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

Il s'agit d'une montre sp\u00e9ciale. Une combinaison de savoir-faire qui fait de cette pi\u00e8ce un v\u00e9ritable chef-d'\u0153uvre extr\u00eamement rare. Le d\u00e9but des ann\u00e9es 1950 a vu une \u00e9volution du go\u00fbt et du design : les artistes se lib\u00e9raient du fardeau de la trag\u00e9die de la Seconde Guerre mondiale et s'ouvraient \u00e0 l'exploration de nouveaux concepts esth\u00e9tiques. Cette extraordinaire Omega est un exemple concret de cette \u00e9volution.<\/span><\/p>\n

Le cadran en or est un exemple de savoir-faire artisanal. Sa surface est guilloch\u00e9e \u00e0 l'ext\u00e9rieur. Un cadre interne tr\u00e8s fin le s\u00e9pare du centre du cadran, qui est trait\u00e9 avec de d\u00e9licates rainures en lignes verticales parall\u00e8les. Au centre du cadran, \u00e0 12 heures, une section rectangulaire en relief porte la signature et le logo Omega. Les index appliqu\u00e9s contribuent \u00e0 l'imagination de la disposition : ils ont la forme de doubles diamants ; plus \u00e0 l'int\u00e9rieur, \u00e0 12, 3 et 9 heures, se trouvent d'\u00e9tonnants index \u00e0 base circulaire qui s'\u00e9l\u00e8vent comme trois petites pyramides scintillantes. Ce magnifique cadran est compl\u00e9t\u00e9 par des aiguilles douphine tr\u00e8s fines et une surface \u00e0 double pente.<\/span><\/p>\n

Le bo\u00eetier en or rose massif 18 carats avec cornes \"hood\" est un chef-d'\u0153uvre du ma\u00eetre genevois Antoine Gerlach, actif des ann\u00e9es 1930 aux ann\u00e9es 1970 (poin\u00e7on cl\u00e9 : \"4\"). C'est cet artiste qui, \u00e0 partir de 1932, a cr\u00e9\u00e9 certains des bo\u00eetiers les plus beaux et les plus embl\u00e9matiques de Patek Philippe. Il a r\u00e9alis\u00e9 le bo\u00eetier en or embl\u00e9matique de la Calatrava 96R (1941) et celui du quanti\u00e8me perp\u00e9tuel \"Disco Volante\" 3448 (d\u00e9but des ann\u00e9es 1970). Gerlach a \u00e9galement beaucoup collabor\u00e9 avec Omega. Il a con\u00e7u et produit les bo\u00eetiers des Constellation avec des cadrans pie-pan \"immatures\" (ou \"pseudo-pie-pan\") entre les ann\u00e9es 1950 et 1960. Bref, un grand ma\u00eetre-\u00e9tuyer qui a cr\u00e9\u00e9 certaines des montres les plus embl\u00e9matiques de tous les temps \u00e0 Gen\u00e8ve.<\/span><\/p>\n

Ce splendide bo\u00eetier est assorti d'un tout aussi splendide bracelet construit avec des intervalles de quatre et trois tr\u00e8s petits maillons souples. Il se termine par un fermoir r\u00e9glable qui assure confort et s\u00e9curit\u00e9 au poignet.<\/span><\/p>\n

Sous le fond pr\u00e9cieux et r\u00e9fl\u00e9chi de cette montre se trouve le calibre automatique Omega 342. Il est entr\u00e9 en production en 1949 et a redessin\u00e9 le calibre 340 datant de quelques mois afin d'am\u00e9liorer sa fonction de remontage. L'Omega 342 mesure 28,5 mm de large et 4,8 mm d'\u00e9paisseur ; il poss\u00e8de 17 rubis, une r\u00e9serve de marche de 42 heures et une fr\u00e9quence de 19 800 tours par minute.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

