摘要

The movement has a display for displaying countdown by distinct mobiles, where the movement is arranged to drive the mobiles one after another, so that an additional mobile passes from one position to another position at each period of pre-defined duration during countdown. The number of mobiles in the former position indicates a number of remaining periods of the countdown. The mobiles are formed by cubes (52, 62, 72, 82, 92) provided with rotation axes (51, 61, 71, 81, 91). The cubes are associated with spiral springs (53, 63, 73, 83, 93) to return the cube toward the latter position.
