Lange 1 Perpetual Calendar

The new LANGE 1 PERPETUAL CALENDAR is totally focused on the eponymous complication. Its integration into the prominent dial layout of the LANGE 1 was made possible thanks to a peripheral month ring created especially for this design

The new timepiece comes in pink gold with a grey-silver dial or – in a limited edition of 150 watches – in white gold with a solid pink-gold dial. The moon-phase display with an integrated day/night indicator is a further special feature.

Exactly 20 years ago, A. Lange & Söhne presented the LANGEMATIK PERPETUAL, its first wristwatch with a perpetual calendar. It was followed by seven further models, mostly in combination with other complications such as a chronograph, a tourbillon or both.

The perpetual calendar reconceived

Apart from the classic principle with calendar displays controlled by a 48-step cam, the LANGE 1 TOURBILLON PERPETUAL CALENDAR introduced in 2012 already took a different approach that has now been adopted by the new model. To integrate the calendar ensemble into the exceptional off-centre dial architecture of the LANGE 1 without compromising the harmonious balance of the displays, the month indication was implemented with a ring at the periphery of the dial that advances once a month. This patented design replaces the classic control principle with a 48-step cam. The innovation challenged the ingenuity of Lange’s engineers because advancing the ring at the end of the month requires considerably more power than traditional solutions.

A ring-shaped month display is complemented with the Lange outsize date, a retrograde day- of-week display, and a leap-year indication. The instantaneously advancing calendar displays are always crisply legible. They can be advanced collectively or individually with correctors. Once properly set, the mechanism is programmed to reliably indicate each month change until the year 2100.

Moon phase with day/night indicator

This perpetual calendar is the central complication of the LANGE 1 PERPETUAL CALENDAR, but not the only one. The watch additionally features a moon-phase display with an integrated day/night indicator.

The combination of the moon-phase display with a day/night indicator has two layers. It consists of a solid-gold celestial disc with a blue gradation. It completes one full revolution about its own axis every 24 hours. Against this background, the moon – either in white or pink gold – performs its synodic orbit in 29 days, 12 hours, 44 minutes, and three seconds with such precision that it takes 122.6 years before a correction by one day is needed. With the 2016 debut of the combined display in the LANGE 1 MOON PHASE, the moon appears on a monochrome light blue canopy during the day and on a dark blue starry sky at night.

Two exquisite colour variations

The LANGE 1 PERPETUAL CALENDAR has a diameter or 41.9 millimetres and a height of 12.1 millimetres. It is available in two versions. It comes in pink gold with a grey solid-silver dial and – in a 150-watch limited edition – in white gold with a solid pink-gold dial. The latter material combination has been presented by A. Lange & Söhne initially in 2019, in the DATOGRAPH PERPETUAL TOURBILLON, also a limited-edition model. Colour-coordinated hands and appliques in pink gold or rhodiumed gold – luminous in the pink-gold version – round off the harmonious design. The white-gold version has a dark-brown leather strap, the pink-gold model comes with a red-brown leather strap.
