The Seiko Bullhead 6138-0040 was introduced in 1969 as part of the “Seiko 5” family. According to Seiko’s official website, the “5 Sports” line came to be known as such because of five defining traits. These attributes are automatic winding, day/date displayed in a single window, water resistance, recessed crown at the 4 o’clock position, and a durable case and bracelet. Condensed into affordable, high-performance watches, they came in different guises aimed at a younger generation with very active lifestyles.
