Wearing the watch for the first time
Before being worn for the first time, or if it has stopped, a Rolex watch must be wound manually in order to function correctly and precisely. To wind the watch manually, unscrew the winding crown completely, then turn it several times clockwise (turning in the other direction has no effect). A minimum of 25 turns is required for adequate partial winding. Carefully screw the crown back down against the case to ensure waterproofness. The watch will then be wound automatically as long as it is worn on the wrist.
