The 36 mm stainless steel case and 41 mm lug-to-lug measurement keep the watch compact and balanced, while the original metal bracelet gives it a more substantial factory appearance on the wrist. The silver dial is deliberately uncluttered, relying on applied baton markers, a framed date aperture and fine linear detailing rather than decorative excess. Its polished bezel and angular case shoulders create a clear transition between the round dial and the integrated-looking bracelet. The overall result is practical, refined and unmistakably rooted in Seiko’s quartz-era design language.\u003c\/p\u003e\u003ch3\u003eSeiko SQ - Silver Sunburst Dial\u003c\/h3\u003e\u003cp\u003eThe dial has a pale silver sunburst finish with fine radial brushing that changes subtly with the direction of light. Applied silver-tone baton hour markers are arranged around the perimeter, including a doubled marker at 12 o’clock for immediate orientation. A fine printed minute track sits close to the outer edge and keeps the display precise without making it visually busy. The SEIKO signature appears beneath 12 with QUARTZ directly below it, while the SQ emblem is positioned above 6 o’clock. A framed date window at 3 o’clock uses a dark numeral against a light background for clear contrast. At the lower edge, the JAPAN movement and dial-code marking remains visible and reinforces the watch’s original Japanese production identity.\u003c\/p\u003e\u003ch3\u003eSQ 7545-7030 - Hands\u003c\/h3\u003e\u003cp\u003eThe hour and minute hands use slim silver-tone baton forms with pale luminous-style inserts that coordinate with the applied markers. Their proportions are well matched to the dial, with the minute hand reaching toward the outer scale while the shorter hour hand remains clearly distinguishable. A slender central seconds hand completes the three-hand display and preserves the clean symmetry of the dial. The handset shows only light age-related character and remains easy to read against the bright silver background. No additional complication is placed on the dial beyond the date, allowing the simple geometry of the markers and hands to remain the principal visual theme.\u003c\/p\u003e\u003ch2\u003eSeiko SQ 7545-7030 - Stainless Steel Case\u003c\/h2\u003e\u003cp\u003eThe case is confirmed as stainless steel and uses a softly angular late-1970s profile with broad shoulders and a polished circular bezel. At 36 mm across, it remains classically proportioned, but the case shape and bracelet integration give it more presence than the diameter alone suggests. Polished surfaces around the bezel contrast with the flatter upper case planes, emphasizing the transition from the round dial opening into the wider body. Light scratches and age-related marks are visible on the steel under close inspection, consistent with regular use over several decades. The original geometry remains clear, and the case has not been described as freshly refinished or cosmetically perfect.\u003c\/p\u003e\u003ch3\u003eSQ 7545-7030 - Crown\u003c\/h3\u003e\u003cp\u003eA compact ridged crown sits at 3 o’clock and is tucked close to the case flank, helping preserve the watch’s streamlined profile. Its size is appropriate for a quartz watch, where regular winding is unnecessary, while still providing sufficient grip for time and date adjustment. No crown signature is clearly visible in the supplied photograph, so no signed-crown claim is made. The crown’s restrained scale and simple shape suit the practical, low-profile character of the SQ design.\u003c\/p\u003e\u003ch3\u003eSeiko SQ Original Stainless Steel Bracelet\u003c\/h3\u003e\u003cp\u003eThe watch is fitted with an original signed Seiko SQ stainless steel bracelet, as specifically stated in the supplied record. The bracelet uses broad outer sections with narrower articulated center links, producing a flexible multi-link construction that visually continues the steel case. Its period-correct design is important to the overall appearance because the watch and bracelet read as a complete late-1970s factory ensemble rather than as a watch head fitted to a modern replacement strap. Light scratches and surface wear are visible across the links, consistent with vintage use. An exact fitted wrist circumference is not supplied, so the bracelet is described as adjustable rather than assigned to a specific wrist size.\u003c\/p\u003e\u003ch2\u003eSeiko SQ 1979 - Japanese Quartz Analog 7545 with Date\u003c\/h2\u003e\u003cp\u003eThe movement is identified in the supplied product data as Seiko Caliber 7545, a Japanese quartz analog movement powering the central hour, minute and seconds display together with the date complication. No unsupported jewel count, frequency or battery-life figure is added. Quartz operation provides straightforward ownership and stable everyday timekeeping without the regular winding routine required by a mechanical watch. This example is recorded as serviced.

This 1979 example reflects that transition through a restrained silver dial, compact stainless steel proportions, a simple date display and an original bracelet designed as part of the complete watch. The visual language remains conservative enough for dress use, yet the angular case and bracelet structure give it a more contemporary character than many traditional mechanical watches of the same decade. Its appeal lies in this balance of functionality and period design.

The supplied record does not explicitly state a complete all-original status for every watch component, so no broader originality claim is added beyond what is documented. The silver sunburst dial presents cleanly, while the stainless steel case and bracelet show light scratches and normal age-related surface wear visible in the supplied photograph. No box or papers are included. The watch is supplied with a 12-month warranty and is available for worldwide shipping from Vintage Watch Studio. Water resistance should not be assumed unless separately tested and documented. The combination of a clean silver dial, compact steel case, original bracelet and Seiko 7545 quartz movement gives this 1979 SQ a particularly coherent late-1970s presentation.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSeiko\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSQ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference\u003c\/td\u003e\n\u003ctd\u003e7545-7030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eVery Good Vintage Condition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGender\u003c\/td\u003e\n\u003ctd\u003eMen’s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCaliber\u003c\/td\u003e\n\u003ctd\u003e7545\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCategory\u003c\/td\u003e\n\u003ctd\u003eDress Vintage Watch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduction Year\u003c\/td\u003e\n\u003ctd\u003e1979 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Color\u003c\/td\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Diameter\u003c\/td\u003e\n\u003ctd\u003e36 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug to Lug\u003c\/td\u003e\n\u003ctd\u003e41 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug Width\u003c\/td\u003e\n\u003ctd\u003e18 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWrist Size\u003c\/td\u003e\n\u003ctd\u003eAdjustable bracelet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMovement Type\u003c\/td\u003e\n\u003ctd\u003eQuartz Analog\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBox\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePapers\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFully Serviced\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e12 Months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":44494214103105,"sku":null,"price":280.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/2768\/1857\/files\/seiko-sq-ref-7545-7030-cal-7545-mens-quartz-analog.webp?v=1788077263","url":"https:\/\/www.vintagewatchstudio.com\/products\/seiko-sq-ref-7545-7030-cal-7545-mens-quartz-analog","provider":"Vintage Watch Studio","version":"1.0","type":"link"}
