The Manufacture Jaeger-LeCoultre is helping you to achieve the correct setting of your moon-phase.
You will find a tutorial explaining how to set your moon-phase, a full moon calendar and moon-phases indicators of our different collections; Master, Reverso, Duomètre, Rendez-Vous and Atmos.
Correction of the moon-phase should not be performed between 10:00 p.m. and 3:00 a.m. During that period the automatic date change mechanism is already in action.
