1815 CHRONOGRAPH in white gold
Since 2010, the 1815 CHRONOGRAPH has been a paragon of classic design combined with advanced technology. With its Arabic numerals and railway-track minute scale, the dial recalls the charisma of A. Lange & Söhne’s coveted pocket watches. Paying tribute to the 200th birthday of Ferdinand Adolph Lange, who transformed Saxony into a centre of precision watchmaking in the 19th century, the eminent manufactory now presents a special edition of the chronograph.
In addition to deep-blue printed dial elements, the argenté-coloured face in solid silver features a pulsometer scale at its periphery. It is used for heart-rate measurements. This is done by stopping the time while counting 30 heartbeats. Then, on the pulsometer scale, the chronograph sweep-seconds hand provides a direct reading of the number of beats per minute. The hands reflect the colour combination of the dial: hours and minutes are indicated with rhodiumed-gold hands. The chronograph sweep-seconds, minute counter and subsidiary seconds hands are made of blued steel.
The L951.5 chronograph calibre is controlled by a column wheel, equipped with a snail for the precisely jumping minute counter and features a convenient flyback function. It has a power reserve of 60 hours. A large balance wheel with eccentric poising weights driven by a freely oscillating hairspring crafted in-house assures excellent rate accuracy.

About A. Lange & Söhne
When Ferdinand Adolph Lange, a Dresden watchmaker, established his watch manufactory in 1845, he laid the cornerstone of Saxony’s precision watchmaking. His precious pocket watches remain highly coveted among collectors all over the world. The company was expropriated after World War II, and the name A. Lange & Söhne nearly fell into oblivion. In 1990, Ferdinand Adolph Lange’s great-grandson Walter Lange had the courage to relaunch the brand. Today, Lange crafts only a few thousand wristwatches in gold or platinum per year. They are endowed exclusively with proprietary movements that are lavishly decorated and assembled by hand. In a period of little more than 20 years, A. Lange & Söhne developed 51 manufacture calibres and secured a top-tier position among the world’s finest watch brands. Its greatest successes include innovative time-keeping instruments such as the LANGE 1 with the first outsize date in a series produced wristwatch as well as the ZEITWERK with its supremely legible, precisely jumping numerals. In the meantime, both models have become icons of a brand rich in tradition. alange-soehne.com m
