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

Dans un classement id\u00e9al des meilleurs calibres de chronographe jamais r\u00e9alis\u00e9s, le mouvement 33.3, fabriqu\u00e9 par Lemania pour Omega, figure certainement en bonne place. Avec les 321 suivants et la famille d\u00e9riv\u00e9e du 861, le mouvement 33.3 repr\u00e9sente le summum de la qualit\u00e9 de fabrication \u00e0 la fin des ann\u00e9es 1930. Une caract\u00e9ristique qui le rend unique et facilement reconnaissable est, avant tout, l'inversion de la position du balancier et de son pont, contrairement \u00e0 tous les autres chronographes \u00e0 deux poussoirs fabriqu\u00e9s jusqu'alors. Le mouvement, dot\u00e9 d'une roue \u00e0 8 colonnes et d'un embrayage horizontal, s'inspire du Lemania 15CHT, qui a fait ses preuves (et qui \u00e9quipe \u00e9galement les chronographes de la marque Lemania). Le partenariat entre Omega et Lemania \u00e9tait cependant presque exclusif, commen\u00e7ant avec le 28.9CHRO (Lemania CH13 \u00e0 simple et double poussoir) et se poursuivant avec le 33.3CHRO (Lemania CH15) \u00e0 la fin des ann\u00e9es 1930.<\/span><\/p>\n

Il s'agit donc d'une rare beaut\u00e9 de la microm\u00e9canique, tr\u00e8s recherch\u00e9e par les collectionneurs.<\/span><\/p>\n

Cette Omega pr\u00e9sente d'autres caract\u00e9ristiques significatives qui en font une montre vraiment fascinante. Son cadran pr\u00e9sente une patine ocre chaude qui met en valeur les diff\u00e9rentes teintes des deux \u00e9chelles : l'\u00e9chelle tachym\u00e9trique bleue \u00e0 1000 bases, qui part du bord du cadran et s'enroule en spirale vers le centre, et l'\u00e9chelle t\u00e9l\u00e9m\u00e9trique rouge au c\u0153ur du cadran. Cette configuration est typique des Omega de cette p\u00e9riode. Cette pi\u00e8ce peut \u00eatre dat\u00e9e pr\u00e9cis\u00e9ment de 1941\/1942 sur la base du num\u00e9ro de s\u00e9rie figurant sur le pont d'\u00e9chappement. Les aiguilles sont tremp\u00e9es \u00e0 la flamme et pr\u00e9sentent un aspect r\u00e9tro classique.<\/span><\/p>\n

Le bo\u00eetier en acier Staybrite est \u00e9galement tr\u00e8s caract\u00e9ristique de cette production de chronographes Omega. Il pr\u00e9sente une structure circulaire tr\u00e8s nette et large ; il est beaucoup plus grand que la taille moyenne des chronographes d'autres marques de la fin des ann\u00e9es 1930 et du d\u00e9but des ann\u00e9es 1940. Avec un diam\u00e8tre de 37,5 mm, il pr\u00e9sente une allure tr\u00e8s moderne au poignet, notamment gr\u00e2ce \u00e0 ses belles cornes droites qui s'incurvent fortement. Sur le c\u00f4t\u00e9 droit se trouvent la belle couronne de remontoir d'origine et les poussoirs typiques en forme d'olive. Le fait d'avoir un grand bo\u00eetier avec une disposition de cadran qui maintient un lien direct avec le pass\u00e9 est la raison pour laquelle les collectionneurs aiment ces chronographes.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

