Hi everyone! I wanted to ask for some help because I decided to restore a heavily scratched Casio Vintage crystal after watching a bunch of tutorials, but I’m not getting the result I expected.

What I did:
I sanded it using 180, 240, 600, 1000, 1500 and 2000 grit sandpaper.
Then I cleaned the surface and used Polywatch with the cloth that comes with it (I’m from Argentina and the small tube costs almost 50 USD here, while abroad it’s like 6 USD 😅).

The problem is that it still looked kind of cloudy/blurry instead of fully transparent. So I tried using cerium oxide with a rotary tool (I think this might have been my mistake). I still couldn’t get a glossy transparent finish.

After that I sanded it again and even tried toothpaste polishing. It looks a little better now, but it’s still somewhat hazy and not crystal clear.

Can anyone help me improve it or explain the process that works best for you? As far as I know, most Casio Vintage models use acrylic crystals, right?

At this point I don’t know if I should keep polishing or if I already damaged the acrylic 😅

Thanks a lot for any advice!

Hey everyone,

I’ve been getting into Casio F91W mods and I’m trying to understand how people achieve those clean custom faceplates (like anime, brands, etc around the display).

(I want to make something like this: )

I already know how to:

open the watch
remove the module

But what I can’t figure out is:

👉 How do you remove the original faceplate (the printed layer under the glass)?

From what I understand:

it’s glued to the crystal
and not meant to be removed easily

I’ve seen some people say you can:

heat it with a hairdryer / heat gun
or push it out from inside

But I’m not sure what actually works without damaging the watch.

For example, I found a comment saying:

“You have to heat it enough to loosen the glue… it’s glued on pretty well”

And another method mentions heating + pressure until it “pops out”

Also saw someone suggest:

disassemble, clean faceplate, print reversed vinyl and glue it back

My questions:

Is removing the original faceplate actually necessary?
Do most people:
- remove it completely?
- or just overlay a new design behind it?
What’s the cleanest/pro method?
Any videos showing actual faceplate removal (not just module)?
Is it even worth it or too risky?

I’m trying to achieve something like:

custom artwork around the display
clean factory-like finish

Any tips, guides, or videos would help a lot 🙏
