SIHH 2016: A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar in white gold

A. Lange & Söhne LANGE 1 TOURBILLON PERPETUAL CALENDAR in white gold

Thanks to a clear arrangement of the calendar display around the time indication, the LANGE 1 TOURBILLON PERPETUAL CALENDAR presents an abundance of information at a single glance. The latest model of this horological masterpiece is now presented in a discreet white-gold case with a grey dial.

The LANGE 1 TOURBILLON PERPETUAL CALENDAR in white gold

The LANGE 1 TOURBILLON PERPETUAL CALENDAR combines two classic complications with the iconic design of A. Lange & Söhne’s most famous watch family. The calendar consists of a Lange outsize date, retrograde day-of-the-week and leap-year displays and a peripheral month ring. Due to the clear separation of the time and date, all information can be taken in at even a cursory glance. All of the perpetual calendar displays advance instantaneously. The mechanism is designed in such a way that it must be advanced only by one day in the year 2100. And the moon-phase display, located inside the subsidiary seconds dial, will even run true for 122.6 years before it needs to be corrected by one day.

A subtle inscription beneath the twelve refers to the existence of the tourbillon. By looking through the sapphire-crystal caseback, it can be admired in all its technical complexity. The movement is equipped with Lange’s patented stop-seconds mechanism. It brings the balance inside the tourbillon cage to a standstill instantly, gently and safely when the crown is pulled. This allows the watch to be set with one-second accuracy. The upper part of the tourbillon cage is decorated with black polish, the most sophisticated and time-consuming type of artisanal surface finishing. The bearing of the tourbillon cage features a diamond endstone as a tribute to the historic 1A pocket watches by A. Lange & Söhne.

A solid central rotor with a 21-carat-gold segment in the middle and an additional platinum centrifugal mass on the periphery efficiently tension the mainspring of the self-winding calibre L082.1 movement so that the maximum power reserve of 50 hours is built up after just a short time on the wrist. Typical Lange quality hallmarks include the lavishly decorated movement with hand-engraved tourbillon and intermediate wheel cocks as well as screwed gold chatons.

About A. Lange & Söhne

Dresden watchmaker Ferdinand Adolph Lange laid the cornerstone of Saxony’s precision watchmaking industry when he established his manufactory in 1845. His precious pocket watches remain highly coveted among collectors all over the world. The company was expropriated after World War II, and the name A. Lange & Söhne nearly vanished. In 1990, Ferdinand Adolph Lange’s great-grandson Walter Lange had the courage to relaunch the brand. Today, Lange crafts only a few thousand wristwatches in gold or platinum per year. They are endowed exclusively with proprietary movements that are lavishly decorated and assembled by hand. With 54 manufacture calibres developed since 1994, A. Lange & Söhne has secured a top-tier position among the world’s finest watch brands. Brand icons, such as the LANGE 1 with the first outsize date in a regularly produced wristwatch and the ZEITWERK with its precisely jumping numerals display, rank among the company’s greatest successes. Sophisticated complications such as the RICHARD LANGE PERPETUAL CALENDAR “Terraluna”, the ZEITWERK MINUTE REPEATER and the DATOGRAPH PERPETUAL TOURBILLON reflect the manufactory’s determination to achieve ever new pinnacles in horological artistry.
