How to Make Your Own LCD Clock

Lay the wristwatch face down in front of you. Loosen and remove the screws holding the watch layers together using a precision screwdriver set. Place the back of the watch to the side.

Locate the LCD display. This is a rectangular-shaped object positioned directly over the printed circuit board and display piece. The LCD will be held in place with a conductive rubber band. Use a screwdriver to release the band and remove the display.

Place the LCD component face down in front of you so the shiny or reflective side is facing up. Use a razor blade to peel away the reflective layer. Flip the LCD component over so you can see the display. Use the edge of the razor blade to lift off the filter on the top of the component. Flip the filter over and secure it back to the LCD.

Replace the LCD component back in the housing. Cut one piece of wire for each contact on the printed circuit board. The wire should be long enough to make contact with the LCD component when placed directly above the top of the housing. All of the wires should be the same length.

Heat the solder gun and solder one end of a piece of wire to each contact. Allow the solders to cool.

Replace the conductive rubber band, makings sure the band is positioned so all of the free ends of the wires are in good contact with the LCD component.

Place a magnifying glass in front of the LCD display. Place a high-intensity LED light behind the LCD display. The light will shine through the display, be magnified by the glass and project onto the wall.
