THE ART OF WATCHMAKING

DISCOVER HOW LANGE TIMEPIECES ARE CRAFTED BY HAND

Our craft is characterised by tradition. It can be found in classical elements as well as sophisticated watchmaking complications. For example, all our balance cocks are engraved by hand. Each engraver has their own personal style, making each timepiece unique. Even parts that lie inside the movement are bevelled, polished and engraved. From the classic model with only two hands to large complications, each timepiece is finished to perfection. All this culminates in our HANDWERKSKUNST models. And there is another step in the manufacturing process that goes into every Lange watch – the twofold assembly. With an A. Lange & Söhne, you are not only acquiring an exceptional timepiece, but also several hours of elaborate craftsmanship.

Influenced by Walter Lange's motto “There is something that you demand not only of your watch, but also of yourself: never stand still”, nothing seems impossible for our watchmakers. This is apparent by the many patents and advanced designs that have revolutionised fine watchmaking. Like the TRIPLE SPLIT – the world's first mechanical rattrapante chronograph that allows comparative time measurements over several hours, accurate to the sixth of a second.

LANGE BALANCE SPRING
LANGE BALANCE SPRING
Crafting a balance spring is one of the most complicated tasks in precision watchmaking, one that only very few manufactories master.
THE ART OF ENAMELLING
THE ART OF ENAMELLING
Crafting an enamel dial is very complex, requires several days of work, and calls for the utmost in precision.

Lange models incorporate either annual calendars or perpetual calendars.
CHRONOGRAPH
CHRONOGRAPH
Chronographs and their manufacture movements have been flagship products of A. Lange & Söhne since 1999.
OUTSIZE DATE

OUTSIZE DATE

The A. Lange & Söhne outsize date enables a date display with digits around three times as large as those in watches of comparable dimensions.
CONSTANT-FORCE ESCAPEMENT
CONSTANT-FORCE ESCAPEMENT
The purpose of a constant-force escapement in a mechanical watch is to provide the escapement with a consistent flow of power, regardless of whether the watch is fully wound or nearly unwound.
CHIMING MECHANISM

Since 2011, our HANDWERKSKUNST models have been taking the finissage of cases, movements, and dials to a new level of excellence.
TOURBILLON WATCHES

TOURBILLON WATCHES

The tourbillon improves the rate accuracy of a mechanical timepiece by overcoming the influence of gravity on the running of a watch.
ZERO-RESET MECHANISM
ZERO-RESET MECHANISM
With the ZERO-RESET mechanism, the movement stops and the seconds hand jumps to zero when the crown is pulled.
FLYBACK MECHANISM
FLYBACK MECHANISM
The precisely jumping minute counter and the flyback function have been two features of Lange chronographs since 1999.
JUMPING SECONDS MECHANISM
JUMPING SECONDS MECHANISM
The mechanism of the jumping second assures unambiguous readings at any time, because it advances the large seconds hand by exactly 60 steps per minute.
