- CITIZEN RECORD LABEL RECORD LABEL TSUNO CHRONO Specified stores handling model Cal.0510 AN3660-81A Men's
This is an update of the "Chronograph Challenge Timer," which was introduced in 1973 as Citizen's first watch with a full-fledged chronograph function. This iconic model has been nicknamed "horn chrono" because the push button placed at 12 o'clock on the case looks like an antler. Unlike ordinary watches, the balance that deviates from the theory makes it stand out for its individuality, and the soft case shape and sharp bezel are in harmony with each other to create an exquisite design. The case size is 38.0 mm, which fits comfortably on the wrist.
