I bought a BB58 from DavidSW as I was told they were very legit (buy the seller and all that) and had a great experience myself.

However, I just learned about superclones/replicas and am now paranoid. DavidSW has an authenticity guarantee but has anyone ever heard of them unknowingly selling a superclone/replica?

If I wanted reassurance, could I send it to Tudor for an inspection? Is it safe to assume if it was a superclone or replica they'd be able to tell and would notify me? Would they even service it if I bought it from DavidSW?

I bought it with the original box, 5 year warranty papers/card, booklet, and it has a serial number. But would a superclone/replica have this as well?

Is the model a "tell"? I bought it as a 79030N model. However, when I look up the same exact same Tudor on the Tudor site, I see it as M79030N - https://www.tudorwatch.com/en/watches/black-bay-58/m79030n-0002

What is the difference between 79030N vs M79030N?
