any recommended loupe to buy an from where?

[newbie09]

I bought one loupe from Daiso, 7X since can't find 10X. Examined (just for the fun of it....) my SD and spoted the tiny laser-etched Rolex Coronet Signature at the 6 o'clock position on the Sapphire Crystal......in 5seconds

Just curious, would the tiny laser-etched Rolex Coronet on the Sapphire Crystal is good enough to tell it's not a fake rolex?

Nope, even the fake in Vietnam has it... Is just the quality of the signature that is different.
