Not sure who this question is for, but I was told I would have to pay a polishing fee of $100, or so, because I wore it out of the store. I was contemplating exchanging my 17 for 18, but now have decided that 17 is my perfect fit. If you think you may want to exchange yours, and are wearing it, I recommend you protecting it by wearing a wrist sweat band.Hey how much did they say the fee was because I have a little worn in mine but it hasn't been 30 days and I want to go exchange for the 17
