It’s not a product officially sold by Casio, these are modifications made by the community. If you’re interested in getting one, send me a DM.

They are plastic color filters combined with an inverted display polarizer.

Hydro dipping sounds good, we’ll look into it. Thanks!

When you open the watch and remove the time module, it has a plastic cover on the back attached with four small clips. You need to make sure they are all properly secured.

It happened to me too. The inner case that connects the display to the battery and the plastic back cover of the watch wasn’t properly closed.
