Citizen's answer was the Crystron Diver: a JDM-only professional quartz dive watch of almost identical intent, produced from approximately 1978 to 1981, that has since become one of the rarest and most sought-after items in vintage Japanese watch collecting precisely because so few were produced and even fewer have survived in good condition.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe \"Crystron\" designation identifies this as part of Citizen's higher-end electronic\/quartz line of the late 1970s — watches that sat above the standard Citizen production in specification, price, and ambition. The CQ (Crystron Quartz) designation on the dial confirms the hierarchy. At 41-42mm the case is large for its era, with a stainless steel monocoque construction, screw-in caseback, unidirectional rotating bezel with its distinctive knurled pattern of 60 clicks, and a dial layout that is immediately legible at any depth or angle.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan\u003eWHATS INSIDE:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eThe Crystron Diver is powered by a Citizen quartz movement, providing low-maintenance timekeeping.\u003c\/span\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":"Citizen","offers":[{"title":"Default Title","offer_id":54092320145681,"sku":"24746","price":475.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0072\/5332\/7960\/files\/Citizen-1980s-Crystron-Diver-150247461-7.jpg?v=1788575444","url":"https:\/\/fivefortyfive.nz\/products\/citizen-1980s-crystron-diver-150","provider":"FiveFortyFive","version":"1.0","type":"link"}
