If he's local, better to deal COD. If he's a foreigner, make sure that the monies was deposited into your account before you release the watch. Don't trust if the cheque's still in float pending clearance. I had a foreigner whom wanted to purchase one of my watches but requested it to be sent to his friend in some African countries. Sent me a picture of his passport to show that he was for real. I Googled and found that the passport picture was taken off a blogsite. Anyway, better to not reveal your phone no. in adverts as they would WhatsApp you endlessly with circumstantial excuses on why they had to transfer the monies here and there, bla bla bla. You block one no, they used another no. Not worth the trouble.
