Longines Ultra-Chron Ref. 8348, crafted in solid 18 kt yellow gold and preserved in mint condition. Dating from the early 1970s, this unusual model features the distinctive Ultra-Chron case design with its characteristic faceted architecture and twelve-sided caseback. The refined dial is complemented by applied baton hour markers, elegant hands, central seconds and a date aperture, creating a sophisticated yet highly functional vintage aesthetic.\nAt its heart is the legendary Longines Calibre 431, an automatic high-frequency movement beating at 36,000 vibrations per hour (5 Hz), developed for the Ultra-Chron collection and renowned for its exceptional precision and remarkably smooth seconds-hand motion. A particularly desirable and uncommon solid-gold reference, the 8348 represents one of the most refined expressions of Longines\u2019 high-frequency watchmaking of the period.\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-61f9ef0 elementor-widget elementor-widget-text-editor\" data-id=\"61f9ef0\"

rare and exceptionally elegant Longines Ultra-Chron Ref. 8348, crafted in solid 18 kt yellow gold and preserved in mint condition. Dating from the early 1970s, this unusual model features the distinctive Ultra-Chron case design with its characteristic faceted architecture and twelve-sided caseback. The refined dial is complemented by applied baton hour markers, elegant hands, central seconds and a date aperture, creating a sophisticated yet highly functional vintage aesthetic.<br \/>\nAt its heart is the legendary Longines Calibre 431, an automatic high-frequency movement beating at 36,000 vibrations per hour (5 Hz), developed for the Ultra-Chron collection and renowned for its exceptional precision and remarkably smooth seconds-hand motion. A particularly desirable and uncommon solid-gold reference, the 8348 represents one of the most refined expressions of Longines\u2019 high-frequency watchmaking of the period.<\/p>\n","protected":false},"author":7,"featured_media":15866,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[19,7,43,64,74],"tags":[47,57],"class_list":["post-15863","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-classic","category-longines","category-new-arrivals","category-time-only","category-vintage","tag-in-stock","tag-new-arrivals"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/posts\/15863","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=15863"}],"version-history":[{"count":9,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/posts\/15863\/revisions"}],"predecessor-version":[{"id":15883,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/posts\/15863\/revisions\/15883"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=\/wp\/v2\/media\/15866"}],"wp:attachment":[{"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=15863"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=15863"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vintagewatchesmilano.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=15863"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
