The Tissot caliber 27 was released in 1936 and produced until 1949 in Switzerland. Following 1949, many variations were introduced and manufactured until about 1961. The movement pictured here is a caliber 27 without an anti-shock system. We previously posted this caliber 27-1T which is the same movement with an Incabloc shock system. The 27-1T was produced in between 1950-1952.
The movement pictured above is from a Tissot Antimagnetique watch.
