Press Release
Lange 1 Tourbillon Perpetual Calendar Handwerkskunst
Nomen est omen
A. Lange & Söhne is relaunching its horological opus magnum with the two eponymous complications – it had its debut just last year – in a special Handwerkskunst edition limited to 15 timepieces. It leverages the entire spectrum of artisanal skills mastered by the eminent Saxon manufactory.
The
Lange 1
Tourbillon Perpetual Calendar Handwerkskunst
combines two classic complications with the typical design of
A. Lange & Söhne’s most famous wristwatch: the Lange 1 .
Intelligently arranged around the time indications, the calendar
displays with the patented peripheral month ring deliver a host of
information at a single glance: date, day, month, leap year, and
moon phase. A decisive asset: all perpetual calendar displays advance
instantaneously. They are so harmoniously integrated in the dial
architecture that it takes a second look to grasp the technical
complexity of this horological masterpiece. To assure crisp
legibility, the refined tourbillon mechanism with the patented stop
function can be observed only on the caseback side.

The
dial is crafted from solid white gold and in this special edition is
decorated with a rare combination of tremblage and relief engraving
techniques. The manual work involved extends into the realm of the
smallest details: For the first time in a Lange timepiece, the blue
numerals of the outsize date display are hand-painted.

The
epithet Handwerkskunst
also applies to the decorations of the manufacture calibre L082.1
without reservation. They are the traditional counterpoints to the
avant-garde calibre design innovations. The relief-engraved
tourbillon and intermediate-wheel cocks frame the tourbillon ensemble
with the patented stop-seconds feature. The same free-hand engraving
technique is used to decorate the large central rotor in 21-carat
gold with a platinum centrifugal mass. Each of the three train
bridges is embellished with solarisation. The specular polish on the
upper side of the tourbillon cage is also a typical Lange quality
hallmark. Four screwed gold chatons and a diamond endstone bearing
for the tourbillion are the grand finale of Lange’s
“Handwerkskunst” extravaganza.

A 41.9-millimetre platinum case is the fitting highlight of this composition of precious metals. The A. Lange & Söhne signature and the case and edition serial numbers on the caseback are hand-engraved. This exclusive collectors’ item will be presented in September 2013 at the “Watches & Wonders” Haute Horlogerie Exhibition in Hong Kong. It comes in a limited edition of 15 watches that will be available exclusively through the eleven international A. Lange & Söhne Boutiques.
