The lume picture seems a bit odd to me because the bezels 12 oclock triangle should be the same color as the numbers on the bezel. The hash marks on the bezel should not be lumed but they appear to be a similar color to the lume on the dial.
I would need to see a non zoomed in picture to show more but it looks like the 50 and triangle on the bezel MAY have lost lume based on the first pic?
I don't have any UV pics of my sm300 saved but here is one I found online that hopefully shows what I tried to put into words. Also, as
@flqt-9000 pointed out if the UV light is shining while the photo is taken there should be a purple hue around the image. You can charge the lume quickly with UV and turn the UV light off and snap a photo and there will be no purple hue though.
