Feature: 5 Of The Most Complicated Models From A. Lange & Söhne

One of Germany’s most celebrated watchmakers, A. Lange & Söhne, has built up a reputation for creating stunning timepieces and movements that continue to push the boundaries within the watchmaking industry. With this in mind, let’s take a look at some of the most impressive and complicated watches in ALS’s catalogue.

Tourbograph Perpetual 'Pour le Merite' 706.025F

Building upon the first Tourbograph, introduced in 2005, is this spellbinding Tourbograph Perpetual 'Pour le Merite', released in 2017 at the Salon International de la Haute Horlogerie (SIHH) to great reception. This piece adds a perpetual calendar to the original mixture of split-seconds chronograph, tourbillon regulator, plus a chain and fusee constant force mechanism. This blend of complications makes it the most complicated watch within Lange’s offering … well, apart from the ridiculous Grand Complication, of course.

Richard Lange Jumping Seconds 252.032

Originally built for academics, researchers and explorers, A. Lange and Söhne’s Richard Lange—named after the late ALS co-owner—collection continues to boast strong precision and legibility. This reference was introduced in 2017 and boasts jumping seconds with a constant force mechanism, as well as hours and minutes. This model is a limited edition of just 100 pieces.

Triple Split 424.038F

ALS’s Triple Split is something of a game changer, being the world’s first and only split-seconds chronograph that can measure additive and comparative times for up to twelve hours. Pushing the parameters of mechanical watchmaking, the rattrapante minute and hour counters increase the measuring range by a factor of 24. This means the Triple Split can compare the times of two challengers in a sporting event, from a Formula One race to a marathon.

Lange 1 Tourbillon Perpetual Calendar 720.038F

This piece is rather unusual as it features a hidden tourbillon that is only visible via the open caseback. Other complications include: big size date, moonphase indicator, seconds sub dial, retrograde day-of-the-week and leap-year display at 6 o’clock and a peripheral rotating month ring, as well as a handy day/night display. In 2019, the retail price for this complication-packed timepiece was a whopping $335,800—a purchase not for the faint hearted.

Zeitwerk Decimal Strike 143.050

There are only 100 available of this limited-edition Zeitwerk and it is one visually arresting piece. In a stunning “honey gold” and “argenté” silver, this watch is likely to hit a chord with many for its charming chimes that strike every ten minutes and upon each hour. Not only that, but the Decimal Strike features jump hour and minutes, as well as small seconds and power reserve indicators.
