ANALYSE<\/span><\/strong><\/p>\n

\u00c0 la fin des ann\u00e9es 1960, la grande maison japonaise a introduit l'un des mouvements \u00e0 remontage manuel les plus fins (seulement 8,7 mm d'\u00e9paisseur) qui oscillait \u00e0 36 000 vibrations par heure et garantissait des performances incroyables (certifi\u00e9es en interne par des tests tr\u00e8s rigoureux) dans toutes les conditions de position. Ce mouvement \u00e9tonnant \u00e9tait le 4520A et c'est pr\u00e9cis\u00e9ment ce calibre qui anime cette montre \u00e9tonnante.<\/span><\/p>\n

Le cadran est blanc avec des index b\u00e2tons appliqu\u00e9s en or avec insert noir. L'\u00e9criture Seiko \u00e0 12 heures et le logo de type GS \u00e0 6 heures sont \u00e9galement appliqu\u00e9s, ce qui conf\u00e8re une dimension tridimensionnelle \u00e0 l'ensemble du cadran. L'\u00e2me de cette montre exceptionnelle est affirm\u00e9e par l'\u00e9criture Hi-Beat 36000 en tampographie noire : une vitesse de l'aiguille des secondes qui conf\u00e8re \u00e0 la vue son mouvement v\u00e9ritablement continu et fluide. Aucune interruption. Les autres aiguilles des heures et des minutes sont en or en forme de b\u00e2ton et avec un insert noir pour donner une rapidit\u00e9 imm\u00e9diate \u00e0 la lecture de l'heure.<\/span><\/p>\n

Le bo\u00eetier de forme coussin en or jaune massif 18 carats est incroyablement travaill\u00e9 en surface avec un motif de lignes entrelac\u00e9es et obtenu avec une superbe technique de finition martel\u00e9e. Sur le c\u00f4t\u00e9 droit se trouve la magnifique couronne orn\u00e9e d'un logo. Sur le fond ext\u00e9rieur du bo\u00eetier, 6 encoches indiquent que la fermeture \u00e0 vis garantit une \u00e9tanch\u00e9it\u00e9 suffisante. Au centre, la belle gravure sur l'or jaune Seiko GS. Pour finir ce chef-d'\u0153uvre, il y a la boucle dor\u00e9e originale avec le logo.<\/span><\/p>\n

Sur le fond ext\u00e9rieur du bo\u00eetier, 6 encoches indiquent que la fermeture \u00e0 vis garantit une \u00e9tanch\u00e9it\u00e9 suffisante. Au centre, la belle gravure sur l'or jaune Seiko GS. Pour terminer ce chef-d'\u0153uvre, il y a la boucle originale en or avec le logo. Une montre incroyable qui est un concentr\u00e9 de d\u00e9tails esth\u00e9tiques et techniques de la plus haute horlogerie japonaise et qui en fait l'un des plus grands chefs-d'\u0153uvre de Grand Seiko.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/grand-seiko-hi-beat-ref-4520-8010-solid-18k-yellow-gold-from-70s\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/grand-seiko-hi-beat-ref-4520-8010-solid-18k-yellow-gold-from-70s\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/thevintageur.com\/shop\/grand-seiko-hi-beat-ref-4520-8010-solid-18k-yellow-gold-from-70s\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF8131.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF8131.jpg","width":2560,"height":2560},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/grand-seiko-hi-beat-ref-4520-8010-solid-18k-yellow-gold-from-70s\/#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":"GRAND SEIKO HI BEAT REF 4520-8010 SOLID 18K YELLOW GOLD FROM 70S"}]},{"@type":"WebSite","@id":"https:\/\/thevintageur.com\/#website","url":"https:\/\/thevintageur.com\/","name":"Le Vintageur","description":"Votre collection de montres sur mesure","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":"fr-FR"},{"@type":"Organization","@id":"https:\/\/thevintageur.com\/#organization","name":"Le Vintageur","url":"https:\/\/thevintageur.com\/","logo":{"@type":"ImageObject","inLanguage":"fr-FR","@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_currency":"EUR","og_availability":"out of stock","product_availability":"out of stock","product_retailer_item_id":"755","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/50447","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/comments?post=50447"}],"version-history":[{"count":1,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/50447\/revisions"}],"predecessor-version":[{"id":63167,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/50447\/revisions\/63167"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media\/50449"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media?parent=50447"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_brand?post=50447"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_cat?post=50447"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_tag?post=50447"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