A combination of craftsmanship that makes this piece a truly and extremely rare masterpiece. The early 1950s saw an evolution in taste and design: artists were freeing themselves from the burden of the tragedy of World War II and were opening themselves to the exploration of new aesthetic concepts. This extraordinary Omega is a concrete example of this evolution. The gold dial is a display of craftsmanship. Its surface features a guilloche-decorated exterior. A very thin internal frame separates it from the center of the dial, which is treated with delicate grooves in parallel vertical lines. At the center of the dial, at 12 o'clock, is a rectangular raised section featuring the Omega signature and logo. The applied indexes contribute to this imaginative flair of the layout: they are shaped like double diamonds; further inward, at 12, 3, and 9 o'clock, are stunning circular-based indexes that rise like three small, shimmering pyramids. This magnificent dial is finished with razor-sharp douphine hands and a double-sloped surface. The solid 18K rose gold case with "hood" lugs is a masterpiece by Genevan master Antoine Gerlach, active from the 1930s to the 1970s (key hallmark: "4"). He is the artist who, starting in 1932, created some of Patek Philippe's most beautiful and iconic cases. He crafted the iconic gold case of the Calatrava 96R (1941) and that of the "Disco Volante" perpetual calendar 3448 (early 1970s). Gerlach also collaborated extensively with Omega. He designed and produced the Constellation cases with "immature" pie-pan dials (or "pseudo-pie-pan" dials) between the 1950s and 1960s. In short, a great master casemaker, who created some of the most iconic watches of all time in Geneva. This splendid case is paired with an equally splendid bracelet constructed with intervals of four and three very small, soft links. It ends in an adjustable clasp to ensure comfort and security on the wrist. Beneath the precious and thoughtful caseback of this watch is the Omega 342 automatic bumper caliber. It went into production in 1949 and redesigned the caliber 340 from a few months earlier to improve its winding function.

He is the artist who, starting in 1932, created some of Patek Philippe's most beautiful and iconic cases. He crafted the iconic gold case of the Calatrava 96R (1941) and that of the \"Disco Volante\" perpetual calendar 3448 (early 1970s). Gerlach also collaborated extensively with Omega. He designed and produced the Constellation cases with \"immature\" pie-pan dials (or \"pseudo-pie-pan\" dials) between the 1950s and 1960s. In short, a great master casemaker, who created some of the most iconic watches of all time in Geneva. This splendid case is paired with an equally splendid bracelet constructed with intervals of four and three very small, soft links. It ends in an adjustable clasp to ensure comfort and security on the wrist. Beneath the precious and thoughtful caseback of this watch is the Omega 342 automatic bumper caliber. It went into production in 1949 and redesigned the caliber 340 from a few months earlier to improve its winding function. The Omega 342 is 28.5mm wide and 4.8mm thick; it has 17 jewels, a 42-hour power reserve, and a frequency of 19,800 vph.","og_url":"https:\/\/thevintageur.com\/fr\/boutique\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-1950s\/","og_site_name":"The Vintageur","article_modified_time":"2026-06-03T13:06:20+00:00","og_image":[{"width":960,"height":960,"url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/09\/OMEGA-AUTOMATIC-_GERLACH_-18KT-ROSE-GOLD_1_1-960x960.jpg","type":"image\/jpeg"}],"twitter_card":"summary_large_image","twitter_misc":{"Prix":"","Disponibilit\u00e9":"En stock"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/","url":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/","name":"Omega Automatic \"Gerlach\" 18KT Rose Gold Case In-House Self-Winding Movement 342 From 1950s - The Vintageur","isPartOf":{"@id":"https:\/\/thevintageur.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/#primaryimage"},"image":{"@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/#primaryimage"},"thumbnailUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/09\/OMEGA-AUTOMATIC-_GERLACH_-18KT-ROSE-GOLD_1_1.jpg","datePublished":"2026-06-03T08:41:29+00:00","dateModified":"2026-06-03T13:06:20+00:00","description":"SP\u00c9CIFICATIONS Rarissime Omega Automatique avec bo\u00eetier en or rose 18 carats con\u00e7u et produit par Antoine Gerlach, cadran guilloch\u00e9 en or rose, bracelet en or rose, mouvement \u00e0 remontage automatique Omega 342 \u00e0 l'int\u00e9rieur, datant du d\u00e9but des ann\u00e9es 1950.

