Picked up a cool vintage Seiko chrono from a friend and local collector today. His pics below. It's a brown Bullhead from 1974. A love it or hate it design but I have always thought they were as cool as hell, and a welcome relief from the unrelenting sameness of the majority of contemporary chronographs. The movement is built like a tank, and has the features (column wheel / vertical clutch) generally only found on higher end contemporary movements.
