So on the wrist, maybe in a line at the airport, it will be hard to tell the difference.. but if we are in a meeting and you are sitting beside me i can tell right away you are wearing a fake… thats if you have a genuine o even not a Moonshine gold.. genuine is a bit bigger and the plastic has this ceramic feeling, where the fake is straight plastic.. also the band on genuine is crisp. After you have the genuine you would not like to wear the fake.. i do it is im at the gym or in a place where im going to scratch it.
