Montre de poche Juvenia Mathematic Arithmo extr\u00eamement rare des ann\u00e9es 1950, nouveau stock ancien.<\/p>\n

Bo\u00eetier en acier inoxydable de 57 mm, fermeture \u00e0 glissi\u00e8re.<\/p>\n

Superbe cadran argent\u00e9 avec aiguilles en or.<\/p>\n

Mouvement \u00e0 remontage manuel sign\u00e9 Juvenia.<\/p>\n

Cristal en plastique d'origine, en parfait \u00e9tat.<\/p>\n

Cette \u00e9tonnante montre, originale dans toutes ses parties, est pr\u00e9sent\u00e9e avec une merveilleuse patine du temps qui la rend certainement impressionnante et \u00e9l\u00e9gante.<\/p>\n

La Juvenia Arithmo, pr\u00e9sent\u00e9e en 1945, est un garde-temps pratique qui permet au porteur d'effectuer de nombreux calculs gr\u00e2ce \u00e0 une r\u00e8gle \u00e0 calcul munie d'une lunette tournante. Les mod\u00e8les Mimo Loga et Breitling Chronomat pr\u00e9sentent un concept similaire. Avant l'apparition des calculatrices \u00e9lectroniques, la r\u00e8gle \u00e0 calcul \u00e9tait l'un des accessoires les plus pr\u00e9cieux et les plus utiles que l'on puisse poss\u00e9der. Une fois que l'on a compris le fonctionnement de la r\u00e8gle \u00e0 calcul, on peut calculer des \u00e9quations compliqu\u00e9es, appliqu\u00e9es \u00e0 tous les besoins, de l'ing\u00e9nierie \u00e0 la trigonom\u00e9trie. L'Arithmo permet \u00e0 son porteur de ne jamais oublier sa r\u00e8gle \u00e0 calcul \u00e0 la maison, puisqu'elle est toujours \u00e0 port\u00e9e de main.<\/p>\n

Juvenia a commercialis\u00e9 l'Arithmo \u00e0 l'\u00e9poque comme \"la premi\u00e8re montre calculatrice pratique\". Alors qu'il en existait d'autres sur le march\u00e9, la marque estimait qu'elle \u00e9tait, en fait, la seule option pratique. Cela peut \u00eatre discut\u00e9, et nous sommes s\u00fbrs que Breitling avait quelque chose \u00e0 dire \u00e0 ce sujet dans les ann\u00e9es 1940. Peut-\u00eatre cette opinion de praticit\u00e9 trouve-t-elle son origine dans la construction du cristal de l'Arithmo, qui \u00e9tait certainement unique \u00e0 cette montre. Les collectionneurs qualifient la glace de l'Arithmo de \"donut-shaped\" (en forme de beignet), car le cadran principal est recouvert d'une pi\u00e8ce distincte du syst\u00e8me cristallin par rapport aux lunettes de la r\u00e8gle \u00e0 calcul. Cette forme ne ressemble \u00e0 rien d'autre et permet de voir clairement la r\u00e8gle \u00e0 calcul tout en conservant la possibilit\u00e9 de tourner. Lorsque le porteur fait tourner la lunette, la partie ext\u00e9rieure en plexiglas tourne avec elle, tandis que la partie int\u00e9rieure, qui recouvre le cadran central, reste fixe.<\/p>","protected":false},"excerpt":{"rendered":"

The Juvenia Arithmo, introduced in 1945, is a practical timepiece allowing the wearer to perform many calculations with the installment of a slide rule scale with a rotating bezel.

Les collectionneurs qualifient la glace de l'Arithmo de \"donut-shaped\" (en forme de beignet), car le cadran principal est recouvert d'une pi\u00e8ce distincte du syst\u00e8me cristallin par rapport aux lunettes de la r\u00e8gle \u00e0 calcul. Cette forme ne ressemble \u00e0 rien d'autre et permet de voir clairement la r\u00e8gle \u00e0 calcul tout en conservant la possibilit\u00e9 de tourner. Lorsque le porteur fait tourner la lunette, la partie ext\u00e9rieure en plexiglas tourne avec elle, tandis que la partie int\u00e9rieure, qui recouvre le cadran central, reste fixe.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/juvenia-mathematic-arithmo-pocket-watch-new-old-stock\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/juvenia-mathematic-arithmo-pocket-watch-new-old-stock\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/thevintageur.com\/shop\/juvenia-mathematic-arithmo-pocket-watch-new-old-stock\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2024\/04\/PB180264.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2024\/04\/PB180264.jpg","width":3216,"height":3216,"caption":"OLYMPUS DIGITAL CAMERA"},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/juvenia-mathematic-arithmo-pocket-watch-new-old-stock\/#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":"Juvenia\u00a0Mathematic Arithmo pocket watch new old stock"}]},{"@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":"9500.00","product_price_currency":"EUR","og_availability":"instock","product_availability":"instock","product_retailer_item_id":"293","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/6961","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=6961"}],"version-history":[{"count":0,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product\/6961\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media\/14340"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/media?parent=6961"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_brand?post=6961"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_cat?post=6961"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/fr\/wp-json\/wp\/v2\/product_tag?post=6961"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
