Bullhead

The Citizen Bullhead puts its crown and chronograph pushers above the dial, giving the watch its name—and keeping the controls clear of your wrist. That unmistakable layout connects the compact automatic chronographs of the 1970s with later quartz and light-powered versions, but the watches beneath it differ considerably.

Vintage references such as 67-9011 and 67-9020 belong to the mechanical side of the family. Citizen’s 8110A combines automatic winding, a day-date display and a flyback chronograph: the running stopwatch can be reset and restarted with one press. Three registers handle elapsed minutes, elapsed hours and running seconds, packing a substantial amount of information into the dial. Case outlines, dial treatments and dimensions vary across the vintage range; “Bullhead” describes the arrangement, not one fixed specification.

Later Tsuno Chrono and Tsuno Racer models revisit those top-mounted controls with quartz or Eco-Drive technology. Their generally larger cases give the layout more breathing room, while the light-powered versions exchange the vintage rotor and mechanical flyback mechanism for a rechargeable cell.
