    O-Rings

    O-rings are used to seal the backs of watches which feature either a press-in back or a screw-in-back. They ensure water resistance. O-rings may also be used on the winding stems of watches and in the winding crowns to protect against the water and dust penetration. The o-ring is normally made from a rubber or plastic compound.
