Step-by-Step Guide to Opening Different Illinois Pocket Watch Cases

Opening a Hinged Case

Gently locate the small lip or notch where the back cover hinges. Insert the case knife or your fingernail under this lip and carefully lift the back cover open. Avoid using excessive force to prevent bending the hinge or scratching the case.

Opening a Screw-Back Case

Place the rubber or friction ball firmly against the back cover. Turn counterclockwise with steady pressure to unscrew the back. If the cover is stuck, apply a small amount of penetrating oil around the edge, wait a few minutes, and try again. Never use metal tools to pry, as this may damage the threads.

Opening a Snap-Back Case

Identify the small notch along the edge of the back cover. Insert the case knife into this notch and carefully pry upward. Work slowly around the edge if necessary, lifting the cover evenly to avoid warping.
