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 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.
