On the dial side, Lange proves that it’s possible to create a watch that displays a lot of information in a coherent, minutely precise, and intuitive way – it’s cleaner even than the Datograph Perpetual. All the indications of the perpetual calendar, including the day, oversized “darth” date windows, moon, and leap year are displayed clearly. The perpetual calendar will, like all perpetual calendars, not require readjustment until the year 2100, and if the watch hasn’t run for a few days you can advance all indications simultaneously using a single pusher at 10 o’clock. Meanwhile, rhodium-plated, solid-gold hands remind us of the main objective of the watch – that of telling the time.
