Rare WW1 German Pocket Watch Case with Nice Silver Antique Key Wind Pocket Watch

  

Rare WW1 German Pocket Watch Case with Nice Silver Antique Key Wind Pocket Watch. The little second hand is missing.

I tried to wind it with the key but it's tight and i don't want to force and damage the watch. See photo for measurement's. The Item in this lot is in used condition.

It's old so has some wear and discoloration due to age and everyday use.
