Vita of Ferdinand Adolph Lange

18.02.1815: Ferdinand Adolph Lange is born in Dresden as the son of a gunsmith

1829–1831: Attends the technical college in Dresden

1830-1835: Watchmaking apprenticeship with Johann Christian Friedrich Gutkaes, graduates with honours

1835–1837: Assistant to Gutkaes

1837–1841: Journeyman years; travels to the watchmaking centres in France, England and Switzerland;  this is when he compiles his journey- and workbook with drawings of interesting movements and different calculations; becomes foreman at the manufactory of Joseph Thaddäus Winnerl in Paris; attends lectures of the famous physicist and astronomer Arago

1841–1842: Returns to Dresden; joins Gutkaes’ company as a co-proprietor and helps build the five-minute clock for the  Semper opera house; designs and crafts astronomical  pendulum clocks, chronometers, complicated watches

1842: Certifies as master craftsman; weds Antonia Gutkaes, his mentor’s daughter

1843: Receives a precious stick pin from the Russian Tsar Alexander II, as a gesture of gratitude for a perfect chronometer that Lange had crafted for him; in return Lange sends a photograph of himself wearing the stick pin

1844-1845: Different letters to Privy Councillor von Weißenbach containing thoughts on reforms in watchmaking and the establishment of a manufactory in Saxony

31.05.1845: Contract between Lange and the Royal Saxon Ministry of  the Interior: Obligates to train 15 apprentices as watchmakers, Ministry pledges a subsidy of 6,700 thalers, including  1,120 thalers for the procurement of tools

07.12.1845: Incorporation of “A. Lange & Comp.” company in  Glashütte, dials are labelled “A. Lange & Cie.”

1845–1864: Introduction of metric system to replace the Parisian ligne system; Lange develops proprietary dependable and robust movements

1848–1866: Serves as mayor in Glashütte (builds roads, embankments, bridges, etc.)

1851: Watch presentation at an exhibition in London, where he is awarded for his watches; an illness forces him to stay there for a few weeks

1867: Granted honorary citizenship by Glashütte

1868: Lange’s son Richard joins the company as co-proprietor; Company name changes to “A. Lange & Söhne”

1869–1875: Representative of the Saxon Landtag (lobbies for the construction of a main road and a railway line through the Müglitz valley)

1870: On the occasion of the 25thanniversary of the establishment of the watchmaking industry in Glashütte. The population establishes the Lange Foundation to fund retirement benefits for local watchmakers

1871: Ferdinand Adolph Lange’s son Emil joins the company as co-proprietor

When Ferdinand Adolph Lange suddenly passed away on 3 December 1875, he left behind not only a flourishing business and an impressive repertoire of international awards to his sons and grandchildren but also – to the Glashütte region – secure economic perspectives. For these accomplishments, the city honoured him with a monument in 1895. Ferdinand Adolph Lange repatriated precision watchmaking to Germany, enhanced with sweeping reforms. His designs, with wheel train parts exactly calculated for the first time, a new frame configuration with three quarter plates, the special Glashütte lever escapement and compensation balance, precision adjustment devices and hairsprings with special terminal curves represented the highest standards in watchmaking.

At auctions today, precision timepieces signed “A.Lange & Söhne”, among them highly complicated watches, fetch exceptionally high prices. For connoisseurs of mechanical timekeeping, they preserve the philosophy of a man who wrote many chapters of horological history and significant parts of Saxony’s history. The new watches from Glashütte signed “A. Lange & Söhne” carry this proud legacy forward into the future.

Ferdinand Adolph Lange is regarded as a pioneer in watchmaking. The Dresden born watchmaker introduced the metric system in horology. He invented measuring instruments, devised new tools and different constructions for which he applied a patent. With all that he was following just one aim: To build the best watches in the world. His innovative concepts created the foundation on which the A. Lange & Söhne brand gained international fame.

In summer 1851 Ferdinand Adolph Lange introduced his watches made in Glashütte in London at the World Exhibition, hoping to delight an international audience. It was the first time that he exhibited his watches at such an event and became a huge success: His watches were cheaper and more precise than the ones of his competitors. He even received a first prize and a medal for them. But then he has to pay a heavy price for his long lasting efforts: he becomes seriously ill and has to stay in London for a few weeks. It is probably for the first time in six years that he has the opportunity to consider his situation calmly and without distraction. He realises that he has dedicated himself in the past years and not just risked his company but also the existence of his family.

In a letter to the Saxon Ministry of the Interior he reflects about his accomplishments so far: “My first and decisive step was to design a gauge for executing with the greatest accuracy any calculated ratio in the smallest of scales. This was followed by my work on the ratios of pinions and pieces as well as the respective machines, and I finally established the principles to be observed when building watches and designing escapements in accordance with scientific fundamentals, and introduced methodologies and reliable processes where previously arbitrariness, prejudice and disaccord had reigned. These are the fruits of twenty years of painstaking deliberation and labour, parts of which have found practical application in our factory and make our watches good, but many others, whose time has come, remain unexecuted.”

