There are numerous illustrated guides in the Watchmaking forum, but this is the basic procedure - Pull the stem out to the time-setting position Remove the caseback Remove the 2 bridles/tabs with screws along the perimeter that fix the movement in the case Press the stem release button near the stem (press only enough to release the stem - too hard & you may disengage the keyless works, so the stem will not lock back in) Place some lint-free paper in the palm of your hand (to keep from touching the movement with your skin), turn the case over & gently allow the movement to slide out Slide a small sheet of plastic or thin cardboard between the hour hand (or bottom hand on the stack) & the dial to protect the dial Assuming you do not have a hand-puller, take a pair of small flat-head jewelers screwdrivers (make sure the tips are both clean & in good shape) & insert them between the second hand & minute hand from opposite sides, 180 degrees apart from each other (east & west). Gently rotate each screwdrive in an opposite direction until the second hand slides off the stack & carefully remove it. Repeat for the minute & hour hands. Loosen the 2 screws on the side of the pillar (main) plate of the movement to release the dial feet & you can then either lift the dial off or gently slide a small, flat-head screwdriver between the bottom of the dial & top of pillar to lift the dial off.
Good luck.
