These are actual watches I have the opportunity to see in person. Ignoring the lighting, you can see one is matte and the other is glossy.
Can you confirm that indeed they are both KW ? !00% sure? Post up some better pics so we can get a better conclusion that both watches aren't mistaken for the same maker. Not saying i am disregarding your judgment. But you never know.
If they were indeed taken in the same light then why are the lumes different on the 12 marker? One is lighter than the other??????
If they are KW then I would say one watch was from an earlier batch. If i remember right my buddies 305 and 389 are glossy. So yes Glossy should be the correct lume.
Good Luck & God Bless
