This Seiko Chronograph Automatic "Bullhead" Ref. 6138 is an iconic vintage timepiece, renowned for its distinctive case design, where the pushers and crown are positioned at the top, resembling a bull's head. Released in the 1970s, it is powered by the Seiko Caliber 6138, a robust and reliable automatic chronograph movement with manual winding capability and a column wheel mechanism. Its 42mm stainless steel case is designed for ergonomic comfort, sitting securely on the wrist. The striking brown sunburst dial features dual sub-dials for 30-minute and 12-hour counters, complemented by a tachymeter scale for precise timekeeping. Luminous hands and markers enhance legibility, while the rubber strap ensures a sporty yet elegant look.
