Handpolished Casio F-91W Backplate!

Mon, 3 Nov 2025

This is a short one, just wanted to share a little thing I did.
I handpolished the backplate of my daily, oil filled Casio F91W to a mirror.
I went from W20 all the way down to W0.5 diamond polishing/grinding paste by hand. It was kind of crazy how much effect the step from W1.5 to W0.5 had. It was kinda from "yeah this is a mirror finish" to "holy shit it's actually a mirror!".
The idea was to polish the surface so it would slip a bit less on my arm and feel a little nicer, since I am very sensitive to touch.
Both goals were fulfilled for sure :3

Here are some images (my first images in a blog, I hope it goes well, I tried to keep them all below 500kB!):
