on 8/24/2009 WARNING: Changing a watch battery requires special tools and knowledge. You can very easily turn your expensive watch into a piece of junk that will need to be repaired by a professional at a much higher cost than the $10.00 it costs to have a battery professionally replaced. Trust me I know. :(
