The Dugena 3358 watch movement, used during the period of 1968-1972, features a Triovis micrometer regulator for precision timekeeping. Its low profile is achieved through the integration of an indirectly driven minute and automatic gear into the movement. Additionally, it incorporates a ratchet on the dial side, a crown mechanism with rocker bar, and a rather small rotor ball bearing. While the specific differences between the 404 and 405 models are not known, the Dugena 3358 movement offers a range of functions including automatic winding, a sweep second hand, day and date displays, with the ability to set the day by changing between 18-24 hours and the date through quickset functionality.
