The mainspring can be re-oiled through the two holes in
the back frame as perviously described and should be done with
the mainspring approximately half wound.
To introduce oil between the slipping tail and the inside of
the barrel, it is necessary to hold the movement at about 45°, the
barrel and front frame uppermost, and using an oiler, wipe oil
into the space between the outside diameter of the barrel and the
barrel sweeping in the back frame. This oil will work up between
the slipping tail and the inside of the barrel.
On later models one of the oil holes in the back frame has
been moved specifically to facilitate oiling of the slipping tail.
On models where it has been done, this can be clearly seen.
MODEL 23 MOVEMENT
6-3/4 X 8 LIGNE
This new miniaturized version of the Model 22 movement
is available in both men's and ladies' models. Basically the dis
mantling, cleaning and repairing of a Model 23 watch is similar
to that already shown for the Model 22. There are some design
features of the Model 23, however, which slightly alter the pro
cedure. This is shown on the descriptive drawings attached.
Plate XIII) Completely exploded view of movement.
Plate XrV) Changing crown and stem.
The movement may be cleaned after removal of the cannon
pinion, balance wheel, ratchet wheel bridge, ratchet wheel and
click.
