Ceva istorie: "Business: (Sub-brand) - ( aka Bell-matic and Business A) The Business brand was used on a few Japanese market Bellmatics during the late 1960s, which were powered by the 4006 Bellmatic caliber (Business Bell) and the 27j 8306/46 Seikomatic caliber. This sub-brand seems to have been part of a short marketing campaign intended to emphasize the attractiveness of Seiko watches to the Japanese 'salary-man'. "
