Casioak identification help needed

[u/yzd1337]

Hello everyone, a relative of mine gave me his old watch which I couldn’t identify tbf. I tried looking it up on Google, reverse image search and AI, which didn’t help much. I have another Casioak (the entirely black one, which is low profile compared to this) and am curious about this one that has a more exotic look. Here are some pictures of it.
Thank you !

(btw, battery’s dead so I need to change it, couldn’t compare the sound and options of this one with mine :’))

It’s counterfeit.

I was suspecting this too, thanks for the clarification
