This tool helps you open up your watch if you want to do some cleaning or other maintenance like I had to do.
I needed it to fix my automatic winding mechanism in my watch (Fossil ME3181) but did not have the tools available, so after a quick measure and modelling, this tool came out.
You might need some strength to clamp this tool tightly between your fingers, then press and turn simultaniously. I got it open, so you might as well. :-)
I only have a ø42mm version which fits this exact watch, but might fit other watches of ø42mm.
Be careful with reassembly of your watch. Weather/Water tightness might be compromised. I am in no way responsible for any damage.
