The &#8220;Business-A&#8221; name dropped the &#8220;matic&#8221; branding and spoke directly to its target market: the Japanese salaryman who needed a slim, dependable automatic that would perform every day under a suit jacket sleeve.<\/p>\n<p>The <strong>&#8220;A&#8221; stands for Automatic<\/strong> \u2014 a confident, understated statement. Where earlier Seiko branding had marketed the technology itself, the Business-A assumed automatic winding was simply expected. This was a watch for people who already knew what they wanted.<\/p>\n<p>The caliber beneath changed too. The Business-A moved to Seiko&#8217;s <strong>83-series movements<\/strong>, purpose-built by the Suwa factory to be thin without sacrificing capability. The <strong>caliber 8346A<\/strong> \u2014 the movement in this watch \u2014 is a day-date automatic running at <strong>18,000 vph<\/strong> with <strong>Diashock<\/strong> shock protection and <strong>27 jewels<\/strong>. It offers manual-winding backup, quick-set date function, and the full day-of-week display: weekdays rendered in blue, Sunday and weekend days in red. In 1967, a full day-date display at this price point was a genuine luxury feature that most competitors didn&#8217;t offer.<\/p>\n<p>The dial design is characteristic Business-A restraint: a <strong>silver sunburst surface<\/strong>, applied cross-shaped indices at all twelve positions, no chapter ring, no bezel markings. Just the dial, the hands, and the indices. The crown sits at the standard 3 o&#8217;clock position \u2014 unlike the Seikomatic-R&#8217;s hidden 4 o&#8217;clock crown \u2014 signaling that this is a watch you&#8217;re meant to use, not just admire.<\/p>\n<p>The Business-A line was produced from approximately 1967 to 1972, when Seiko gradually consolidated its lineup under new naming conventions. It represents a narrow window of production at peak mid-range Suwa quality, and is only now beginning to attract the collector attention it deserves.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>Technical Specifications<\/strong><\/h3>\n<table>\n<tbody>\n<tr>\n<td><strong>Brand<\/strong><\/td>\n<td>Seiko<\/td>\n<\/tr>\n<tr>\n<td><strong>Line<\/strong><\/td>\n<td>Business-A<\/td>\n<\/tr>\n<tr>\n<td><strong>Reference Number<\/strong><\/td>\n<td>8346-9020<\/td>\n<\/tr>\n<tr>\n<td><strong>Movement<\/strong><\/td>\n<td>Caliber 8346A, automatic (self-winding + manual wind), 27 jewels, Diashock, 18,000 vph<\/td>\n<\/tr>\n<tr>\n<td><strong>Serial Number<\/strong><\/td>\n<td>7609486<\/td>\n<\/tr>\n<tr>\n<td><strong>Production Date<\/strong><\/td>\n<td>June 1967<\/td>\n<\/tr>\n<tr>\n<td><strong>Case Material<\/strong><\/td>\n<td>Stainless steel, water resistant(vintage)<\/td>\n<\/tr>\n<tr>\n<td><strong>Dial<\/strong><\/td>\n<td>Silver sunburst, applied cross indices, day-date display (weekdays in blue, Sunday in red)<\/td>\n<\/tr>\n<tr>\n<td><strong>Caseback Features<\/strong><\/td>\n<td>Screw-back stainless steel; engraved ref. 8346-9020, serial 7609486; WATER PROOF<\/td>\n<\/tr>\n<tr>\n<td><strong>Country of Manufacture<\/strong><\/td>\n<td>Japan<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h3><strong>Condition Report<\/strong><\/h3>\n<p>This Business-A presents well for its age. The dial is clean with no significant spotting, fading, or damage \u2014 the silver sunburst surface retains good depth. The applied cross indices are all intact and properly seated. The case shows light surface wear consistent with nearly six decades of use \u2014 no major dings or deep scratches. The screw-back case back shows normal scuff marks but is fully intact. The original stainless steel bracelet is present and functional, with the signed Seiko clasp.<\/p>\n<p>Watch been through a recent service by a professional watch tech and keeps good time.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>Why Collectors and Enthusiasts Want This Watch Today<\/strong><\/h3>\n<p>The Business-A occupies a sweet spot that few vintage Seikos hit: genuine 1960s pedigree, a 27-jewel movement with Diashock, a full day-date complication, and the kind of clean, restrained dial design that works equally well with a formal shirt or a weekend outfit. It&#8217;s more interesting than a standard Seiko 5 and significantly more accessible than a King Seiko or early Grand Seiko.<\/p>\n<p>The <strong>8346 caliber<\/strong> is under-appreciated. It&#8217;s a slim, high-jewel movement with ruby bearings, properly finished for its tier, and capable of excellent timekeeping when regulated. The dual color day display \u2014 blue for weekdays, red for Sunday \u2014 is a small but genuine luxury touch that most competitors didn&#8217;t offer at this price point in 1967.<\/p>\n<p>This specific reference (-9020) came with the original steel bracelet, which many examples have long since lost. Intact original bracelets add meaningfully to period-correct presentation and are increasingly difficult to find in good condition.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Comes complete with original stainless steel bracelet*.<\/strong><\/p>\n<p>(*) Note: Stock bracelets are often shortened by previous owners and may not fit every wrist (see bracelet sizing in the product images).

