Service Manual TIMEX Model 33

self wind day and date 13 lig. 28.96mm 1.140 in. The Model 33 movement is a 13 ligne serf-winding movement with day and date features. The Model 33 utilizes the same basic construction as the Model 31 except that a day and date mechanism has been added. A planetary gear winding system located on the Front Frame provides a compact method of obtaining the necessary gear reduction between the self-winding weight and the mainspring. The reserve power of the mainspring when the watch is worn by a normally active person is sufficient to run the watch for a full day. The day and date mechanism is similar to that used in the Model 27 .
