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

Questo eccezionale orologio Omega segna l'inizio dell'avventura pionieristica che ha portato allo sviluppo dei cronografi da polso tra la fine degli anni Venti e l'inizio degli anni Trenta.<\/span><\/p>\n

Questo splendido orologio presenta un quadrante smaltato di qualit\u00e0 museale con indici arabi in stile Breguet. L'intero perimetro del quadrante \u00e8 occupato da una scala tachimetrica a cinque spirali di colori diversi. Gli stessi cinque colori sono utilizzati anche sul quadrante dei minuti cronografici, per una visione immediata della velocit\u00e0. Questo quadrante a settori multicolori \u00e8 stato brevettato in Francia nel 1902. L'iscrizione a ore 6, \"Cadran Brevet\u00e9 S.G.D.G\", fa riferimento a quel brevetto.<\/span><\/p>\n

L'acronimo \"S.G.D.G.\" Tradotto letteralmente in francese come \"Brevet\u00e9 Sans Garantie Du Gouvernement\", i governi francese e belga si sono esentati dalla responsabilit\u00e0 di garantire la funzionalit\u00e0 dell'invenzione. La firma e il logo Omega si trovano a ore 12, mentre le lancette in stile Breguet, abbinate agli indici, sono tradizionalmente temperate in blu.<\/span><\/p>\n

La grande e solida cassa in oro giallo 18 carati \u00e8 in tre pezzi e presenta anse inclinate e il pulsante di avvio, arresto e azzeramento del meccanismo cronografico a ore 6 sulla carrure. La bella corona sovradimensionata a \"cipolla schiacciata\" spicca sul lato posteriore.<\/span><\/p>\n

Sotto il fondello incernierato, ovviamente firmato da Omega all'interno, si nasconde il capolavoro: il calibro cronografico in-house 18\u2033 CHRO. Macchina eccezionale, rappresenta un capitolo fondamentale nella storia dell'orologeria. \u00c8 infatti il primo cornografo della storia a essere prodotto in serie: ha un meccanismo orizzontale e una ruota a colonne; ha uno scappamento a leva; ha 15 rubini e una spirale Breguet; batte a 18.000 alternanze l'ora.<\/span><\/p>\n

Un orologio davvero eccezionale per rarit\u00e0, condizioni, caratteristiche storiche e tecniche. Una vera favola romantica da portare al polso.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

This splendid watch features a museum-quality enamel dial with Breguet-style Arabic hour markers. The entire perimeter of the dial is occupied by a five-spiral tachymeter scale in different colors. The same five colors are also used on the chronograph minute subdial, allowing for an immediate view of speeds. This multi-color sector dial was patented in France in 1902.

Macchina eccezionale, rappresenta un capitolo fondamentale nella storia dell'orologeria. \u00c8 infatti il primo cornografo della storia a essere prodotto in serie: ha un meccanismo orizzontale e una ruota a colonne; ha uno scappamento a leva; ha 15 rubini e una spirale Breguet; batte a 18.000 alternanze l'ora. Un orologio davvero eccezionale per rarit\u00e0, condizioni e caratteristiche storiche e tecniche. Una vera favola romantica da portare al polso.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/omega-big-chrono-aviator-ot-741-as\/#breadcrumb"},"inLanguage":"it-IT","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/omega-big-chrono-aviator-ot-741-as\/"]}]},{"@type":"ImageObject","inLanguage":"it-IT","@id":"https:\/\/thevintageur.com\/shop\/omega-big-chrono-aviator-ot-741-as\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2016\/11\/PB173181-scaled.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2016\/11\/PB173181-scaled.jpg","width":2560,"height":2560,"caption":"OLYMPUS DIGITAL CAMERA"},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/omega-big-chrono-aviator-ot-741-as\/#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":"Omega Chronograph “Cadran Brevet\u00e9 S.G.D.G.” 18KT Yellow Gold Case Manual-Wound Omega Movement 18″ CHRO From the 1930s"}]},{"@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_currency":"EUR","og_availability":"instock","product_availability":"instock","product_retailer_item_id":"51","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product\/820","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=820"}],"version-history":[{"count":0,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product\/820\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/media\/5985"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/media?parent=820"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_brand?post=820"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_cat?post=820"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/it\/wp-json\/wp\/v2\/product_tag?post=820"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
