This clock is considered as the most complicated Atmos clock. The movement was designed in 2003 in order to celebrate the Atmos' 75th anniversary by Jaeger-LeCoultre engineers in Le Sentier. In order to give an 'airy' and mesmerised feeling to the viewer they have decided  to conceal only the motor and the mainspring. The clock stands atop four cylindrical pillars made of Baccarat crystal. Because of frictional losses in the conveyance of energy, the motor in the base winds five conventional, serially switched, Atmos barrels. The transfer of energy to the clockwork occurs via a rotating glass staff, which is invisibly inserted into one of the pillars. This staff powers a glass disk situated behind the plane of the dial. The periphery of the disk bears a wreath of teeth made of gold plated brass. The glass disk completes one slow rotation around its own axis every 130 days.
This mechanism guarantees that energy is continuously and unvaryingly conveyed to the escapement-wheel and thus to the balance, regardless of how taut or slack the mainspring may be. Invented in the 19th century and primarily used in tower clocks, this device for regularity of winding consists of an intermediate energy reservoir in which a weight affixed to a longer lever sinks stepwise, thereby conveying energy to the escapement via the fourth wheel.

During this interval, the flow of energy coming from the barrel is interrupted. Every five minutes, however, all of the wheels leading from the barrel to the intermediate reservoir begin to turn, thereby raising the weight in the regularity-of winding mechanism.
