Professionals such as Architects and Engineers could perform calculations and measurements by means of a bezel with a logarithmic slide rule that moved bi-directionally. In fact, before the advent of the electronic calculator, the slide rule was one of the most valuable and useful accessories that could be owned: by means of the operation of the slide rule it was possible to calculate complicated equations applied to engineering and trigonometry. The Arithmo glass is very unique, which collectors call &quot;doughnut&quot; but which is more technically defined as &quot;Refrascope&quot;: the main dial is covered by a separate piece of the crystal system from the slide rule bezels. The look is truly unlike any other and allows for a clear view of the slide rule, while still being able to rotate. When the wearer rotates the bezel, the outer plexiglass part rotates with it while the inner part, above the central dial, remains fixed. In 1945, Juvenia launched the first variations of this patent on wristwatches that are now highly sought after by collectors around the world. This is a very rare example and in an incredible state of preservation. The dial is glossy black with gilt graphics made with a galvanic technique. The Arabic numerals are interspersed with rectangular indexes and on the outer edge runs a sequence of circular indications delimited by a thin golden ring. At the center of the dial at 12 o&#039;clock is the Juvenia Arithmo signature placed in gold glitter. The bezel is bi-partite: internally it is still black with gilt numbering and notches for measurement; the outermost section is in steel and the numbering is engraved and painted in black. The original &quot;Refrascope&quot; crystal is ultra-curved and creates surprising plays of light distortion on the dial. The gold hands have a beautiful sword shape with handle; the central seconds hand has a more classic shape: it is threadlike with a seed-shaped counterweight. The case is a spectacular oversize in the shape of a flattened disk. On it stands the rotating bezel and above it still the crystal. The original crown is recessed into the case so as not to break the sinuous bulging profile. The large &quot;drop&quot; lugs are wonderful: they start from above the case to literally fall downwards and fold back on themselves. It is a succession of lines with a circular development. A great visual effect. Inside we find the tried and tested AS 1180 movement with manual winding of 8 3\/4 lines with direct central seconds.

This is an extremely rare and unrepeatable watch.","og_url":"https:\/\/thevintageur.com\/de\/shop\/juvenia-arithmo-jumbo-schwarzes-zifferblatt-handaufzugswerk-aus-den-50ern\/","og_site_name":"The Vintageur","article_modified_time":"2025-07-15T18:28:27+00:00","og_image":[{"width":2560,"height":2560,"url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF1148.jpg","type":"image\/jpeg"}],"twitter_card":"summary_large_image","twitter_misc":{"Preis":"","Verf\u00fcgbarkeit":"ausverkauft"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/","url":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/","name":"JUVENIA ARITHMO JUMBO BLACK DIAL MANUAL WINDING MOVEMENT FROM 50S - The Vintageur","isPartOf":{"@id":"https:\/\/thevintageur.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/#primaryimage"},"image":{"@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/#primaryimage"},"thumbnailUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF1148.jpg","datePublished":"2025-05-02T07:38:25+00:00","dateModified":"2025-07-15T18:28:27+00:00","description":"SPEZIFIKATIONEN 42-mm-Verbundgeh\u00e4use Original-Krone Original-\"Refrascope\"-Glas AS 1180-Handaufzugswerk ANALYSE Die Juvenia Arithmo entstand aus einem Patent aus dem Jahr 1944 f\u00fcr eine Tischuhr, die komplexe arithmetische Berechnungen durchf\u00fchren konnte. Fachleute wie Architekten und Ingenieure konnten Berechnungen und Messungen mit Hilfe einer L\u00fcnette mit einem logarithmischen Rechenschieber durchf\u00fchren, der sich in beide Richtungen bewegte. Tats\u00e4chlich war der Rechenschieber vor dem Aufkommen des elektronischen Taschenrechners eines der wertvollsten und n\u00fctzlichsten Zubeh\u00f6rteile, die man besitzen konnte: Mit Hilfe des Rechenschiebers war es m\u00f6glich, komplizierte Gleichungen in der Technik und Trigonometrie zu berechnen. Das Arithmo-Glas ist einzigartig und wird von Sammlern als \"Doughnut\" bezeichnet, technisch gesehen jedoch als \"Refrascope\": Das Hauptzifferblatt wird von einem separaten Teil des Kristallsystems der Rechenschiebereinfassung bedeckt. Dieses einzigartige Design erm\u00f6glicht einen klaren Blick auf den Rechenschieber, w\u00e4hrend sich die Uhr gleichzeitig drehen l\u00e4sst. Wenn der Tr\u00e4ger die L\u00fcnette dreht, dreht sich der \u00e4u\u00dfere Teil aus Plexiglas mit, w\u00e4hrend der innere Teil \u00fcber dem zentralen Zifferblatt fixiert bleibt. 