7. Arnold and Son True Moon
When keeping track of the moon is as important as keeping track of your schedule, look no further than the Arnold and Son True Moon. With a separate movement tracking the moon's 29 day month, the moon's phases are displayed through 18 revolving moon-shaped discs at the bottom of the face - we don't know how we lived without this.
