A little more detailed stem pic on which areas to lube.
Parts to lube:
1. the shoulder (that rides in the main plate and supports the outer end of the stem.)
2. the set lever notch (which carries the set lever pin and switches the keyless works as the stem is pulled in and out)
3. the clutch square ( which slides back and forth inside the clutch and drives the clutch)
4. the pivot ( which rides in a hole in the mainplate and supports the inner end of the stem)
Note: that light film of grease should be placed on each of the four flats of the clutch square.
*any innuendo regarding the title of this thread relating to anything else but watch parts is purely coincidental* Be Safe.
