You just take the bezel insert out then you can see a gap round the inner edge of the bezel, use a thin screwdriver and pull out the wire inside and then the bezel just comes off, The crystal on the silix case is glued in and can take a fair amount of force to get out and will probably break. Glue needs to be removed , soak in acetone and carefully scrape it out To put the bezel back on just sir it on the case and push the retaining wire back in Sent from my SM-G928F using Tapatalk