Ferdinand Adolph Lange’s Most Important Innovations

The introduction of the metric system: In Lange’s journey- and workbook, he used to record detailed calculations for each individual gear-wheel size, using French lignes as units. On returning from his travels, he started to use the metric system instead of the French ligne units that had previously been the norm.

Precise measuring instruments : Tools like this dixième gauge invented by Lange made it possible to determine depth, length and external diameter with even more precision – to an accuracy of a tenth of a millimetre. The measuring results are shown on an arc-shaped scale by a metal arm.

Dial micrometer : This dial gauge was used to measure filigreed components that required particular precision, such as arbors and pivots. The component to be measured is clamped between the two jaws of the dial micrometer, which then measures with an accuracy of one hundredth of a millimetre.

Lathe : Lange introduced the watchmaker’s lathe to replace the traditional rotating arc. A pedal could be used to turn circular parts such as pins, pinions, wheels and discs at a constant speed – ensuring high-precision manufacturing.

The design of wheels and pinions: To reduce friction and thereby minimise abrasion, Lange calculated and designed the form of the teeth on gear-wheels and pinions to optimise their interaction.

Three-quarter plate: Lange developed the three-quarter plate over a period of many years. It improved the stability of the movement. This distinctive component became one of the characteristic features of his pocket watches. Today it still forms a major component of the watches made by A. Lange & Söhne.

Decorating the watch: By implementing high quality standards for any watch he made, Lange was following the motto of his teacher, Gutkaes: a watch must be perfect – from each individual component to the case. Fine engraving, guilloché work, finishing and polishing of his pocket watches still bear witness to this today.

Glashütter lever escapement: Lange aimed to make his watches more precise also led to the construction of an escapement system, the so called „free lever escapement“. Each pallet was made from one piece and the contoured pallet-stones were set blanketed.

Crown winding: This innovative technology replaced winding by means of a key, making it much easier to wind up the watch. An example is this early pocket watch (No. 1340), which Lange and his brother-in-law, Bernhard Gutkaes, produced in around 1850.

The jumping second : The “seconde morte” mechanism makes the seconds hand easier to read. Lange developed a mechanism, that makes an independent big seconds hand jump every second from the middle. His sons further developed this idea and a patent application was filed in 1877.

9-metre pendulum: In the new build manufactory of 1873 Lange realised a house clock with a 9-metre pendulum that oscillated uniformly. He personally designed the lever escapement of the movement and relied on his son Richard for calculating the pendulum.

Αφού συζητάμε για την ιστορία της Lange πρέπει οπωσδήποτε να γίνει και αναφορά στον Günter Blümlein.

Αφού συζητάμε για την ιστορία της Lange πρέπει οπωσδήποτε να γίνει και αναφορά στον Günter Blümlein.

With the restoration of several Swiss watch brands as well as the establishment of A. Lange & Söhne, he made major contributions to the renaissance of the mechanical watch after the quartz crisis in the 1970s.



His early death meant the loss of the visionary co-founder of A. Lange & Söhne and the demise of a charismatic entrepreneur and strategist for the world. His vision and enthusiasm outlast his passing away. What remains is his quest for outmost precision, his interpretation of form and quality, his perception of the bigger picture and his awareness of subtle differences. They are still embedded in every watch that leaves our manufactory.


“Without Günter Blümlein, A. Lange & Söhne would no longer exist – and Glashütte would not again be the centre of German precision watchmaking today.”



- Walter Lange, founder of Lange Uhren GmbH


Έχει δίκιο ο Βασίλης παιδιά, και ντρέπομαι να πω δεν τον ήξερα.

One of Günter Blümlein’s greatest achievements was the revival of the A. Lange & Söhne brand, essentially from scratch. Together with Walter Lange, he developed an integrated corporate, product and marketing concept that propelled the name A. Lange & Söhne back to the pinnacle of precision watchmaking where the brand stood prior to its involuntary hiatus of 40 years. No watch underscores this ambitious venture better than the TOURBILLON “Pour le Mérite”. Among the four watches of the first collection, it dominates the domain of horological complications. Its most precious feature is the fusée-and-chain transmission, a refined mechanism that equalises the waning force of the mainspring and that had never before been integrated in a wristwatch.



The innovative designs and mechanical inventions created under his guidance still reverberate today. Key developments at A. Lange & Söhne included the LANGE 1 with its new off-centre dial architecture and the first outsize date in a regularly produced wristwatch, as well as the first chronograph calibre crafted in-house for the DATOGRAPH.
