Units should be immediately rinsed with fresh water before crystals can form.. Once formed they do not dissolve that easily.. especially since there is VERY little watter exchange (without removing bezels)..
Besides putting silicone in the holes (as was advised in earlier posts), how about soaking in some Salt-X (or equivalent) when doing the post-dive clean up after returning to port, and then rinsing? It is pretty tough to get a good rinse on the dive boat, which means it could be a while before returning to port and getting a chance to do a good post-dive rinse.
