Great watch but maybe you should have posted in "WRUW" rather than "Help, Discussion and Advice" if you didn't want feedback. I too have a Seamster 300 without pinholes. I'm quite sure its the original lume but wouldn't bet on it. I'm not sure a copy of the original advert has enough definition to prove the case either way but i'm sure there are members of the forum who would know the "definitive" answer.
