The tuning fork technology was licensed from Bulova's Accutron patents via the ETA\/ESA manufacturing organisation, and it gave the Ultronic a seconds hand that glides continuously rather than stepping — the defining observable characteristic that separated tuning fork watches from both their mechanical predecessors and their quartz successors.\u003c\/p\u003e\n\u003cp\u003eThe Flagship Ultronic in this blue dial configuration is a lovely piece. The deep blue with its applied silver-tone baton markers and \"\u003cem\u003eFLAGSHIP ULTRONIC\u003c\/em\u003e\" text at lower centre is period-correct and in the richest of the colour options the Flagship Ultronic was produced in. The date at 3 o'clock is framed within a white date disc.\u003c\/p\u003e\n\u003cp\u003eWHAT'S INSIDE:\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe Longines Flagship Ultronic is powered by the Calibre 6312 — Longines' designation for the ESA 9162 tuning fork movement, a 12-jewel electronic movement operating at 300Hz with an electrical hack feature. The tuning fork vibrates at 300 times per second, driven by a battery and transistor circuit, and controls the gear train through a tiny pawl that advances with each vibration.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eFIVEFORTYFIVE SIX MONTHS \u003cspan style=\"color: #ff2a00;\"\u003eWARRANTY\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":54372694065425,"sku":"24820","price":2250.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0072\/5332\/7960\/files\/Longines-1970s-Flagship-Ultronic-Tuning-Fork248201-7.jpg?v=1787621551","url":"https:\/\/fivefortyfive.nz\/products\/longines-1970s-flagship-ultronic-tuning-fork","provider":"FiveFortyFive","version":"1.0","type":"link"}
