Remarks The Seiko Business-A holds a special place in the brand's lineage as a bridge between the standard utilitarian models and the higher-end King Seiko and Grand Seiko lines. The "Diashock 27 Jewels" inscription on the dial proudly advertises the high-spec movement within. This specific reference is particularly desirable due to its black dial configuration, which is often harder to find than the silver variants. It is a stylish, historically significant timepiece that captures the essence of the "Salaryman" era in Japan. History Introduced in the mid-1960s, the Business-A series was marketed towards Japanese office workers who required a reliable, accurate, and stylish timepiece for daily wear. The use of the Caliber 8346 was a testament to Seiko's commitment to quality mass production, utilizing a movement architecture that was both thin and durable. The 8300 series movements are respected by collectors for their integrated automatic winding mechanism and high jewel count. This specific example, dating to October 1967, was produced during the golden age of mechanical watchmaking in Japan, just prior to the quartz revolution that would change the industry forever. / Second Vintage SKU: SEI-SBJ-0008
