...and it passed them all.

I did that because in some of Amazon's reviews (not necessarily this watch), some users were skeptical about the authenticity of the watches (some actually were confirming that Amazon is selling fake watches). So, I ended up buying the watch anyway with the intention of doing rigorous research to see if it's authentic or not, and was going to return it if it failed the test.

I ended up keeping it because everything I read and watched online about how to validate a watch said this is the real thing.
