A. Lange & Söhne presents the RICHARD LANGE “Pour le Mérite

A. Lange & Söhne presents the RICHARD LANGE “Pour le Mérite” in white Gold. With a limited 218-watch edition of the RICHARD LANGE “Pour le Mérite”, A. Lange & Söhne revives the concept of the uncompromisingly precise timekeeping instrument. The new version in white gold with a black dial had its debut at the company’s international dealer convention in Dresden on 22 September 2016.

Its fusée-and-chain transmission ensures constant torque and superb rate accuracy.
Since the inaugural collection of the new era was showcased in the autumn of 1994, the exclusive timepieces with the attribute “Pour le Mérite” have represented the technological avantgarde at A. Lange & Söhne. Each of the four models launched so far is endowed with a fusée-and-chain mechanism. The RICHARD LANGE “Pour le Mérite”, first introduced in 2009, exemplifies an ambitious tribute to precision in its purest form:
the sole objective of its complication, discernible only on the movement side, is to improve rate accuracy. The pink-gold and platinum versions, now sold out, are now being complemented with a limited white-gold edition featuring a black dial.

The solid white-gold case of the new edition has a diameter of 40.5 millimetres. White Roman numerals and the rhodiumed gold hands contrast well against the black silver dial. Small Arabic numerals in red for 15, 30, 45, and 60 minutes add handsome nuances of
colour to the underlying black-and-white design. A hand-stitched black alligator leather strap with solid white-gold buckle underscores the stylistic clarity of the RICHARD LANGE “Pour le Mérite”.

Utmost technical complexity

The salient technical hallmark of the RICHARD LANGE “Pour le Mérite” – and of all “Pour le Mérite” models since 1994 – is a fusée-and-chain transmission that consummately defined new benchmarks in precision watchmaking. Inspired by historic pocket watches and integrated into a wristwatch by A. Lange & Söhne for the first time, the mechanism guarantees constant torque and thus stability of the amplitude of the balance across the entire power-reserve range. Wrapped around the mainspring barrel, the chain delivers the power of the mainspring to the wheel train via the cone-shaped fusée. This keeps the torque constant. When the watch is fully wound, the chain pulls at the smaller circumference of the fusée, i.e. at the shorter lever. Conversely, when the tension of the mainspring is nearly depleted, the chain pulls at the larger circumference of the fusée, the longer lever. But the most important parts of the fusée-and-chain device are clearly visible through the sapphire-crystal caseback. Generously dimensioned openings in the three-quarter plate made of German silverreveal the mechanism.

Perfection down to the last detail
In the heart of the manufacture calibre L044.1, crafted to the strictest Lange quality criteria
and lavishly decorated by hand, a freely oscillating Lange hairspring powers the large
screw balance at a frequency of 21,600 semi-oscillations per hour. With four solid-gold
poising screws, its moment of inertia can be adjusted precisely to the torque delivered by
the fusée. The splendid finissage of all movement parts even includes straight graining of
the upper side of the chain, which is also crafted in-house. Manifesting artisanship at its
finest, the engravings on the balance cock as well as on the escape-wheel and fourthwheel
cock give each of the 218 watches the status of a unique work of art. The number of
watches of this edition has a special meaning. The current number of global points of sale
at which A. Lange & Söhne timepieces are available is 218.
