This used, authentic Citizen Tsuno Chrono made in Japan is fully inspected and prepared for fast shipping, offering a distinctive chronograph design highly sought after by collectors.

This watch is an updated version of Citizen’s first full-fledged chronograph, the “Chronograph Challenge Timer” introduced in 1973. Known affectionately as the “Tsunochrono” for its push buttons positioned at the 12 o’clock side of the case, which resemble small horns, this iconic model stands out for its unique design. Unlike conventional watches, its off-balance proportions, soft case shape, and sharp bezel combine to create a distinctive and harmonious aesthetic.

The 38.0mm case sits comfortably on the wrist.