Having a large case with a dial layout that maintains a direct link to the past is the reason why collectors love these chronographs.","og_url":"https:\/\/thevintageur.com\/fr\/boutique\/chronographe-omega-calibre-33-3\/","og_site_name":"The Vintageur","article_modified_time":"2025-08-13T12:41:44+00:00","og_image":[{"width":2560,"height":2560,"url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2015\/01\/2025-08-09-21-16-44-CS4.jpeg","type":"image\/jpeg"}],"twitter_card":"summary_large_image","twitter_misc":{"Prix":"7.500,00 €","Disponibilit\u00e9":"En stock"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/","url":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/","name":"Omega Chronographe avec \u00e9chelles tachym\u00e9trique et t\u00e9l\u00e9m\u00e9trique Bo\u00eetier en acier Staybrite Mouvement Omega 33.3 \u00e0 remontage manuel des ann\u00e9es 1940 - The Vintageur","isPartOf":{"@id":"https:\/\/thevintageur.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/#primaryimage"},"image":{"@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/#primaryimage"},"thumbnailUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2015\/01\/2025-08-09-21-16-44-CS4.jpeg","datePublished":"2025-08-10T10:44:47+00:00","dateModified":"2025-08-13T12:41:44+00:00","description":"SP\u00c9CIFICATIONS Rare chronographe Omega avec cadran bicolore \u00e0 double \u00e9chelle, bo\u00eetier en acier Staybrite de 37,5 mm et mouvement chronographe Omega 33.3 \u00e0 remontage manuel datant des ann\u00e9es 1940. Bo\u00eetier en acier Staybrite de 37,5 mm Verre en plastique d'origine Poussoirs en forme d'olive d'origine Couronne d'origine Mouvement de chronographe Omega 33.3 \u00e0 remontage manuel \u00e0 l'int\u00e9rieur ANALYSE Dans un classement id\u00e9al des meilleurs calibres de chronographe jamais r\u00e9alis\u00e9s, le mouvement 33.3, fabriqu\u00e9 par Lemania pour Omega, figure certainement en bonne place. Avec les 321 suivants et la famille d\u00e9riv\u00e9e du 861, le mouvement 33.3 repr\u00e9sente le summum de la qualit\u00e9 de fabrication \u00e0 la fin des ann\u00e9es 1930. Une caract\u00e9ristique qui le rend unique et facilement reconnaissable est, avant tout, l'inversion de la position du balancier et de son pont, contrairement \u00e0 tous les autres chronographes \u00e0 deux poussoirs fabriqu\u00e9s jusqu'alors. Le mouvement, dot\u00e9 d'une roue \u00e0 8 colonnes et d'un embrayage horizontal, s'inspire du Lemania 15CHT, qui a fait ses preuves (et qui \u00e9quipe \u00e9galement les chronographes de la marque Lemania). Le partenariat entre Omega et Lemania \u00e9tait toutefois presque exclusif, commen\u00e7ant avec le 28.9CHRO (Lemania CH13 \u00e0 simple et double poussoir) et se poursuivant avec le 33.3CHRO (Lemania CH15) \u00e0 la fin des ann\u00e9es 1930. Il s'agit donc d'une v\u00e9ritable beaut\u00e9 rare de l'ing\u00e9nierie microm\u00e9canique, tr\u00e8s recherch\u00e9e par les collectionneurs. Cette Omega pr\u00e9sente d'autres caract\u00e9ristiques significatives qui en font une montre vraiment fascinante. Son cadran pr\u00e9sente une patine ocre chaude qui met en valeur les diff\u00e9rentes teintes des deux \u00e9chelles : l'\u00e9chelle tachym\u00e9trique bleue \u00e0 1000 bases, qui commence sur le bord du cadran et s'enroule en spirale vers le centre, et l'\u00e9chelle t\u00e9l\u00e9m\u00e9trique rouge au c\u0153ur du cadran. Cette configuration est typique des Omega de cette p\u00e9riode. Cette pi\u00e8ce peut \u00eatre dat\u00e9e pr\u00e9cis\u00e9ment de 1941\/1942 sur la base du num\u00e9ro de s\u00e9rie figurant sur le pont d'\u00e9chappement. Les aiguilles sont tremp\u00e9es \u00e0 la flamme et pr\u00e9sentent un aspect r\u00e9tro classique. Le bo\u00eetier en acier Staybrite est \u00e9galement tr\u00e8s caract\u00e9ristique de cette production de chronographes Omega. Il pr\u00e9sente une structure circulaire tr\u00e8s nette et large ; il est beaucoup plus grand que la taille moyenne des chronographes d'autres marques de la fin des ann\u00e9es 1930 et du d\u00e9but des ann\u00e9es 1940. Avec un diam\u00e8tre de 37,5 mm, il pr\u00e9sente un aspect tr\u00e8s moderne au poignet, notamment gr\u00e2ce \u00e0 ses belles cornes droites qui s'incurvent fortement. Sur le c\u00f4t\u00e9 droit se trouvent la belle couronne de remontoir d'origine et les poussoirs typiques en forme d'olive. Le fait d'avoir un grand bo\u00eetier avec une disposition de cadran qui maintient un lien direct avec le pass\u00e9 est la raison pour laquelle les collectionneurs aiment ces chronographes.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2015\/01\/2025-08-09-21-16-44-CS4.jpeg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2015\/01\/2025-08-09-21-16-44-CS4.jpeg","width":2560,"height":2560},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/omega-chronograph-caliber-33-3\/#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 with Tachymeter and Telemeter Scales Staybrite Steel Case Manual-Wound Omega 33.3 Movement From the 1940s"}]},{"@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_amount":"7500.00","product_price_currency":"EUR","og_availability":"instock","product_availability":"instock","product_retailer_item_id":"467","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/1048","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=1048"}],"version-history":[{"count":0,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/1048\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media\/62279"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media?parent=1048"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_brand?post=1048"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_cat?post=1048"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_tag?post=1048"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
