This is my second black dial Shanghai A581 made in 1959. This one is in much better condition than my 1st black dial A581, It has no date numbers on the movement so it was made in 1959. Black dial A 581 usually cost 3-4 times more than a white dial Shanghai A581.
Now there are many repainted black dial A581s for their higher prices, so beware of these non-original black A581s.
