In many areas of luxury the end consumer is often met with the finished product with little idea of how that product was actually developed the way it was, nor why. Here A. Lange & Sohne provides a fascinating insight into how it approached three technical areas of watch*** and reveal how each of those paths evolved.The first of Lange's innovations for 2010 is harder gold (top). Chemically speaking, this novel "honey-coloured" gold is an 18-carat gold alloy which means it consists of 75 percent pure gold. Its colour lies midway between pink and white gold and is attribut-able to its copper and zinc content.The combination of a special thermal treatment with a slight admixture of man-ganese is responsible for its extraordi-nary hardness which registers between 300-320 HV on the Vickers scale. To put that in perspective, yellow gold's value lies between 135-150 HV meaning honey-coloured gold is more than twice as hard. The benefits to the watchmaker and the wearer are obvious, offering far improved scratch resistance and durability.Meanwhile another of Lange's discoveries for 2010 centres round its Zeitwerk timepiece (above) which boasts numerals that are obscured behind the dial for most of the day. To ensure the wearer can read the time in the dead of night, the numerals’ ability to absorb light had to be addressed.Lange's solution was to create a sapphire-crystal dial with a semi-transparent but UV-permeable coating. The light in the ultra-violet (UV) range from 250 to 430 nanometres is allowed to pass unhindered so the Superluminova numerals can be charged up with photonic energy even when obscured behind the dial. This allows them to glow for several hours at night despite not seeing sunlight in the traditional sense for much of the day.The final innovation likewise involves luminosity but is related to lunar discs rather than numerals. Lange's 1815 Moonphase is accurate to such a degree that it takes over a thousand years for the display to be off by one day relative to the moon's position. Maintaining this excellence, Lange wanted to develop a coating for the stars that would genuinely emulate the appearance of the night sky.The brand employed a group of scientists who pioneered a new process in the watch*** industry in which they apply extremely hard carbon films to the solid-gold lunar discs through physical vapour deposition �C known as PVD. This adjustment of the su***ce not only delivers the desired col-our hue but also very high wear resistance. The lunar discs are crisp and brilliant.

A. Lange & Sohne (A Lange & Sons) is a German prestigious watch-*** powerhouse, founded in 1845, in a small town in Saxony, by a young enthusiast watchmaker, Ferdinand Adolph Lange, who initiated a long heirloom of master watchmakers. After a very interesting historical evolution, the brand grew into one of the most appreciated members of the Haute Horology.Nowadays, A. Lange & Sohne belongs to the Richemont Group; and, for the watch-connoisseurs worldwide, the brand's name is synonymous with German finest watch-*** tradition, and elevated quality standards, the embodiment of uncompromising innovation, timeless beauty and mechanical perfection. A. Lange Sohne Datograph Perpetual in White Gold Picture GalleryRecently the brand created another exceptional variation of the remarkable A. Lange & Sohne Datograph Perpetual, a superb elegant timepiece that ingeniously combines a flyback chronograph, a white gold reinterpretation of the perpetual calendar complication smoothly incorporated into the architecture of the stylish grey dial. The sophisticated timepiece features an elegant, satin-polished 18-karat white gold case, measuring 41 mm in diameter, which incorporates two anti-glare coated sapphire crystals and a stylish crocodile leather strap secured to the wrist by an 18-karat, white gold prong buckle.Designed to please the brand's demanding clientele the remarkable A. Lange & Sohne Datograph Perpetual, maintains the u***takable DNA of a classical Lange chronograph watch- the column wheel mechanism, the flyback function, and the jumping minute chronograph counter. The skilled engineering team of the brand masterfully intertwined these function with the zest of the timepiece, a perpetual calendar complication that ensures the outsized date, moon phase, day, month, leap years functions and a day/night indicator. The accuracy of the perpetual calendar mechanism does not require adjustments until 2100, a secular year in the Georgian calendar, and the moon phase indicator has to be corrected once every 122 years.At the heart of this outstanding horological creation beats the in-house highly complicated hand-wound movement, the A. Lange & Sohne caliber L952.1 constructed from 556 individual parts, which reveal extremely delicate manual high-end finish that can be admired, by a true connoisseur's eye, through the exhibition case-back of the watch.Designed for a powerful, charismatic gentleman of the 21st century, keen on supreme beauty and technical excellence, the remarkable A. Lange & Sohne Datograph Perpetual, confers the advantage of 36-hours power reserve, and it will be available for a sky-high price tag of $120,190.00.A.
