** Illuminating a Watch Dial at Night [149]
This picture shows a watch holder, with a device to receive an
ordinary electric pocket lamp and battery. The battery is set in a
bracket under which a reflector extends downward to throw the
light on the dial of the watch and to protect the eyes from the
direct light. The entire stand and bracket are made from sheet
metal. The base is formed to make a tray to hold pins and collar
buttons. It is not necessary to seek in the darkness for a push
button or switch, as in ordinary devices, but a light pressure
with the palm of the hand will make the lamp glow.

object and the background.
