I've had the $200 Rolex Sub from Josh for about 10 months. For the last month, I've been having difficulty screwing the crown down. It usually takes a little while and I'm able to, but now it just spins and spins. I have a feeling something is stripped. I took it to a local watch repair shop, and he told me he couldn't get replacement parts because it was a replica. I was wondering if anyone here would be able to work on it, and roughly how much it would cost. Thanks!!!
