I recently bought this awesome piece. One of the things that led me to buy it is that I absolutely can’t find anything about this product online! All I know is that it has a 193 module, it’s made in Japan, it seems to be from the 80s, and it came with its original box and manual.

Do any of you know anything about this product? Is it really a collectible relic?

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!
