need help with selling my rolex to an unknown person

[realwhiz]

Hi there, someone contacted me about my rolex I'm advertising and wants me to meet him at his recommended watch store so that he can authenticate. I'm not sure if this is a scam, can someone recommend the best way to deal with a buyer in this situation? I'm concerned that he just takes off with it since it's not in a mall or the store doesn't have security.

thanks
