Depending on when you bought your Timex, you shouldn"t need a battery just yet, your Timex came with a good battery. Look under the stem (winder) for a small piece of plastic that is not allowing the stem to go all the way down, remove that piece of plastic and push the stem down and your Timex will start. Or if your Timex has buttons, look for a tab of plastic on the back cover, this tab of plastic is keeping the battery from (ground) a complete circuit remove this tab of plastic to start your Timex. Changeing the battery while fairly easy, you"d need jewelers screwdrivers and of course the new battery, Best Bet, look for a small watch repair shop in your area for the battery change.
