Recently picked up a 2019 Rolex Explorer 2 box + Papers from a reputable dealer. In looking at the watch it I notice that there appears to be uneven lume applied to the the 12 o'clock triangle. The area in the middle of the triangle is darker, grayish in regular light and doesn't glow as brightly in the dark as the rest of the indices. I have attached photos but it is difficult to see in pictures. It isn't difficult to see via the naked eye though and I have had a couple of people tell me what I am seeing is there, and that I am not losing my mind. I didn't take a loop to it because frankly I would never look at the watch through a loop so why get that picky? I am curious thoughif this is something to be concerned about or if this is somewhat normal? I tried to research it a bit and I see references here and there to uneven lume application but in the pictures I have found it looks much different from what I am seeing in my exampe.
If you look at my attached images I would look at the lume photo first for the darker area and then look at the non-lume photo and I think you will be able to sort of make out what I am talking about
