Hi there I too have the exact same clock as you but I have all the original paperwork and to quote from it re winding - To wind the clock, set the key firmly on the squae winding post extending from the rear of the clock. Turn the key in a counter-clockwise direction until you feel you cannot wind it further.
If youd like I can send you a photocopy of the paperwork I have.
