Introduced in 1967, the name belonged to the brand’s push into high-frequency mechanical timekeeping, but this example also catches the design change happening around it: the conventional round dress watch giving way to a broader cushion case, a metallic dial and a woven bracelet that feels unmistakably of its period.\u003c\/p\u003e\n\u003cp\u003eThat combination is what gives this one its presence. The silver dial is restrained until the light catches its fine radial finish, while the small Ultra-Chron emblem supplies the clue that something more interesting was happening beneath the surface. Add the signed mesh bracelet and it becomes a lovely expression of Longines at the turn of the 1970s, precision engineering dressed for a new decade.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eA BIT OF TRIVIA\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eLongines’ interest in high frequency did not begin with the Ultra-Chron. The company traces its work in high-frequency timing back to 1910, and in 1959 developed the 5 Hz Calibre 360 observatory chronometer. The Ultra-Chron brought that thinking into a production wristwatch in 1967. Its first-generation Calibre 431 ran at 5 Hz, with the balance making ten beats every second, serious mechanical ambition at a time when most wristwatches were beating considerably more slowly.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eOUR THOUGHTS\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eWe like Ultra-Chrons because the clever bit is not hidden behind a loud watch. This one has the technical story, but what caught us first was the combination of that silver dial, broad cushion case and signed Longines mesh bracelet. It looks like the moment the 1960s handed the drawing board to the 1970s, and the Ultra-Chron emblem quietly tells you why the watch mattered.\u003c\/p\u003e","brand":"Past2PresentWatches","offers":[{"title":"Default Title","offer_id":62667595776387,"sku":"LUC5106WO","price":825.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/2397\/4423\/files\/longines-ultrachron-8317-front-_8.jpg?v=1790949749","url":"https:\/\/past2presentwatches.com\/products\/vintage-longines-ultra-chron-8317-watch-1971-serviced-uk-warranty","provider":"Past2PresentWatches","version":"1.0","type":"link"}
