Looking at a couple different Fathom Series (OO9171-15) pictures and I've noticed the SKU is printed on the inside left arm on one and the inside right arm on another. Is one a fake or is this normal? Thanks for your time!

At O Stores, I've see both versions plus ones with no printed markings at all. It's odd how they did the printed markings on them; I've seen, on the right earstem, the markings printed in different positions as well (one closer to the top of the earstem and one towards the bottom)

Thanks Oak... You think they would've stuck with one area to make simple and clear cut:)
