A. Lange & Söhne 1815 Chronograph 414.028 – the chronograph where the movement is the main attraction

A. Lange & Söhne rarely needs to shout to make itself heard. The 1815 Chronograph reference 414.028 is perhaps the clearest example. On the front we are met by a black dial, white gold and an almost restrained classic design language. Turn the watch over and everything changes. There awaits one of the modern watch industry's most beautiful and most fascinating chronograph movements. We take a closer look at a model that sums up much of what has made A. Lange & Söhne one of the world's most respected manufacturers.

Background

There are watches whose significance is immediately visible. They have tourbillons, perpetual calendars, minute repeaters or constructions that require an instruction book just to understand what is happening on the dial.

The A. Lange & Söhne 1815 Chronograph is almost the opposite.

Here there are hours, minutes, small seconds and a chronograph. No date. No tourbillon. No moon phase. Not even automatic winding. On paper it is hard to describe the model as particularly complicated.

But that is also precisely where you risk missing the point.

To understand the 1815 Chronograph you have to go back to the resurrection of A. Lange & Söhne and above all to 1999. That was when the German manufacturer presented the Datograph – a watch that in many ways changed the view of the modern mechanical chronograph.

When A. Lange & Söhne was relaunched in 1994 the brand was still in the process of establishing its position among the world's foremost manufacturers. Five years later came one of the strongest arguments so far. The Datograph combined a large date display with an in-house developed, integrated, manual chronograph movement with a column wheel, flyback and a horizontal clutch.

It was not just technically impressive. The movement looked as if someone had built a mechanical city under sapphire crystal.

It would become one of Lange's strongest hallmarks.

From the Datograph to the 1815 Chronograph

In 2004 A. Lange & Söhne took the next step and presented the 1815 Chronograph. Fundamentally the model built on the same chronograph architecture that had made the Datograph famous, but without the large date display and without the power reserve indicator.

The result was something curious: a simpler watch that in certain respects let the chronograph itself come across even more clearly.

The 1815 Chronograph became thinner and more classically proportioned. The dial took its design language from older pocket watches from Glashütte with Arabic numerals, a railway minute track and two symmetrical registers. The name 1815 of course refers to Ferdinand Adolph Lange's year of birth and places the model clearly within the brand's historical tradition.

The first generation was manufactured from 2004 and had among other things a clear pulsometer scale around the periphery of the dial. When the model returned in updated form in 2010 the case had grown marginally to 39,5 millimetres and the new calibre L951.5 gave a full 60 hours of power reserve. The pulsometer scale disappeared at the same time and the registers grew. 

But the story did not end there.

In 2015 the pulsometer returned on a special boutique version. Two years later the watch that for many would become the definitive modern 1815 Chronograph was presented: reference 414.028. 

414.028 – black, white gold and almost perfect balance

It is easy to understand why the 414.028 has gained an almost cult-like standing among Lange enthusiasts.

The case is made in 18 carat white gold and measures 39,5 millimetres in diameter and only 11 millimetres in height. In an age where advanced chronographs have readily grown far beyond 40 millimetres, the proportions are almost remarkably restrained. 

The dial is made in solid silver but executed in deep black. Against it contrast white Arabic numerals, the classic railway minute track and rhodium-plated hands. At nine o'clock lies the small seconds and at three o'clock the chronograph's 30-minute counter.

Furthest out is found the pulsometer, graduated from 40 to 200 beats per minute. The function is a remnant from the time when doctors actually used the chronograph as a working tool: start the chronograph, count 30 heartbeats and then read the pulse directly off the scale.

In practice, extremely few owners of a 414.028 are likely to diagnose patients with their Lange. But the scale is important for another reason. It gives the dial one more layer and ties the modern watch together with the first generation 1815 Chronograph.

It is at the same time an unusually successful combination of old and new. Where earlier versions can sometimes be perceived as more outspokenly classic, the black dial and the white gold case create a considerably harder character.

Almost a German equivalent of the classic black Datograph – only scaled down to the absolutely necessary.

Turn the watch over

Even so the dial is only half the experience.

If you turn the 414.028 over, the manual calibre L951.5is revealed, and here it becomes clear why the 1815 Chronograph plays in a different league than the relatively simple list of functions suggests.

The movement consists of 306 parts and 34 jewels, works at 18 000 vibrations per hour, corresponding to 2,5 Hz, and offers around 60 hours of power reserve. 

But the numbers really tell very little.

The spectacular part lies in the construction.

Unlike many modern chronograph movements where the mechanism is largely hidden beneath bridges, Lange's chronograph is built upwards. Levers, springs, wheels and screws lie on top of each other and create a mechanical landscape with an almost three-dimensional depth.

Here you can see the column wheel that controls the chronograph's functions, the levers of the flyback mechanism and the construction that makes the minute counter jump exactly from one minute to the next. Lange themselves highlight precisely the possibility of seeing these mechanical processes through the sapphire crystal as a central part of the model. 

If you press the reset button while the chronograph is running, the hands immediately return to zero and then begin a new timing. Hence the name flyback.

It should therefore not be confused with a rattrapante or split-seconds chronograph, where two central chronograph hands can be separated in order to measure for example intermediate times. Lange masters that complication too – the Double Split from 2004 took the concept considerably further – but the 1815 Chronograph is about something else.

Pure chronograph mechanics.

Bridges and movement plates are made in untreated German silver. Blued screws meet screwed gold chatons. Edges are polished and bevelled. The column wheel has mirror-polished surfaces and the balance cock is hand-engraved.

A. Lange & Söhne is moreover known for its so-called double assembly. The movement is first assembled to make sure everything works, is then taken apart, the components are cleaned and the final finishing is done before the movement is assembled a second time.

It is a completely unreasonable way to build a watch.

Which is also part of the charm.

On an ordinary watch the sapphire crystal in the case back works as a way of showing the movement. On an 1815 Chronograph it feels almost the other way round: the rest of the watch is there to give a reason to carry the L951.5 around.

Stories of Time

Stories of Time is based in Stockholm and consists of a team of watch collectors and enthusiasts with long experience of international trade in exclusive wristwatches. The business works with both modern, hard-to-get models and older collector's items, and also offers help with purchase, sale and service.

The A. Lange & Söhne 1815 Chronograph 414.028 is a fitting object in such a context. It is not necessarily the Lange model that first comes up when the brand's modern history is discussed – there the Lange 1, the Datograph or one of the more advanced complications often end up at the centre. For the collector the 1815 Chronograph is instead interesting because it offers something more concentrated: a classic chronograph where almost all attention can be directed towards the construction, the proportions and the exceptional movement.

The execution in question is moreover one of the model's most characterful. The combination of white gold, a black dial and the pulsometer's fine scale gives the 414.028 a considerably sportier and more contemporary appearance than many other models from A. Lange & Söhne. At the same time it keeps the dimensions and the design language that make the 1815 series clearly anchored in the brand's history.

But the real main attraction is still on the back. The calibre L951.5 is one of those movements that remind us why A. Lange & Söhne, so shortly after the relaunch, was able to establish itself among the very foremost names of modern haute horlogerie. It is technically advanced, traditionally constructed and finished at a level that makes the chronograph mechanism itself a large part of the experience.

The 1815 Chronograph 414.028 is perhaps not A. Lange & Söhne's most complicated watch. Nor does it need to be.

It shows instead what happens when one of the world's most uncompromising watch houses takes one of watchmaking's most classic complications and carries it out in its own way.

And for anyone who wants to understand A. Lange & Söhne beyond the Lange 1 and the Datograph it is hard to find a better model to start with.