Founded in 1881 by <a title=\"Kintar\u014d Hattori\" href=\"https:\/\/en.wikipedia.org\/wiki\/Kintar%C5%8D_Hattori\">Kintar\u014d Hattori<\/a> in Tokyo, Seiko introduced the world&#8217;s first commercial <a title=\"Quartz clock\" href=\"https:\/\/sovietwatchstore.com\/index.php\/product-category\/wrist-watches\/quartz-watches\/\">quartz wristwatch<\/a> in 1969.<\/p>\n<p>Seiko is widely known for its wristwatches. Seiko and Rolex are the only two watch companies considered to be <a title=\"Vertical integration\" href=\"https:\/\/en.wikipedia.org\/wiki\/Vertical_integration\">vertically integrated<\/a>. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko&#8217;s mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts internally.<\/p>\n<p>Seiko offers one of the widest ranges of watch technologies in the world\u2014<strong>quartz, kinetic, solar, mechanical, and Spring Drive<\/strong>\u2014spanning everything from affordable everyday pieces to six-figure haute horlogerie. Over the decades it has launched multiple global brands, including <strong>Lorus, Pulsar, and Alba<\/strong>, while elevating its prestige through innovations like <strong>Spring Drive<\/strong>, which helped push Seiko into higher-end territory. In the 2010s, <strong>Grand Seiko and Credor<\/strong> were separated into fully independent luxury brands, while Seiko&#8217;s own global lineup now includes <strong>Grand Seiko, King Seiko, Prospex, Astron, Presage, and Seiko 5 Sports<\/strong>, with Credor remaining primarily Japan-focused.<\/p>\n<p>Among Seiko&#8217;s key lines, <strong>Seiko 5<\/strong> (born in 1963) is the gateway mechanical series known for durability and value; <strong>Lord Matic<\/strong> defined 1970s style with faceted crystals and colorful dials; <strong>Astron<\/strong> remains Seiko&#8217;s flagship GPS-solar tech line; <strong>Presage<\/strong> focuses on traditional mechanical craftsmanship with enamel and urushi dials; and <strong>Prospex<\/strong> delivers professional-grade dive, field, and pilot watches often embraced by enthusiasts. At the top end, <strong>Grand Seiko<\/strong> emphasizes precision, Zaratsu polished design, and movements like Spring Drive, while <strong>King Seiko<\/strong>\u2014revived in the 2020s\u2014brings back sharp, elegant 1960s styling with modern calibres.<\/p>\n<p>Finally, <strong>Credor<\/strong> represents Seiko&#8217;s pinnacle of artisanal watchmaking, producing low-volume pieces in precious metals and showcasing Japanese decorative arts and haute complications from the Micro Artist Studio. Beyond watches, Seiko has also produced various electronic devices and, historically, jewelry and eyewear\u2014though those divisions have since shifted to other companies.<\/p>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;146271&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][vc_single_image image=&#8221;146270&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_masonry_media_grid css=&#8221;&#8221; grid_id=&#8221;vc_gid:1782474888585-f2da782a-8444-2&#8243; include=&#8221;146307,146308,146314,146312,146311,146309,146313,146310,146316,146315&#8243;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Vintage 1967 Seiko Business-A (ref. 8346-9020) automatic watch with silver sunburst dial and day-date display<\/p>\n<p>MADE IN JAPAN!<\/p>\n<p>This watch ships from \ud83c\uddfa\ud83c\udde6Ukraine with tracking number<\/p>\n","protected":false},"featured_media":155916,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[566],"product_cat":[544,546,21],"product_tag":[1341,1346,48,258,259,1344,1342,1345,777,1343],"class_list":["post-163455","product","type-product","status-publish","has-post-thumbnail","product_brand-seiko","product_cat-duty-free-but-with-more-kgb-surveillance","product_cat-seiko","product_cat-wrist-watches","product_tag-1960s-seiko-automatic","product_tag-jdm-vintage-watch","product_tag-mechanical-watch","product_tag-pre-owned-watch","product_tag-second-hand-vintage-watch","product_tag-seiko-8346","product_tag-seiko-business-a","product_tag-seiko-mechanical","product_tag-vintage-japanese-watch","product_tag-vintage-seiko-day-date","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"exclude_global_add_ons":true,"addons":[{"name":"Add Seiko lug width matched leather straps with 20% off:","type":"multiple_choice","position":0,"required":false,"title_format":"heading","default":"0","description_enable":false,"description":"","placeholder_enable":false,"placeholder":"","display":"images","restrictions_type":"any_text","adjust_price":false,"price":"","price_type":"flat_fee","restrictions":false,"min":"0","max":"0","options":[{"label":"leather strap for Seiko - Blue","price":"16.95","price_type":"flat_fee","image":146284,"visibility":true},{"label":"leather strap for Seiko - Black","price":"16.95","price_type":"flat_fee","image":146318,"visibility":true},{"label":"leather strap for Seiko - Light Brown","price":"16.95","price_type":"flat_fee","image":146286,"visibility":true},{"label":"leather strap for Seiko - Dark Brown","price":"16.95","price_type":"flat_fee","image":146285,"visibility":true}],"id":1782485480},{"name":"Add Gift Box:","type":"multiple_choice","position":1,"required":false,"title_format":"heading","default":"0","description_enable":false,"description":"","placeholder_enable":false,"placeholder":"","display":"images","restrictions_type":"any_text","adjust_price":false,"price":"","price_type":"flat_fee","restrictions":false,"min":"0","max":"0","options":[{"label":"Leather Travel & Display Case - black","price":"21.95","price_type":"flat_fee","image":96401,"visibility":true},{"label":"Leather Travel & Display Case - brown","price":"24.95","price_type":"flat_fee","image":96400,"visibility":true},{"label":"Lacquered wooden box with pillow with 20% discount:","price":"27.95","price_type":"flat_fee","image":39850,"visibility":true}],"id":1782485481}],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Vintage 1967 Seiko Business-A 8346-9020 Automatic Day-Date Watch | Soviet Watch Store<\/title>\n<meta name=\"description\" content=\"Original 1967 Seiko Business-A ref. 8346-9020.
