I have owned this watch since 2012. The watch does not work fully but can be used for parts or repaired for use. The winding mechanism broke and needs service. One of the clasp screws broke but was repaired with a bolt. A copy of the buyers paperwork will be included from the time of purchase in 2012 for authenticity, less personal information. The watch is no longer under warranty but a paper copy of the warranty card will be included. The watch dial will turn but the winding mechanism does not synchronize to long time intervals, hence reason for repair is needed. See photos for details. I am disappointed that I have to let this go but am happy to assist any interested buyers with questions that are applicable for purchase. I have never opened the back of the watch, nor do I have any experience on doing so at this time.The box to the best of my knowledge is not orginal. It was the one sent to me with the watch. I hope this helps answer most questions but let me know if any others come up!
