to adjust - dig your thumbnail into the set mechanism to push it down. the crown is then moved to change the time.
there is no hack for the movement and the crown has one position as explained above.
when the nail set is not pushed in, the crown winds the watch as per normal.
the other types of setting are:
LEVER SET. Remove the bezel that holds the glass crystal. You will then see a small lever on either the right or left hand side of the dial. Pull this lever out. This engages the clutch and allows you to set the hands using the stem as if you were going to wind the watch. Turn the stem until the correct time appears on the watch. When the hands are set, push the lever back into place and replace the bezel.
KEY SET. Key set watches are some of the oldest types of watches made, dating well over one hundred years. If you have to wind your watch with a key, you probably need to use the same key to set the time. Here is what you do. Either remove the bezel or open the cover over the dial. You will see where the hands attach to the watch. Here you should notice a square shaped arbor. Place the key over this square and turn the hands until the correct time is shown. Remove the key, replace the bezel or cover and the job of setting the time on a key wind, key set watch is done.
PENDANT SET or STEM SET. Using the same stem and crown that you
wind your watch with, simply pull out on the crown until you notice a
click. This engages the clutch and now by turning the stem and crown,
you can set the correct time on your watch. When done, push the crown
back into place. - this is what we're all familar with today
