With one finger, you can represent a max of two different numbers (up and down). With two fingers, you can represent four numbers max (2x2). Eight numbers max with three fingers (2x2x2). Sixteen numbers max with four fingers (2x2x2x2). and finally, thirty-two unique numbers max with five (2x2x2x2x2)
To be more precise, it acts as a shock absorber between the reset hammer (like in a chronograph), and a second lever which disengages the vertical clutch that drives the seconds hand. Probably acts as a buffer/safety for slight tolerance issues, so that the vertical clutch doesn't get damaged in the

One of the photos show a rattrapante pocket watch, which does indeed, have the top subdial sitting slightly higher up than the lower one! (I verified it by measuring the photo digitally) I

Two clicks are fixed to the inner ring of the crown wheel, which both interact with a fixed star wheel/ratchet hub. The hub itself can freely rotate slightly, as it has two radial track/grooves. This allows for the "slack" to prevent overwind of the mainspring at its fully-wound limit, just like a r
