Seiko Watch Back Removal Tool - Used to replace your battery!

thingiverse

I recently got my hands on a Seiko watch after inheriting it from someone, but unfortunately, the battery had died. Since I live far away from any authorized Seiko dealerships, I headed straight to YouTube to figure out how to safely open up the case and replace the battery myself. After watching a few videos where users used hammers and screwdrivers to pry open the back of their watches, I knew there must be a better way! I'm not sure if this method will work for all Seiko watch models, but it worked like a charm on my 7T32- model. To remove the back of your case, simply align the nobs on the tool with the notches in the back and turn counter-clockwise to loosen, then clockwise to tighten when you're done.
