Where do you think I can buy an impermeable watch with voice recorder?

[Sabatino]

Hallo to all.
I am looking for a good impermeable or underwater clock with voice recorder function, even like that one of the cellular phone, where you click a button and it register, but I can't find it.
I bought something like that, the casio DBV 3000, but it wasn't impermeable .
I bought a chinese one too, it says "water resistant", but when you go under the water a few humidity passes and the contacts are oxidized therefore it doesn't works anymore.
Anyone knows a truly impermeable or water resistant model?
I use the clock inside the water but outside the register…
Any suggestion or link?
Thanks to anyone that can help me.

Why does it need to be a watch? You're trying to record your voice while diving? A full face mask with voice transmitter is your best and most expensive option. If you want to go ghetto you can put a little digital audio recorder in a dry box and take it under but you may not get any usable audio out of it. If I'm misunderstanding your intentions, please let us know.

I use the clock inside the water but outside to register my memo…
