The Kasper 952 watch movement is equipped with manual wind and features a sweep second hand and a date function. It belongs to the 13''' size category and was commonly used around the 1960s. The winding mechanism can either be rocker-bar or clutch, with variations including the absence or presence of a setting-lever spring and the placement of the ratchet. The movement has minor modifications on the base plate as denoted by the model numbers 901, 951, and 952.
