Abstract
A method for disassembling first and second watch-surfaces of a watch includes the steps of removing a decorative cover from the watch; rotating an adjusting screw to move an H-shaped snapping member toward a casing so that the H-shaped snapping member abuts against the adjusting screw; rotating a snapping ring so that an engaging protrusion does not overlap a pressing protrusion and the snapping ring can be removed from the casing; opening the watch; using a tool to press against a platform of the connecting sleeve; rotating the main screw to remove the connecting sleeve; removing the first watch-surface from the casing; removing first and second positioning rings and suspension columns; turning the casing to remove the snapping ring; opening the watch; using the tool to press against the platform; rotating the main screw to remove the connecting sleeve; and removing the second watch-surface from the casing.
