In this insightful post, aviya invites readers to explore the intricate 'engine-side' of his A. Lange & Söhne collection, offering a detailed, movement-by-movement tour. His personal reflections and technical observations provide a unique perspective on the calibers that define Lange's horological artistry. This deep dive into the brand's engineering and finishing showcases why these movements are revered by collectors worldwide.
Okay, so: here's the engine-side of my Lange family!
Let me introduce you to them, from left-to-right:
We begin with the gorgeous L951.5. Of course, the base L951.1 "Datograph" caliber shook the entire watch industry upon its release in 1999 - "The shot heard around the world" (well, certainly in Switzerland...). Along comes a quirky German start-up and - suddenly - drops this exquisite, manually-wound, column wheel chronograph with a fully-jewelled lateral clutch. Its architecture is just so, so pure and rich and sweet: I never tire of looking at it nor louping it - nor listening to it ticking at its stately 18,000bpm!. This .5 variant also has a Lange in-house balance spring. And then there's the movement materials - German silver (not brass) plates and a steel chronograph mechanism - and hand finissage of every component. The quintessential Lange palette of complimentary colours, the abundant flat-polishing - the hand-engraved balance half-bridge. And that now iconic Lange chronograph clutch lever (look carefully and you will find it in all manually-wound Lange chronographs: yes, it's in the Datograph Perpetual Tourbillon - and even the Triple Split!) with its inward and outward sharp angles, straight-grained face and immaculately hand-bevelled edges - that is not easy to do, particularly in steel! I was honoured to meet Annegret Fleischer on one of my early Manufactory visits - her life's work includes designing an absolute masterpiece.
Then, we take a breath and move on to the L051.2. If you zoom your eyes in on the technical relief of three-quarter plate, you'll observe that it's extremely complex in this caliber (compared to the L051.1 to its right); with the exposed winding and power reserve train, and its seven (7) screwed gold chains. It somehow looks "sharper" to my eye (I've actually got a great individual photo coming up in a future post that amplifies this effect). The half-bridge is also in a different position and rotation in order to accommodate the plate around the power reserve and the larger barrel. This caliber is quite the visual treat with the violet of the many pivot jewels, surrounded by glinting gold chatons held in place by those familiar cornflower blue screws. The movement features Lange's in-house balance spring too, plus 72-hours of power reserve from a single barrel. An endlessly delightful, functional movement to look at and appreciate every time I see and wear it.
The L051.1 is next. Simple. Sweet. Superb. I said in my immediately-previous post that I wished Lange had exposed the winding train of this caliber and I still do: that would have nicely echoed their pocket watches of yesteryear. That said, without it, we get to see more of the three-quarter plate and the beautifully textured Glashütte ribbing - unimpeded. Again, this one - and its predecessor, the L941.1 - was my jumping off point into Lange watches and so it will always hold a special place in my heart. The L941.1 was the first caliber that I actually held in my hand that clearly featured what we all now recognise as "Lange's DNA" - and the L051.1 retains that (and improves upon it technically). The subsequent revisions - the .2 for the Up / Down and the .3 for the Annual Calendar - spawned from this caliber, and sometimes the more complex things get the more you appreciate the purity of the original.
And so to the L041.2 in the Richard Lange - the other bookend of my collection. This is a thick and solid caliber in the best German traditions of first being engineers of things that work! I've extolled some of the surprising technical virtues of this movement in a previous post. It is also equipped with a Lange in-house balance spring - just the second caliber to do so after the L001.1 in the Double Split. It has a comparatively short power reserve of 38-hours with a stop-works, which most Lange movements of its generation had - including the L001.1 and the L951.1 (which actually only had 36-hours). But it is my most precise Lange by daily rate and beat error: its rate is really, really stable - on and off wrist. Compared to the L051 family, it feels like you're winding a more substantial watch - and that's because you are. And the elaborate raised and bevelled centre-seconds bridge only adds to that vibe.
"Which one of your children is your favourite?" Easy: they all are!
Enjoy.
PS: I also included a second photo so you can be reminded of what their faces look like too. ;-)
With my continued warm wishes, aviya.
