I'd recommend you simply take the watch to a reputable jewelry store. A local jewelry store may even have an actual watchmaker on site. Call up a few in your area and ask if they do. They'll replace the battery for probably $10-$15 (they do it at the local "Bands & Batteries" store here for approx $8). If you do it yourself you'll probably impair its water resistance or perhaps scratch the back of the watch case. Not worth the effort to save 10 bucks in my opinion.
