Khashayar, you could try popping off the bezel with a knife, once you have access to the inside it is very easy remove all pearl glue with a pin and just slide down the pearl and reglue flush.....however be really careful using the knife method, easy slip and ruin hands (your hands ) or case, tape up everything and go slow and work your way around creating a gap between bezel and case, as it gets bigger the whole bezel should pop off. Usual method is to use something like an exacto knife to get a slight gap then move up to something thicker until bezel pops off.
