Hello all I am a new to this forum and am hoping someone here can give advice. I puchaced a replice IWC 3717 watch with an automatic movement a few months ago. There were a few flaws, such as the lume one the minute hand being thin on one side, but over all I was happy for the price. After a month of use, while setting the date, some piece inside froze and broke, and now when the crown is in the date set position, it spins freely. As it was puchaced on line, and is a replica, I doubt I have any recourse other than having it fixed, if its worth the trouble. My question is, is it worth the trouble?
