Timing device

Sokka used the timing device to keep track of the solar eclipse during the Invasion of the Fire Nation.

The timing device was developed by the mechanist for the invasion of the Fire Nation during the Day of Black Sun.[1]


The timing device was given to Sokka as a way to keep track of the amount of time before and during the eclipse, and was frequently used to observe the length of time passed.[2]


The timing device is a small, hexagonal handheld object similar in appearance to a timer. The mechanism is divided into six sections by six metal pins, with one of the sections having an open compartment consisting of a needle and a series of notches used to calculate elapsed time. The timing device is a mechanical apparatus that is initiated when the user winds it using a little key that is inserted in the square hole at the center of the device.[1]
