Not to comment either way - but it is interesting that your customer has only ever left one feedback and that was the neg to you. It appears that he/she views feedback as a weapon to be used against sellers when he/she doesn't get his/her way.
Your auction does read that the watch is guaranteed to be working but I believe you are within your rights to expect the customer to accept a replacement. Combine that with the complaints regarding S/H, which is very clear in your auction, and it sounds an awful lot like a little bit of buyers remorse creeping in. I'm not sure how much of an opportunity the buyer gave you to correct the situation but, IMHO, once the feedback is placed the transaction is closed.
If you feel the buyer was totally unreasonable, it would be more than accurate to forewarn other sellers in the form of a neutral or neg.
Cheers!
