That photo was retouched by soviet propaganda. They "cut off" little too many robbed watches that soldier had on his forearm... Yeah there's stories that soviet soldiers often start conversation with "davay chasy!" what mean "give me watch!".
This photo might have been touched up it is not the soviet version. The soviet alterations show the man holding on to the other flag bearer is wearing no watches at all. You can see a comparison in the links below.
