Seiko Bullhead chronograph

Legendary Seiko Bullhead chronograph, which you don't come across every day. There are small marks on the crystal, but the overall appearance is neat. There is a little patina on the edges of the dial, but the colors have remained bright. Case has marks from age and use and the Seiko steel bracelet is not the watch's original. Bracelet fits a wrist about 22 cm thick. Service history is unknown, but the watch works great. Date quick-set works, chronograph runs and re-sets well and the watch is running approximately +- 20 seconds per day.
