I have a 45mm narikaa PO, nearly the same thing happened to mine! NO, I didn't wear it at work as a shark dentist!! I honestly belive that the po I have, is just not saphire. none of my other watches have any issues like my PO! I'm sure noone announces sapphire when actually mineral on purpose. especially a seasoned guy like narikaa! but I'll give it to ya, that I have thought many times, that it is wierd this one watch in particular scratches up as easy as a frosted doughnut.....
