I have a couple watches that need new batteries. They're quartz TAG-Heuers. They're supposedly good for 200m water resistance. If I have the dealer send it back to the "factory" for the battery change plus the appropriate pressure testing/sealing, they're supposed to be good for that 200m rating. It also costs some $50 and 2 weeks for a battery change. But if I just take it to a local jeweler and have them change the battery, it's a few minutes and a few bucks. But obviously no 200m water resistance assurance.

We don't need 200m water resistance. But for just swimming in a pool or at the beach, can the mall jeweler battery change be trusted? I don't want to wind up with a foggy watch.
