COLLECTOR’s NOTE
Introduced in 1973, the Citizen Challenge Timer marked the brand’s first full-scale automatic chronograph and showcased the innovative Caliber 8110A, a high-performance in-house movement featuring automatic winding, manual winding capability, quick-set calendar, and flyback chronograph functionality. Its unconventional Bullhead configuration was achieved by rotating the movement 90 degrees, placing the crown and pushers at the top of the case without compromising functionality—a design that has since become one of Citizen’s most recognizable creations.
The highly sought-after Panda dial further enhances its collector appeal, offering a striking contrast between the main dial and chronograph registers while perfectly complementing the bold case design. Today, the Challenge Timer Bullhead is widely regarded as one of the greatest Japanese vintage chronographs, admired for both its technical significance and unmistakable 1970s character.
