Cal. 32 is a mono pusher chronograph movement with no counters produced by Landeron (Charles Hahn & Cie.) in the 1930s. The design is entirely different from all other Landeron movements, with the balance on-axis with the winding crown, and one of the only movements ever made with the column wheel at 9:00 along with the stem. Measuring just 12.75 ligne (28.70 mm) diameter and 4.45 mm thick, watches using Cal. 32 are extremely small.