1945 brachte Juvenia die ersten Varianten dieses Patents f\u00fcr Armbanduhren auf den Markt, die heute bei Sammlern in aller Welt sehr begehrt sind. Dies ist ein sehr seltenes Exemplar und in einem unglaublichen Erhaltungszustand. Das Zifferblatt ist gl\u00e4nzend schwarz mit vergoldeten Grafiken, die mit einer galvanischen Technik hergestellt wurden. Die arabischen Ziffern sind mit rechteckigen Indexen durchsetzt, und am \u00e4u\u00dferen Rand verl\u00e4uft eine Reihe kreisf\u00f6rmiger Anzeigen, die von einem d\u00fcnnen goldenen Ring begrenzt werden. In der Mitte des Zifferblatts bei 12 Uhr befindet sich der Schriftzug Juvenia Arithmo in Goldglitter. Die L\u00fcnette ist zweiteilig: innen noch schwarz mit vergoldeter Nummerierung und Messkerben; der \u00e4u\u00dfere Teil ist aus Stahl und die Nummerierung ist eingraviert und schwarz lackiert. Das originale \"Refrascope\"-Glas ist extrem gew\u00f6lbt und erzeugt auf dem Zifferblatt \u00fcberraschende Lichtspiele. Die goldenen Zeiger haben eine sch\u00f6ne Schwertform mit Griff; der zentrale Sekundenzeiger hat eine klassischere Form: Er ist fadenf\u00f6rmig mit einem samenf\u00f6rmigen Gegengewicht. Das Geh\u00e4use ist ein spektakul\u00e4res Oversize-Geh\u00e4use in Form einer abgeflachten Scheibe. Auf ihm steht die drehbare L\u00fcnette und dar\u00fcber noch das Glas. Die originale Krone ist in das Geh\u00e4use eingelassen, um das gewundene, gew\u00f6lbte Profil nicht zu unterbrechen. Wundersch\u00f6n sind die gro\u00dfen \"Drop\"-Stollen: Sie beginnen oberhalb des Geh\u00e4uses, fallen buchst\u00e4blich nach unten und falten sich auf sich selbst zur\u00fcck. Es ist eine Abfolge von Linien mit einer kreisf\u00f6rmigen Entwicklung. Ein gro\u00dfartiger optischer Effekt. Im Inneren finden wir das bew\u00e4hrte Werk AS 1180 mit Handaufzug mit 8 3\/4 Linien und direkter Zentralsekunde. Dies ist eine \u00e4u\u00dferst seltene und unwiederholbare Uhr.","breadcrumb":{"@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/#breadcrumb"},"inLanguage":"de","potentialAction":[{"@type":"ReadAction","target":["https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/"]}]},{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/#primaryimage","url":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF1148.jpg","contentUrl":"https:\/\/thevintageur.com\/wp-content\/uploads\/2025\/04\/DSCF1148.jpg","width":2560,"height":2560},{"@type":"BreadcrumbList","@id":"https:\/\/thevintageur.com\/shop\/juvenia-arithmo-jumbo-black-dial-manual-winding-movement-from-50s\/#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 ARITHMO JUMBO BLACK DIAL MANUAL WINDING MOVEMENT FROM 50S"}]},{"@type":"WebSite","@id":"https:\/\/thevintageur.com\/#website","url":"https:\/\/thevintageur.com\/","name":"Der Winzer","description":"Ihre ma\u00dfgefertigte Uhrenkollektion","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":"de"},{"@type":"Organization","@id":"https:\/\/thevintageur.com\/#organization","name":"Der Winzer","url":"https:\/\/thevintageur.com\/","logo":{"@type":"ImageObject","inLanguage":"de","@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":"341","product_condition":"new"},"_links":{"self":[{"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product\/54833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/comments?post=54833"}],"version-history":[{"count":0,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product\/54833\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/media\/54836"}],"wp:attachment":[{"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/media?parent=54833"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product_brand?post=54833"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product_cat?post=54833"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/thevintageur.com\/de\/wp-json\/wp\/v2\/product_tag?post=54833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
