Watches with this movement

You may see the term “Wehrmachtswerk” being used to describe watches with the Unitas 6325 movement. Watches with these movements go back to WWII, however, just because a watch has a wehrmachtswerk movement doesn’t mean it’s that old. The movement pictured on this page was found in a vintage BWG Swiss Courage timepiece likely produced in the 1960s.

The 6325 can be found in a variety of other vintage military watches as well. As for the terms “wehrmachtswerk”, there are no direct English translations provided by Google translate. When breaking up the word as suggested by the translator, “wehr macht” in German means “fight back” or defense (at least according to Google).

I own a Bungoia Precision of the 70`s with a UT 6325 in it. Extremely precise

A lot of swiss “microbrands” made almost exclusively for the ex-yugoslav market used this movement. Just with their name stamped on. Two examples I am very sure used it, were for example brands Darwil and Omikron (probably also Marvin and others).

Rainer Nienaber used these movements in some of his watches.

Can someone state how accurate are this movements? I have one old granpa’s Omikron with so scrathed up crystal that I can not even read how many jewels it has 17 or 21. The amplitude should be somewhere 250ish?

The (almost) cadence of the rotor behaviour, so to speak, really intrigues me and the sound of it never gets old, imho

Own 3 BWC Courage’s with this movement, black, golden ant white. Other BWC black military style with AS1130 movement, and a BWC Buffalo with ETA 2853 movement. Really precise all off them.
Glad to find this corner .
