Welcome!
Is it me or does it appear that the screw head has sheared off and the screw body is still inside the bezel?
Usually a Easy-out does the trick to remove screws, but I can not say I have ever seen one small enough to a sscrew this size. I know there is a watch markers tool that is used to remove broken screws from movement bridges, but don't know if that will help here.
You might want to try a fine tip carbid dremel bit and score a slot in it, that way you can use a screwdriver to extract it. Regardless, best of luck!
