1979 Citizen Octagon BullHead Challenge Timer ref. 67-9356, also known as Bullhead, Easter rabbit or Mikey Mouse. Automatic fly-back movement cal. 8110A. 38 X 41mm. case.
The movement is automatic with hand winding capability, 23 jewels beating at 28.800 bph, fly-back function with column wheel and day and date indicator. The fly back function means that you can reset the chronograph while in motion and it will start again without needing to go the entire process of pressing stop-reset-start. So, one push can do all of this. How do Citizen do it at this price?
The word bullhead is the term used for chronograph watches that have their crown and chronograph pushers on top of the case (in some cases the crown is at the bottom of the case) rather than on the side – hence resembling the look of the head of a bull with its horns. These cases are usually larger and thicker than the average chronographs. Most of the time their cases are not even-shaped, meaning that the top of it where the pushers and the crown is located is wider and thicker and the bottom of the case is thinner. This way the dial is tilted towards 6 o’clock. This allows the wearer to check the time on the watch much more easily hence the oddity of the case. They are particularly special for no reason other than in most cases they were produced in relatively small numbers.
