ZENITH Sporto Cal. 120-T

ZENITH cal. 120-T in heavy steel case (with long lugs). The movement features the famous seconds-stop mechanism, which means that the watch stops running when the crown is pulled out. The cal. 120-T differs from the 120 by the steel movement, other than brass. It also has a fine regulation mechanism on the balance. Cal. 120-T was produced in a batch of 18.000 between 1961 and 1963. The movement is, like the Cal. 135, engineered by Ephrem Jobin.
The watch has been recently serviced by us.
