Where Swiss manufacturers were producing quartz chronographs with 1\/5th or 1\/10th second resolution, Seiko's 7T52 doubled the precision of the best available quartz chronograph resolution at the time, displaying it across three analogue sub-registers with red accent hands. In the JDM market this reference was marketed under the \"Speedmaster\" name — the same designation Seiko had used for their motorsport chronograph line since the 1960s — reflecting the tachymeter-equipped, high-precision timing brief the watch was designed to fulfil.\u003c\/p\u003e\n\u003cp\u003eThe case architecture is the other immediately distinctive detail. The angular, cushion-influenced silhouette with its four cylindrical pushers positioned at the 2, 8, and 10 o'clock positions gives the 7T52-6A30 a purposeful, sport-instrument appearance that separates it visually from the conventional two-pusher chronographs of its era.\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 7T52-6A30 is powered by Seiko Calibre 7T52 — Seiko's first quartz chronograph movement with 1\/100th second analogue display capability, a battery-powered Japanese quartz movement with three analogue sub-registers.\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":"Seiko","offers":[{"title":"Default Title","offer_id":54092884705553,"sku":"24752","price":450.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0072\/5332\/7960\/files\/Seiko-1993-Chronograph247521-7.jpg?v=1787620814","url":"https:\/\/fivefortyfive.nz\/products\/seiko-1993-speedmaster-chronograph-1-100-jdm","provider":"FiveFortyFive","version":"1.0","type":"link"}
