second hand starts to move, then pull the crown out to the second click.

position. Try not to stop the second hand movement for longer than 30
minutes. If it is necessary to remain holding the crown at the second
click position for longer than 30 minutes, push the crown back in once,
and wait for at least 30 seconds after the second hand restarts moving,
