Newbee here........Thanks to all the valuable info here, I bought 3 economy Rolex's from Silix, all beautiful! Exceeded my expectations! The movement on one of the Submariners worked when I first received it, but when I went to wear it for the first time 3 days later, it quit working.....won't move at all.......emailed Michele today. Will wait for instructions on what do do. I have faith Michele will take care of it. Anyone had similar defective movements?
