THE KEYLESS WORKS
Winding




CLICK ON A PART OR LABEL FOR MORE DETAIL












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).

During hand setting, all parts move in the direction opposite the green arrows. This brings the clutch into contact with the intermediate wheel, which drives the
minute wheel,
cannon pinion, and
hour wheel.
