The Lange 1 Moon Phase by A. Lange & Söhne is around since 2002. The Lange 1 received an upgrade quite recently and now it’s the turn of the Lange 1 Moon Phase. The watch now comes with a new calibre and the moon phase has also changed: it now contains a day/night indicator as well.
The arrangement of the moon phase display is based on a new, particularly realistic concept. A separate solid-gold moon pursues its orbit in the foreground. Behind it, a celestial dis – also made of solid gold – performs one revolution every 24 hours. On the disc, the different times of day are represented by varying blue hues caused by interference effects. During the day, it shows a bright sky without stars, while at night it depicts a dark sky with prominently contrasting laser-cut stars.
The lunar cycle endures 29 days, 12 hours, 44 minutes and 3 seconds on average. The Lange 1 Moon Phase displays it so accurately that it takes 122.6 years for the display to deviate from the true synodic period by just one day.
The asymmetric solid-silver dial sets a harmonious stage for the luminous time and power-reserve indications complemented with an outsize date, the moon-phase display, and the day/night indicator. Hours and minutes are displayed on a big subdial at 9 o’clock, the power-reserve indicator lies below the date at 3 o’clock. And A. Lange & Söhne incorporated the small seconds in the moon-phase display.
The now 20th (!) Lange calibre with a moon-phase display is based on the Lange 1 movement introduced two years ago, and it has the same performance attributes. This includes the maximum power reserve of 72 hours and the precisely jumping outsize date display. It beats with a frequency of 21,600 semi-oscillations per hour.
The 70 parts for the moon-phase display were so integrated in the L121.3 manufacture calibre that it is only marginally larger than the calibre L121.1 inside the Lange 1.
The Lange 1 Moon Phase is available in white gold with a black dial (39.500€), in pink gold with an argenté dial (35.900€) and in platinum with a rhodié dial (52.000€).
