Problems with my first Rep - VSF stops randomly

Hi, doesnt anybody have experience with recieving a faulty watch. i recieved this AT Worldtimer Saturday and i do love the look of it, but it has a problem it has stopped randomly while wearing it. and the only way to get it started again, is to pull the crown out and set the time, and put it in again. even if i shake it up it doesnt start up, so i dont think its because of low power. More like the hacking activating for no reason. But nights it also stopped some hours after i put it down. That could be power reserve, but you should expect more than some hours right? even for a replica. Does anybody have experience with this, i normally tinker with watches myself. So i dont have a watch guy i can trust with a Rep. I bought it through Andrew (Trusty) and he say there is 6 month Warranty, so i can send it back to China for repair, but there is no protection or anything, if it gets taken in Customs. Does anybody have experience with that. i dont know if i should just keep it, and try to fix it myself ?
