Harry Potter’s Madam Pomfry’s brooch

[woozelmom]

Does anyone have a better picture of Madam Pomfrey’s Timer Brooch. I would imagine if she has to time a pulse or such she would pull one of the drop beads and the timer would rotate to let the sand fall.
Has anyone made one. Would love to see what you have done

I’m also interested to see if anyone has info on this brooch!
