Jaeger LeCoultre have released a limited edition of their Atmos clock to commemorate the eightieth anniversary of the first Atmos clock which used an almost identical movement. The Atmos Birthday Clock was created as the perfect gift for a newborn baby and is available with either a baby blue or baby pink dial which says Atmos Birthday on it. The clock uses the caliber 564 movement which is powered by small changes in temperature. The Jaeger LeCoultre Atmos Birthday Clock comes in a crystal case with a stainless steel pedestal which can be engraved with an inscription, only eight will be made.
