O.k., this answer is very, very late in coming, but you press and hold the button on the right of the watch until the hands start spinning. Eventually they will stop near 12 o'clock. you then use the indented button the left of the watch to 'inch' the minute hand round to exactly 12 o'clock. Then press the right hand button again. The hands will now spin to the correct time in accordance with the radio signal.
What I want to know is how do I replace the battery?
