One day, he sold a piece of replica watchesto an American, John.After John received the watch, he found it didn't work and he immediately wrote an Email to Jack, which read "Hi, there. I have received the rolex replica. You said it is perfect in quality, but it didn't work here. Why?"Jack replied soon "Dear John, I am so sorry to hear that. Also please be patient , because of time difference,It's at night in Vietnam now, the watch is sleeping ."
