Returning Watch After 2 Weeks?

So my 38mm Apple Watch came today. I also placed an order for the 42mm but thats still processing. My question is, would apple give me a hard time if I choose to return it two weeks later? I bought the stainless steel model so it is almost impossible to avoid little micro scratches. This isn't like a laptop where its aluminium and is resistant to scratch. Laptops can still look new after two weeks. I bought the stainless steel with sports band so Im sure oils are going to transfer onto the band during my two week trial. Just don't want to be stuck with the watch if I decide the 42 is for me.
