Brand: Seiko Model: Business-A Reference Number: 8346-9010 Serial Number: 7419205 Movement: Automatic Caliber 8346A Dial: Silver sunburst dial with applied faceted indices, showing light, even vintage aging Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1967 Condition: Good vintage condition with honest signs of wear Dial and Hands The silver dial features a subtle sunburst finish that plays beautifully with the light, complemented by applied, faceted baton indices with black central striping for enhanced legibility. The applied "SEIKO" logo sits proudly at twelve o'clock, while the "BUSINESS-A" and "DIASHOCK 27 JEWELS" text is crisply printed above six o'clock. A framed day-date window is positioned at three o'clock. The dial shows a light, even vintage patina consistent with its age, maintaining a clean and attractive overall appearance. The sharp, dauphine-style hands exhibit minor signs of aging but remain highly legible and structurally sound. Case and Crystal The 37mm stainless steel case displays the classic, angular lug profile characteristic of Seiko's design language from this period. The transition between the polished bezel and the brushed lug surfaces remains visible, though the case shows honest signs of wear, including surface scratches and minor handling marks typical of a watch that has been enjoyed over decades. The domed acrylic crystal is clear, offering an unobstructed view of the dial, with only faint micro-scratches visible under close inspection. The screw-down caseback is well-preserved, with the reference number (8346-9010), serial number (7419205), and "WATER PROOF" markings clearly legible. Movement Powering this timepiece is the Seiko Caliber 8346A automatic movement, featuring 27 jewels and the Diashock anti-shock system. The movement components, visible in the provided images, appear clean, with the rotor clearly signed "SEIKO 27 JEWELS." Performing well within expected vintage tolerances; running strong and steady. The timegrapher results indicate a performance of +30 to +38 seconds per day. Strap The watch is fitted with a black leather strap featuring a crocodile-grain pattern and contrasting red stitching. The strap is secured with a standard stainless steel pin buckle, complementing the vintage aesthetic of the timepiece. Condition This Seiko Business-A is in good vintage condition. The case shows normal wear with moderate handling marks, while the dial presents a very attractive, even aging that adds to its vintage character. The movement is clean and operational, and the overall presentation is highly appealing for collectors of mid-century Japanese horology. Dimensions Case Size: 37 mm (excluding the crown) Remarks This Seiko Business-A is a testament to the brand's ability to produce refined, reliable, and aesthetically pleasing timepieces for the professional market. Its combination of a sophisticated dial, sharp case lines, and a robust 27-jewel movement makes it a versatile and historically significant addition to any vintage watch collection. History Introduced in the 1960s, the Seiko Business line was specifically targeted at the growing demographic of white-collar professionals in post-war Japan. These watches were designed to be elegant enough for the boardroom while offering the durability and precision required for daily wear. The "Business-A" models, often featuring higher jewel counts and sophisticated automatic movements like the 83-series, represented a premium offering within this segment, bridging the gap between standard dress watches and the higher-end King and Grand Seiko lines. / Second Vintage SKU: SEI-BJX-0002
