When I recieved the watch I read the instructions and followed them in accordance before attempting to wear the watch. Unfortunately the watch did not start. After calling and consulting with the local watchsupplier I wound it up a bit more, never fully to the end however. It did not start then either so I took the watch to them and they examined it and said that it could be stuck because of the lubricant used or a loose part and that I should contact the maker.
