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.
