Grand Lange 1 Moon Phase


The moon-phase display of the LANGE 1 MOON PHASE faithfully reproduces the progression of the earth’s companion in two respects: The lunar disc moves continuously, in contrast to comparable watches. And its mechanism calculated to such a degree of accuracy that it will deviate from the true position of the movement by only one day after having run without interruption for 122.6 years.

 Off-centre main dial. Subsidiary seconds with stop seconds. Moon-phase display. Outsize date display. UP/DOWN power-reserve indicator, 72 hours power reserve. Diameter is 38.5 mm and the height are 10.4 mm.
