Cal 120T

ZENITH manual movement cal. 120T. Basically the same as cal. 120, but it is fitted with a mobile stud holder, which helps centering the transmission stone. Cal. 120T is also nickel plated instead of gold. A special feature is the hack mechanism; the watch stops when the crown is pulled to time setting mode. This allows better precision when setting the time. 18 000 movements with this caliber was made in 1961-1963, this watch was finished in 1962 according to Zenith.

I love the simplicity of the black dial on this watch. I believe the dial might have been redone at some point. The watch runs and holds time well, and I got a new crystal fitted to really make it shine.
