At the time, Longines had already established itself as a pioneer in high-frequency technology. As early as 1910, the winged hourglass brand created the first high-frequency timekeeping device capable of measuring 1\/10th of a second. In 1959, Longines developed the first high-beat movement for a wristwatch, an observatory chronometer that set new records in terms of accuracy. The new Ultra-Chron is inspired by the aesthetic codes and professional diving features of the 1968 model. These chronometer-certified watches are powered by an exclusive Longines calibre equipped with a silicon balance-spring and resistant to magnetic fields.<\/p>\n","protected":false},"featured_media":135655,"template":"","meta":{"_acf_changed":false},"product_brand":[390],"product_cat":[491,493],"product_tag":[],"product_collection":[1319],"class_list":["post-221275","product","type-product","status-publish","has-post-thumbnail","product_brand-longines-en","product_cat-new","product_cat-watches","product_collection-ultra-chron","first","outofstock","shipping-taxable","purchasable","product-type-simple"],"acf":{"product_is_new":false,"product_not_available":false,"product_related_stores":null,"product_infos":"","product_features":[{"title":"Case","description":"<b>Shape<\/b> : Round<br><b>Material<\/b> : Stainless steel<br><b>Glass<\/b> : Scratch-resistant sapphire crystal, with several layers of anti-reflective coating on both sides<br><b>Dimension<\/b> : \u00d8\u00a037.00\u00a0mm<br><b>Lug distance<\/b> : 19 mm<br><b>Lug-to-lug<\/b> : 44.60 mm<br><b>Thickness<\/b> : 10.95 mm<br><b>Water Resistance<\/b> : Water-resistant to 5 bar<br><b>Weight<\/b> : 59.0 g<br>"},{"title":"Dial & Hands","description":"<b>Dial color<\/b> : Sunray silver<br><b>Hour markers<\/b> : Applied indexes<br><b>Hands<\/b> : Silvered polished hands<br>"},{"title":"Movement & Functions","description":"<b>Movement Type<\/b> : Automatic<br><b>Functions<\/b> : Hours, minutes, seconds and date<br><b>Caliber<\/b> : L836.6<br><b>Movement Description<\/b> : Self winding mechanical movement beating at 36'000 vibrations per hour, with a monocrystalline silicon balance-spring power reserve up to 52 hours<br>"},{"title":"Strap","description":"<b>Upper<\/b> : Alligator leather<br><b>Back side<\/b> : Calf leather<br><b>Color<\/b> : Black<br><b>Buckle<\/b> : With buckle<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"},{"title":"General","description":"<b>Magnetic resistant<\/b> : Yes<br><b>Chronometer Officially Certified<\/b> : Yes<br>"}],"product_cta_title":"","product_cta_descr":"","product_cta_btn":null,"product_cta_img":null},"_links":{"self":[{"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product\/221275","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/media\/135655"}],"wp:attachment":[{"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/media?parent=221275"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product_brand?post=221275"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product_cat?post=221275"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product_tag?post=221275"},{"taxonomy":"product_collection","embeddable":true,"href":"https:\/\/lionel-meylan.ch\/en\/wp-json\/wp\/v2\/product_collection?post=221275"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
