I like that the open-heart Gentleman models show the escapement. After watching this video that a friend of a friend recommended me the other day, I’ve grown an appreciation for the Eta C07s. I wonder which one you have. Does it have the silicon balance spring?

Apparently it has either nylon or silicon instead of metal.
