I heard there was a real watch with this error on accident. They had a video of it on YouTube. The video didn't look photoshopped to me (but I'm no forensic photo/video expert). When you make around a million watches a year (some say more, some say less) it's understandable if one just happens to make it through quality control. Generally though, quality control is now using machine learned intelligence cameras. So I'm a little surprised this could've escaped. As an individual who has worked for a manufacturing company I am familiar with Quality Control processes. I envision Rolex would have a system like this: A camera would inspect every watch, it would catch the inconsistency with this watch, the computer has learned what is normal and what isn't normal, the computer would red flag it, have a photo with a circle of the area in question and subject the questionable piece to a human quality control check. Thus, it's unlikely that this watch would pass quality control, by computer and by human, but it's not impossible. The future suggests that cameras will even be used to authenticate watches in the future as they will measure distances and thicknesses of the bezel, dial numerals, dial indices, etc. and compare them to the established template as a check for authenticity.
