From the closeup, i can see that the date window actually 'eats' part of the lume on the 3 marker. I dun think this is poor qc, poor placement of the date window is more likely. 
Sorry guys. The picture that I took didn't do justice to the problem that I mentioned about the lume on numbr "3". Let me try to desribe to you what is actually on the dial. From the picture, you can see the uptick (at downtick) of the ends of the number 3. This is not lumed but the tracing line of the number "3". Instead of following the tracing line, the painter of the lume (here I assume is is done by hand, it could be done by a robot), the ends of the the lumed 3 stops at the edge of the date window. In fact, it should continue on. Now, what you see is the plain white tracing line of number "3".
Interestingly, the ends of the lume for number "9" looks similar to the ends of the number "3".

This could mean that the font used for the painting of the lumes is consistent. If that is the case, it could only mean that the font used to trace the number "3" is inconsistent with the rest.
Anyone who owns a Aristo also have the same observations?
