What's inside of this Cadencia Palmer pocket metronome?

For as many of these little metronomes as you see online, there seems to be a dearth of information about how they actually operate. I decided to do a brief go over of the movement just so people had a little bit of an idea on how they work.

Is the bezel removed just by prying up?
