LANGE 1 MOON PHASE
The next step in the Lange 1 evolution comes with a moonphase indicator that also pinpoints night or day. With the moon on a separate plane, as day turns to night, the disc behind it rotates, changing from clear blue skies to a darker one with stars. It’s a functional addition to ensure that you get the right time so the date doesn’t suddenly jump in the middle of the day. As a testament to Lange’s engineering prowess, the watch tracks the lunar cycle that takes 29 days, 12 hours, 44 minutes and three seconds—meaning it will only deviate from the true synodic period by one day every 122.6 years.
