The positioning of the keyless-works parts for winding is shown in the green numbering. (1) The crown is pushed in, (2) the setting lever swings in, (3) the opposite end of the setting lever swings out allowing (4) the return lever to (5) slide the clutch into engagement with the winding pinion.
The red arrows show the power flow from (1) the stem, to (2) and (3) the clutch, to (4) the winding pinion, and then on to the crown gear and mainspring barrel (blue arrow).
