A. Lange & Söhne Updates a Grail Watch

I occasionally find myself looking for a good excuse to write about some of my favorite watches, as doing so with some context feels too self-satisfying. This excuse can be a guide, a group editorial, or, as in the case today, a marginally new version of an existing watch that I adore, but haven’t had the chance to divulge my feelings on adequately. That watch is the A. Lange & Söhne Zeitwerk, as today, Lange has announced the Zeitwerk Date in rose gold. While certainly exciting for people who said, “If only this watch came in rose gold” as a topic for a whole article, a new case metal is a bit lacking. Conveniently, I have a lot to say about the Zeitwerk in general.

There was a time not that long ago when asked what my “grail watch” was, my default answer was the A. Lange & Söhne Zeitwerk. Why? Few watches mix the classic and the contemporary quite so well. They’re unique, handsome, and ooze tasteful luxury. They aren’t blingy or ostentatious. Additionally, nearly any watch enthusiast appreciates them, so it was an answer that didn’t require much explanation. However, as my knowledge of watches has grown, another aspect has emerged that I find fascinating: the complexity it takes to create something that seems so simple.

If jump hours are a rare complication, jump minutes are unicorns. The only other I’m aware of is the IWC Tribute to Pallweber. Although the idea seems simple enough, making a disk jump once a minute, two disks every ten, and three disks every sixty requires a lot of power. Sudden draining of power from a movement can negatively affect amplitude and power reserve, thereby impacting the overall accuracy and reliability of the watch. Additionally, using a lot of force to jump disks has the potential to damage a movement if not calibrated properly. So what’s a brand to do?

In the case of Lange, it’s to create an absolutely bonkers and gorgeous caliber with various tricks up its proverbial sleeve for handling these issues. While there are many idiosyncratic concerns with jumping mechanisms and displays that Lange addressed, which can be read about here, the issue of power management was dealt with a constant force mechanism, not only storing and providing power for the jumping disks, but for the escapement as well, creating an exceptionally accurate timepiece with consistent amplitude.

Lange achieves this through the use of a patented remontoir, which, in terms I find digestible, is essentially a tiny secondary power reserve that sits between the mainspring and the escapement/complication. Its reserve is filled by the mainspring, and is then fully released in bursts at fixed intervals, which happens every 60 seconds in the Zeitwerk. They also utilize a “fly governor,” which is not a cool politician but rather a small spinning device commonly found on minute repeaters, to dissipate excess energy and protect the mechanism.

Like I said, not so simple. And yet, from the dial side, it’s pure elegance… Okay, it’s pure elegance from both the front and the back. Like all Lange calibers, the L043.6 caliber is crafted from hand-finished German silver and features hand-carved balance and escapement cocks, as well as a distinctive bridge that spans the constant force mechanism. Langes exemplify “business in front, party in the back” for horology.

Back to the dial, the Zeitwerk looks like no other watch. It’s nearly symmetrical across the vertical axis, with an hour window on the left, minutes on the right, power reserve, and a massive subseconds down the middle. A screw on the left is mirrored by a clear and transparent sapphire on the right, which sits atop the pivot of the minute disks. The hour and minute windows, as well as the sub-seconds, sit within a brushed plate that adds an unexpected industrial touch, complementing the more traditionally styled serif typeface used for the numerals.

Initially time only, Lange gave the Zeitwerk an unneeded but certainly exciting additional complication in the form of a minute repeater in 2015. As though the Zeitwerk weren’t already easy enough to read, now, at the push of a button, one could just listen to the time. Ah, that luxury lifestyle. Although a flex, it wasn’t until 2019 that the Zeitwerk received a practical upgrade, doubling the power reserve to 72 hours via a double mainspring and adding an independent hour pusher for more convenient time setting. Lange also took the opportunity to launch a new version of the Zeitwerk that included a digital date, which, to my sensibilities, is the perfect form of the Zeitwerk, at least in function.

Powered by the L043.8, which now has to jump four disks every 24 hours, the aptly named Zeitwerk Date features a glass ring encircling the dial, with 31 numerals as voids set against a light gray plating. The current date is highlighted in red below. Easy to read, the design complements the digital concept. The only downside is that to accommodate the peripheral date, the case has grown from 41.9mm to 44.2mm. Nothing comes without compromise.

As of today, the Zeitwerk Date is available in both rose gold and the original white gold. The dials, made of 925 sterling silver and rendered in an appealing palette of grays, are identical save the hands, which match the case. It looks great, of course. It’s rose gold and gray; these things work together.

After completing this little exercise, I realize that if someone were to ask me what my grail watch is today, despite having many more options in my head to choose from, depending on perhaps the weather or my mood, the Zeitwerk or Zeitwerk Date are still viable options. And while all the reasons I initially had are still valid, there is something else that I now find appealing.

Similar to dead-stop seconds, a fully mechanical, jumping digital display is not without a touch of horological irony. Though rooted in celebrating the clock within the Dresden opera house, that this mechanically advanced, miraculously complicated, and utterly luxurious timepiece displays time in the same visual fashion as many watch fans’ first watch from when they were a child has a charming humor to it. Intentional or not, as someone who strives to never take themselves too seriously, finding this sliver of amusement is a rare and lovely quality. A. Lange & Söhne
