The Dugena 774S watch movement, also known as the Wehrmachtswerk (Germany Military Movement), is a manual wind movement with a sub-second function. It features an early fixed stud carrier that later became mobile. The base plate is signed with the number 6310, indicating its model designation. However, the specific differences between the 6310 through 6318 variants remain unknown, although they are likely related to varying bridge shapes. The Dugena 774S movement was used during approximately the 1960s.
