The reason the altimeter is set the way it was in the old training film was to eliminate any slack in the linkage. You would go below the current setting by a small amount, then slowly come up to the current setting.
Another interesting piece of trivia is that each barometric altimeter also had a thumper built into the rear of the instrument called an altimeter vibrator. The idea was that the vibrator would prevent the indicator from sticking.
Here is a screen capture from the CS 757 overhead panel.
The 707 panel was too worn out to read.