Une combinaison de savoir-faire qui fait de cette pi\u00e8ce un v\u00e9ritable chef-d'\u0153uvre extr\u00eamement rare. Le d\u00e9but des ann\u00e9es 1950 a vu une \u00e9volution du go\u00fbt et du design : les artistes se lib\u00e9raient du fardeau de la trag\u00e9die de la Seconde Guerre mondiale et s'ouvraient \u00e0 l'exploration de nouveaux concepts esth\u00e9tiques. Cette extraordinaire Omega est un exemple concret de cette \u00e9volution. Le cadran en or est un exemple de savoir-faire. Sa surface est guilloch\u00e9e \u00e0 l'ext\u00e9rieur. Un cadre interne tr\u00e8s fin le s\u00e9pare du centre du cadran, qui est trait\u00e9 avec de d\u00e9licates rainures en lignes verticales parall\u00e8les. Au centre du cadran, \u00e0 12 heures, une section rectangulaire en relief porte la signature et le logo Omega. Les index appliqu\u00e9s contribuent \u00e0 l'imagination de la disposition : ils ont la forme de doubles diamants ; plus \u00e0 l'int\u00e9rieur, \u00e0 12, 3 et 9 heures, se trouvent d'\u00e9tonnants index \u00e0 base circulaire qui s'\u00e9l\u00e8vent comme trois petites pyramides scintillantes. Ce magnifique cadran est compl\u00e9t\u00e9 par des aiguilles douphine tr\u00e8s aff\u00fbt\u00e9es et une surface \u00e0 double pente. Le bo\u00eetier en or rose massif 18 carats \u00e0 cornes \"capot\" est un chef-d'\u0153uvre du ma\u00eetre genevois Antoine Gerlach, actif des ann\u00e9es 1930 aux ann\u00e9es 1970 (poin\u00e7on cl\u00e9 : \"4\"). C'est cet artiste qui, \u00e0 partir de 1932, a cr\u00e9\u00e9 certains des bo\u00eetiers les plus beaux et les plus embl\u00e9matiques de Patek Philippe. Il a r\u00e9alis\u00e9 le bo\u00eetier en or embl\u00e9matique de la Calatrava 96R (1941) et celui du quanti\u00e8me perp\u00e9tuel \"Disco Volante\" 3448 (d\u00e9but des ann\u00e9es 1970). Gerlach a \u00e9galement beaucoup collabor\u00e9 avec Omega. Il a con\u00e7u et produit les bo\u00eetiers des Constellation avec des cadrans pie-pan \"immatures\" (ou \"pseudo-pie-pan\") entre les ann\u00e9es 1950 et 1960. En bref, un grand ma\u00eetre-\u00e9tuyer qui a cr\u00e9\u00e9 certaines des montres les plus embl\u00e9matiques de tous les temps \u00e0 Gen\u00e8ve. Ce splendide bo\u00eetier est associ\u00e9 \u00e0 un tout aussi splendide bracelet construit avec des intervalles de quatre et trois tr\u00e8s petits maillons souples. Il se termine par un fermoir r\u00e9glable qui assure confort et s\u00e9curit\u00e9 au poignet. Sous le pr\u00e9cieux fond de bo\u00eete de cette montre se trouve le calibre automatique Omega 342. Il est entr\u00e9 en production en 1949 et a redessin\u00e9 le calibre 340 datant de quelques mois afin d'am\u00e9liorer sa fonction de remontage. L'Omega 342 mesure 28,5 mm de large et 4,8 mm d'\u00e9paisseur ; il poss\u00e8de 17 rubis, une r\u00e9serve de marche de 42 heures et une fr\u00e9quence de 19 800 tours par minute.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/09\/OMEGA-AUTOMATIC-_GERLACH_-18KT-ROSE-GOLD_1_1.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/09\/OMEGA-AUTOMATIC-_GERLACH_-18KT-ROSE-GOLD_1_1.jpg","width":2013,"height":2013},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/omega-automatic-gerlach-18kt-rose-gold-case-in-house-self-winding-movement-342-from-the-1950s\/#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 Automatic “Gerlach” 18KT Rose Gold Case In-House Self-Winding Movement 342 From the 1950s"}]},{"@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":"instock","product_availability":"instock","product_retailer_item_id":"835","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/62482","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=62482"}],"version-history":[{"count":1,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/62482\/revisions"}],"predecessor-version":[{"id":63240,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/62482\/revisions\/63240"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media\/63239"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media?parent=62482"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_brand?post=62482"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_cat?post=62482"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_tag?post=62482"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
