I got this new gwg 2000

I got this for my birthday a f I was so excited the moment I saw the serial number I knew it was the watch. It is my first ever mudmaster it's decent in comfortablility and looks pretty sick, the carbon forged resin looks good and the display is pretty clear. The thing I am very impressed by is it lume, it was 7 in the morning I was walking around with this one my wrist and the sun is not even bright and the watch is already glowing in the dark I am not sure if it is normal as I don't own that much watches with lume, but I had heard a lot of complaints about the new mudmaster is it really that bad and I have a question to ask is the new mudmaster tough and would the water go in if the crown is not srcew in properly
