The Citizen 5800 watch movement, utilized during the period of 1972-1974, incorporates a Triovis micrometer regulator and features a slide mechanism to release the stem. This movement is characterized by its electronically controlled balance motor, sweep second function, and date function that can be quickly adjusted by repeated pushing of the crown.
