Wrist watch recorder

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 need it becuase I've always got a lot of idea and things to note so I want something where I can register them and that
I can bring everywhere: in the swimming pool, under the shower, while I am jogging ecc.

You never know when the right idea arrives!!

Anyone knows a  truly impermeable or water resistant model?
Any suggestion or link?
Thanks to anyone that can help me.
