How do I replace the workings of a digital watch?

It is possible but you must be sure that the movements are compatible before you start. To remove the stem you will find a small hole or raised piece of metal on the body of the movement (depending on the make of movement) near to the stem. With a small instrument you need to gently push into the hole or on the raised piece, at the same time gently pull the stem away from the movement. Good luck
