Brand: Seiko
Typology: Vintage chronograph
Year: 1976

We’re not breaking any new ground here in explaining that a Bullhead chronograph gets its name from the orientation of its crown and pushers. Notably, the controls sit atop the watch instead of the more customary right side of the watch. Apparently, the rationale for this placement is to avoid accidental engagement of the pushers. 
Also, a Bullhead seems to ape the typical look of a dash-mounted timer, so it’s likely that these atypical chronographs were created for use in motorsports.

The Seiko Bullhead was produced in 1973, principally, in two dial variants. The black/blue version seen here was made alongside a brown/gold edition. Both models were sold until 1979, which also happened to be the last year of production for the automatic chronograph movement, the 6138.
The bracelet is called "Fishbone” due to its central “spine” of vertical links that sprout a network of horizontal “scales”.

A close look at the Seiko Bullhead dial shows the typical attention to detail by the Japanese brand.
The Seiko Bullhead easily ranks as one of the firm’s most popular vintage watches and it’s also one of the rare models that can often by found in a Swiss chronograph collector’s portfolio.

This "Bullhead" is J market, so made in Japan, in March 1976 and is in splendid shape.
