Right on time for the start of spring, A. Lange & Söhne presents a special edition of the Richard Lange in white gold and with blued steel hands. From April 2013, this new variation is available exclusively at the boutiques of the traditional Saxon watch brand.
In 2006, A. Lange & Söhne revived the grand tradition of scientific observation watches with the launch of the Richard Lange. They were once indispensable in navigation and as precision instruments for scientists. Reduced to the function of exact time measurement, the new boutique edition of the three-hand watch with sweep seconds comes in a white-gold case for the first time, with the familiar diameter of 40.5 millimetres. Hands in blued steel over an argenté-coloured solid-silver dial assure excellent high-contrast legibility of the time.
The Richard Lange pays tribute to Ferdinand A. Lange’s eldest son. During his entire life, the long-tenured technical director of the manufactory focused on evolving precision watchmaking on the basis of scientific research. The balance spring is a manifestation of what is no doubt his greatest achievement. In 1929, he recognised that the addition of beryllium to the nickel-steel alloy made hairsprings less susceptible to temperature fluctuations and simultaneously more elastic. Richard Lange’s insight, for which a patent was granted in the following year, resulted in a quantum leap in precision and expedited the development of a timepiece category that defines itself in terms of accuracy: the observation watch.
The Richard Lange was inspired by the characteristic traits of its historic predecessor and re-interprets them with contemporary panache. With its white-gold case and the exquisite finissage of the movement, it is a very accurate observation wristwatch that befits our era. This special edition of the Richard Lange is available exclusively through the A. Lange & Söhne boutiques. Only a few pieces can be handcrafted per year.
