  [*]is there a way to use him like a depth gauge ,becouse i am confused how to use him in the water ,thanks

Altimeters won't work as depth gauge, unless the watch is made and calibrated for it. In some cases the altitude could be perhaps re-calculated into depth manually, but I'd tell than mostly the watch will simply show an error when immerged, and not a value that could be used. Buy a watch with depth gauge, individual depth gauge, or a diving computer instead.

If you take that watch diving, you will permanently destroy the pressure sensor and it will no longer be able to read altitude.
