Tsuno Chrono

Citizen brings history forward with a reintroduction from our iconic Challenge Timer collection. In late 1972, we conceptualized an automatic chronograph with a “bullhead” construction, with the crown and chronograph pushers located at the top of the case. This model later resulted in the launch of the Tsuno Chrono, Japanese for “horned chronograph,” in early 1973.

The new Tsuno Chronograph Racer includes a hand-assembled movement featuring our signature Eco-Drive technology. With that beloved bullhead structure In a 45MM case, the watch has a 1/5th second flyback chronograph, tachymeter, alarm, date, luminous hands and markers, and is completed with beautiful domed sapphire crystal.
