First of all, there are some watches that are over your head. And it doesn't take long to realize that.
But yeah, most watches use one of five or six batteries. 377 364 371 395 399 362 are the order I find most popular.
Just for fun. I find that many people choose watches that have the same battery inside without knowing. Maybe a price point thing I don't know. And also maybe you guys can confirm but many times the batteries die around the same time. One more observation, old people go through more batteries quicker. This is observation over time changing thousands of batteries. Odd eh?
Some pointers, if your going to do it yourself, use a clean cloth to do it on, while the back is off, why not clean the mating surfaces, it makes it easier to remote the case to the back. make sure your work surface is clear of everything, take your time, make sure you don't have to pee, and last but not least.......relax and go slow. If you get aggravated easily leave it to a pro, it's not worth saving a few bucks if your just going to ham fist it. I see that all the time. People think their smart then come in to my store only for me to quote $80 to fix the botched job.

Thanks for the tips.
