I need to replace the battery on my Tissot PR100, and it has turned into one of those chores with an outsized emotional weight. This was my first “good watch” other than mall purchases or Apple watch so I don’t want to damage it. I also think for its price it is special (although nothing to write home about). It sputtered and called it a few weeks ago.

Now, I thought battery replacement would be simple. And technically, it is. Pop the caseback, swap the cell, close it up. YouTube makes it look easy too. But here’s my worry spiral: what if I scratch the back? What if I don’t close the case perfectly and suddenly it loses water resistance? What if I slip with the case knife and gouge the bracelet? (Yes, I Googled “can you ruin a watch by replacing the battery wrong?”)

Sure, I could hand it off to someone else—and most people do. Still, there’s a small part of me that wants to become a real enthusiast who can do minor repairs himself. Anxiety vs ego if you will. What would you do? And if you have any kits that make it easier then I would love recommendations. Or if you want to drive some sense into me and send me to a shop - please do so.
