All watches keep time. I have never tested the Pobeda's time keeping, but a full wind lasts over a day. Not sure on the model for the Pobeda either, think it may just be a dime-a-dozen model from the 80s.
The Duro has a scratch across the crystal between 12 and 1 o'clock. The date window does not set neatly in frame. The bezel is a little loose from the case on the lower half, and makes a small clicking sound when tapped.
