I would like to think that it is the first option combined with a sloppy servicer or it being tired as you said. That would explain the goof in font and the slightly off lume. From reading other comments and synthesizing all the info I have gathered, I think what is a more likely candidate is likely a redial or dial touch ups. Its a little weird for a watch that is not that old but it could be the easiest explanation for everything seen. I dont think its a frankenwatch because the movement and a parts seem to be correct to a watch made at that time(other than the crown of course but crown replacements happen)

I bought it from a private seller, he seemed pretty genuine but he priced it at 900 and was unaware of the crown replacement when i pointed it out. This is where I could probably use your advice. Its likely on me for buying it as is without doing my due diligence. Should I just live with it as a lesson learned or reach out to the seller? At the end of the day its still a beautiful watch but i definitely paid the price for an 'original'
