Ump Ruhla Watch

Early post war, but period appropriate, men's wristwatch. It is in working order, although the face is a little dirty (it could be light corrosion). It seems to be keeping decent time. This has a great style face with the seconds dial at 6 and in black. It has a distinctive military style. This manufacturer made this exact watch during the war and it was advertised to military personnel. The only difference is the post war maker mark of the face and back. German watches were inexpensive and simple. This is essentially the equivalent of a WWII German Timex. It is what the average soldier could afford.

Note for handling watches:

• Do not shake a watch! If it seems to be sticking, rotate it back and forth a bit as if you were turning a knob off and on; this motion works in the same direction as the movement. 
• Never fully wind a watch! Wind the watch only until you feel slightly more resistance. If it stops turning, you've gone too far. You probably didn't damage it this time, but don't do it again. A better habit is to simply wind it a little bit throughout the day. 
• Generally speaking, as long as a watch still runs its probably still good. If a watch is a little slow or fast it can probably be adjusted with little effort. A watch maker can do it quickly with a timing tool but it can also be done with trial and error. Very often a small adjustment to the +/- leaver inside the watch will make a big difference to the speed.
