A. Lange & Söhne 165 Years – Homage to F. A. Lange Anniversary Collection

A. Lange & Söhne commemorates the spiritual legacy of the founder of Germany’s precision watchmaking industry by launching a a special collection of exceptional complications.

Presented in a novel gold alloy of hitherto unmatched hardness, the Homage to F. A. Lange Anniversary collection includes the TOURBOGRAPH “Pour le Mérite”, the LANGE 1 TOURBILLON, and the 1815 MOONPHASE .

It was in 1845 Ferdinand Adolph Lange moved to Glashütte to set up an ideal watch manufactory for crafting the world’s finest timepieces. Known for numerous inventions and enhancements in precision watchmaking, he was among the first members of his guild to adopt metric units of measurement and abandon the then prevalent but complicated Parisian ligne system.

His work was characterised by the quest for supreme precision. The drafts for mechanisms of his own design, even the most complicated ones, were exemplary as regards clarity of engineering and layout. His values remain the benchmark that inspires the work of all Lange employees.

The “165 Years – Homage to F.A. Lange” anniversary collection pays tribute to the founder of Germany’s precision watchmaking industry and to the trailblazing creations devised in his manufactory.

The capabilities of the manufactory are expressed by all three models with a novel case metal developed exclusively for Lange. With a Vickers hardness of over 300, the 18-carat honey-coloured gold exclusively developed for Lange is about twice as hard as other gold alloys.

Breathing beneath the hand-engraved balance cock made of the same material is a balance spring developed and manufactured in-house. It symbolises the innovative energy with which every Lange watch is endowed.

A guilloched solid gold dial and a sunburst finish on the three-quarter plate of the 1815 MOONPHASE and the crown wheel cock of the LANGE 1 TOURBILLON allude to the proud ancestral artisanship of the family tradition.

A. Lange & Söhne TOURBOGRAPH “Pour le Mérite” Honey Gold

In 2005, A. Lange & Söhne presented a grand complication that established a new benchmark in precision watchmaking: the TOURBOGRAPH “Pour le Mérite”. It was the first one-minute tourbillon in a wristwatch format with a fusée and- chain transmission as well as an additional rattrapante chronograph.

Because of the complexity of the mechanism, it was possible to craft only one watch per month. The coming of a second partial edition of 50 watches in a yet-to-be-defined gold version was announced on the occasion of the original debut. The TOURBOGRAPH “Pour le Mérite” which is now being presented in honour of Ferdinand Adolph Lange also has a case made of the new, harder gold.

A. Lange & Söhne LANGE 1 TOURBILLON with Stop Seconds Honey Gold

At the turn of the millennium, A. Lange & Söhne presented the LANGE 1 TOURBILLON based on the legendary LANGE 1. At that time, it was not yet possible to achieve what Lange’s calibre engineers accomplished a few years later with the CABARET TOURBILLON to directly and instantaneously stop the balance inside the rotating tourbillon cage.

With this feat, they corrected an intrinsic flaw of the tourbillon mechanism that for two hundred years was considered to be the ne plus ultra of horological sophistication.

While the elaborate device elevated the rate accuracy of a watch by overcoming the effects of gravity, it could not be stopped, so the watch could not be set to the second. Lange’s ingenious solution to the problem – the patented stop-seconds mechanism – is now integrated in the LANGE 1 TOURBILLON of the anniversary collection as well.

A mirror-polished bar made of honey coloured gold is precisely embedded in the dial and carries the tourbillon cage on the dial side.

A further special feature of this watch is the fact that the one-minute tourbillon is suspended between diamond endstones on both sides. A hallmark that Ferdinand Adolph Lange once introduced to sign the 1A quality category of his pocket watches.

A. Lange & Söhne 1815 MOONPHASE Honey Gold

The 1815 MOONPHASE epitomises Lange’s unending quest for the ultimate in precision. No effort was spared to calculate an extremely accurate moon-phase train for this watch.

A. Lange & Söhne 1815 MOONPHASE Honey Gold

Thanks to a suite of wheels with special transmission ratios, its error per lunar month is a nearly infinitesimal 6.61 seconds. It takes 1,058 years for this error to add up to a deviation of one day relative to the actual lunar cycle. The A. Lange & Söhne 1815 MOONPHASE Honey Gold watch features a 37.4mm diameter case and the manual-wound L943.2 movement.
