Clock analog and actually two, main and backup. Mounted in a special "box" on the face the camera is aimed. The dial is black, he is constantly fades and his hand-tinted. And already then, in hardware paint it in blue, green or red.
Redundant clock used in the case if mostly arising any problem. Could one of the light bulbs burn out, there will be a spot on the dial, the arrow will fall off.
Watch these go without interruption since 1967. They go so far, but unfortunately, they have little time to go. Everything is changing, and soon they will be cut off.
