If you have a crystal/bezel press, I would first seat the retention ring completely against the case.
Next, install the flat washer and then the click, which is the little metal wire. Following these parts, I would then install the bezel without the bezel insert; this will allow you to give the assembly a visual check to make sure all parts are engaging correctly. Once confirmed, remove the bezel, re-install the insert and snap the bezel back onto the assembly.
