Macro lenses have a very shallow depth of field making it impossible to get every part of a watch movement in focus when doing very close photography. With Photoshop you can take several images, each one gradually focused until the entire range of the subject has been covered, then blend them together automatically to one composite image where everything's in focus! It's pretty cool!
Here is a single image taken normally. Notice that only the balance rim and screws are in clear focus.
