From what I understand most of the date windows have been updated to more closely resemble the correct location. They still do not have the taper or the very small bevel around the edges. From my point of view the newest version attracts too much attention to the date window with its rather large bevel that comes to close to the 5 o'clock marker. Notice how much further away the date window is from the 5 o'clock marker in pics 1 and 3. I don't think that sanding the inside of the hole down will fix this problem 100% because the outside location of the bevel will still be located too close to the 5 o'clock marker. All in all both are great reps. In my opinion it just depends on how close to the original we want our watch to be and what factors are most important to us.
