Check whether the watch back is a snap-on, screw-down, or held by screws
Place the watch face down on a soft cloth
Use the correct tool for the back type
For a snap-on back, insert a case knife or thin pry tool into the small notch
Gently twist or lift until the back pops off
For a screw-down back, use a case back opener or rubber ball and turn counterclockwise
For a back held by screws, use a small precision screwdriver to remove each screw
Keep pressure steady and avoid slipping
Store the back and screws safely after removal
If the back does not open easily, stop and use the proper tool or seek a professional
