ZENITH Cal. 120-T
The successor of the ZENITH Cal. 120 is the 120-T. Just like the regular 120, this movement can lock it’s seconds hands with a brake-mechanism under the dial. The seconds-stop is activated when the crown is pulled out.
The 120-T has the same construction as the 120 but differs in a few ways; the screw-balance wheel was replaced by a more modern ring-balance. Also the compass of the 120-T has a movable construction that allows the spiral block carriers to move (chronometer adjustable). The movement is nickel plated.
