The problem is datewheel hangup. More specifically datewheel hang. One will change and the other will get stuck. I actually went and talked to an AD after I had read about it because I was curious as to whether it was a rep thing. it's not. The gens have had problems too. Makes sense considering where the gen is made. And the white does look good too. But the black is the best. When you look at it the color actually looks sort of off black. In the 43mm. The 41mm is darker. Both are identical to the gen in appearance.
