It's more convenience that you can appreciate the delicate mechanical movement. The interior of a watch movement including movement markings, numbers, shock absorbs, etc. can be seen at a glance with a transparent case back.
Therefore it is more easier to distinguish if it's a fake watch. And the timing (e.g. the amplitude of the balance wheel, the rotation of the rotor) can also be easily observed.
