\/logo-dark.svg","width":392,"height":28,"caption":"The Vintageur"},"image":{"@id":"https:\/\/thevintageur.com\/#\/schema\/logo\/image\/"},"sameAs":["https:\/\/www.instagram.com\/vintageur\/"]}]},"product_price_amount":"1200.00","product_price_currency":"EUR","og_availability":"instock","product_availability":"instock","product_retailer_item_id":"SEIKO CHRONO IWS","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product\/63126","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/comments?post=63126"}],"version-history":[{"count":2,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product\/63126\/revisions"}],"predecessor-version":[{"id":64165,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product\/63126\/revisions\/64165"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/media\/63132"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/media?parent=63126"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_brand?post=63126"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_cat?post=63126"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_tag?post=63126"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
