for setting stem with a screwdriver, etc. from
above.
(3) With the lever pressed, pull out the setting
stem.
2. When removing the setting stem from the movement
• Pressing the base of the unlocking lever for setting stem (“PUSH →” position), pull out the set-
ting stem.
<Note>
When the movement has been removed from the case, do not press the end of the unlocking
lever for setting stem. If it is pressed in this case, it may be pressed too much to deform

pulled out even if the unlocking lever for setting stem is pressed.
