Thanks to a clear arrangement of the calendar display around the time indication, the new A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar just released at the SIHH 2016 Salon International de la Haute Horlogerie presents an abundance of information at a single glance. The latest model of this horological masterpiece is now presented in a discreet 18K white gold case measuring 41.9 mm in diameter by 12.2 mm in thickness, all rounded out by a gorgeous solid silver grey dial.
The new SIHH 2016 A. Lange & Söhne 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 over sized date, retrograde day of the week, leap-year aperture at 6 o'clock and a peripheral month ring indicator. 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 Roman numeral refers to the existence of tourbillon. By looking looking through the sapphire-crystal case back it can be admired in all its technical complexity. The automatic in-house movement Lange calibre L082.1 is equipped with Lange’s patented stop-seconds mechanism. It brings the balance inside cage to a standstill instantly, gently and safely when the crown is pulled. This allows the watch to be set with one-second accuracy when the crown is pulled. The upper part of the tourbillon cage is decorated with black polish, most sophisticated and time-consuming type surface finishing. The bearing of the tourbillon cage features a diamond endstone as tribute to the historic 1A pocket watches by A. Lange & Söhne. Additionally, a solid central rotor with a 21K gold segment in the middle and an additional platinum centrifugal mass on the periphery efficiently tension the mainspring of the calibre 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 lavishly decorated movement with hand engraved tourbillon and intermediate wheel cocks, as well as 76 jewels —six screwed in gold chatons including one diamond endstone.
On the wrist, the watch wears true to its actual size and simply impeccably. The watch is supplied with a hand-sewn black alligator strap with matching Lange white gold deployant buckle. The new SIHH 2016 Lange 1 Tourbillon Perpetual Calendar is simply one of our favorite watches from this year's salon in Geneva.
