The cannon pinion is broken. This is an uncommon part in this instance. I've been searching for one in my inventory all afternoon. No luck so far.

This click's shape, on that end, isn't critical at all to the movement's functioning. But without that little tail there's nothing to push on to let down the mainspring from the outside, for maintenance. The plate has a little hole in that spot so the ratchet can be released.

The mainspring was an almost new alloy spring with loads of strength, more than enough to drive the train right through the extra friction.
A truly clean, freshly lubricated movement needs very little power to run fine. In fact, a theoretical movement with zero friction would only need enough power to overcome the stationary mass of the gears and move them. But a stronger spring can push the mechanism through all sorts of problems, and grind away at bearings as it does so.
