New Old Stock socketed Nixie tube (IN-18 Russian tube) display hours and minutes

½ a second with a slight pause between each digit to improve visibility.

of reading hour will captive the attention of every body and provide a non-stop
digit moving in the tube.
There is no external switch for
setting the clock; magnetic contacts (Reeds) are used in place. Setting the
clock is done with a small magnet (strong earth type).
It allows easy setting while
avoid people to change the setting when looking and touching the clock.
Placing the magnet at the front
top left angle of the box will set hours, top middle front angle for 10's minutes
and top front right angle for minutes. Also, the tube is red low lighted by
the bottom, when the magnet is correctly placed for setting, the bottom of the
tube is high lighted, this allow easy magnet positioning.
