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 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 end stone 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.
