And here is the full assembly, with the setting lever spring back in place and the hour wheel in place:
Tres simple, n'est- ce pas?
I should mention the reason they do this is to provide some tension to the assembly. Have you ever noticed sometimes setting your watch, you wait for the time signal or the top of the minute (with a hacking movt usually) and then push the crown in to start the watch, and the hand sometimes slips back or forward a tiny bit? In most watches, the wheels in question are freewheeling and loose, so you get quite a bit of slop here, from the sliding pinion, through the intermediate wheels to the minute wheel itself.
