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.

SIHH 2010: A. Lange & Sohne Saxonia Annual CalendarA. Lange & Sohne went a long way developing the most complicated in-house movements and an addition to their extensive line of models of an Annual Calendar watch was only a matter of time. I am so glad it is a Saxonia model that successfully combines elegant appearance with intelligent design.A little bit of total disclosure here: when it comes to dressy watches, I am a sucker for Lange. Okay, now that I have said it I can more or less safely admit that my heart is bleeding when I read a torrent of press releases issued by the German manufacture.I mean, some of these models cost like a decent three-bedroom suburbian house and are still out of my reach especially now, when the global financial crisis finally starts showing its ugly face (Yeah, I think this is just the beginning of the real crisis and Greece is just one of the first real countries to call it quits on its enormous sovereign debt. God, I wish I was too pessimistic about this.) Let’s get down to business, though.The new A. Lange & Sohne Saxonia Annual Calendar comes powered by their recently developed L085.1 SAX-0-MAT automatic movement. Designed and built totally in-house, decorated and assembled by hand, this terrific example of German ingenuity sports Lange’s Zero-Reset function that makes the small second hand at 6 o’clock either fall back or spring forward to zero depending whether it is between 0 and 30 or 30 and 60 seconds position.Being an Annual Calendar, the watch is capable to show current date, day of week, month and even moon phase. It is not a perpetual calendar, so you will have to adjust the watch once a year, which is, let’s face it, still rather annoying. On the other hand, a perpetual calendar with leap year function would be a lot more expensive and more demanding to proper servicing, too.The movement seats inside a rather compact white (Ref. 330.026) or pink gold (Ref. 330.032) case 38.5 mm in diameter and only 9.8 mm in height, which is really wonderful for an automatic watch.
