The Dugena 874 is a mechanical watch movement that was produced from 1937 to 1970. With over 3.5 million units manufactured, it featured various interchangeable chrono mechanisms, allowing for series with parts from different calibers. This manual-wind chronograph movement includes functions such as a 60-second counter, as well as 30 and 45-minute counters that are switched by a cam. It also includes a sub-second dial and a date complication positioned at 6 o'clock, which can be adjusted by approximately +/-24 hours.
