When the Lange 1 Moon Phase was relaunched in late 2016, it debuted a new movement and a new way of depicting its namesake complication that incorporated a day/night indicator. I’ve always thought this was one of the cleverest moon phase displays out there. The moon is above us in the sky, of course, even when the sun is out, though the former is often outshone by the latter’s brightness. Lange’s moon phase display shows the moon’s position whether day or night, while distinguishing between the night sky and the daytime sky. This is thanks to two superimposed disks – one carries the Moon, and rotates twice per lunar month; the other, behind it, rotates once every twenty for hours, to show either a bright blue day sky, or an indigo evening sky with laser-cut stars. All of this happens within a display that also serves as the Lange 1 Moon Phase’s small-seconds subdial. The characteristics off-center design of the Lange 1, which is at once asymmetric and a picture of horological harmony, is still there, of course. In addition to the moon phase indicator and the display for the time, there are a large date display and a power-reserve indicator.
