The crown opened is designed to keep the watch sealed and intact at surface pressures not at depth! Open a crown while diving at 100ft and see what happens.

I get 184 psi .
So if by opening the crown, he filled it up to pressure, he's definitely going to see if the HEV works. It relieves at 3 to 5 atmospheres differential pressure which it will see several times during decompression. At 184 psi it is at 12.5 atmospheres.
