As usual Bartosz with another extremely high quality post, I have one question, in this bit:

> However, when the driving gear can’t rotate because it’s blocked by the rest of the gear train, the cannon pinion can overpower the friction of that tight fit and rotate on its own. This lets us set time without interfering with the gear train, which could break the delicate parts.

How can the cannon pinion (green) both overpower the friction to slide freely and also be attached to the driving gear (blue) when functioning regularly?

Does this imply that the driving gear and cannon pinion wear each other out every time you adjust the time?
