Petite Lange 1 Phases de Lune
The Little Lange 1 Moon Phase comes with a guilloché
silver-coloured, is inscribed with two golden moons. This astronomical
complication reproduces the synodic orbit so accurately that after 122.6 years
it will differ from the actual position of the moon by just one day. The new,
years ago, includes a twin barrel to deliver a 72-hour power reserve, and a
hand-engraved, one of the hallmarks of an A. Lange & Söhne watch.
