Since I am not a Lange technician ...
... I had to go into the text passage again to read about it.
The whole swinging system is made out of several pieces that have to be assembled together.
The notch in the regulator part will be like a spring as the component with the pins holding the balance spring has to fit into the regulator ring.
And as it has to stay in the regulator ring with a certain degree of friction, the notch will widen a bit when it is pushed in: hence it acts like a spring.
The notch is in any Lange movement, in any other movement in any other watch also that uses this way of adjusting the spring.
Nothing wrong there.

What is the purpose of the 'notch' in the swan neck regulator?
Hi all, First of all, please forgive my lack of technical knowledge and for potentially screwing up the terminology. Now to my question: What is the purpose of the 'notch' in the regulator of ALS watches? I have highlighted this notch in the following two...
I assume the "notch" makes it a spring
I guess during assembly the notch will be opened a bit, bend a bit to put all into place and to hold it securely after wards. There is nothing wrong with your lovely Up and Down ... a very nice 1815! Best Moritz
Hi Moritz,
Thanks for your reply. It's interesting what you say about it being a sort of spring, or a least a means to widen and loosen the part to allow for fitting. It makes sense. It would be nice if an expert could confirm or deny this. :) Thank you also for the...
Ok, ok: YOU asked for technicalities :-)
The whole thing is called swan neck regulator. On the first pic you see the lever pointing to the left. The little screw in the bottom will move the lever (called "Ruecker" in German) up if you crew in and down if you crew out. This movement has also on i...
Uh oh, I'm a little confused now. :)
To be clear, I do understand that the regulators in ALS watches use swan necks, and I do know what a regulator is for (it adjusts the effective length of the hairspring). However, I don't understand what you mean by this: "This movement (of the lever) has...

Thank you!
Moritz, thanks for your patience in explaining and confirming the function of the notch to me. Much appreciated. I have looked at my watch's notch again with the 10X loupe and it is definitely crooked/jagged around the edges (like in my artists rendition)...
Dr Monet's advice: look at other close ups here
Simply enter " Lange close up" into the Forum Search function here and tick "images" first. You will see: it is all fine, all of them have got it. I could see it even with my bare eyes in my 1815 homage moon phase! One more interesting note: if you compar...
Oh yes, I understand that all the watches have the notch...
...I don't dispute that, it is plain to see in many photos of ALS watches. However, if the notch is supposed to be straight and well-finished, as it seems to be in SteveG's high-res photos of both his 1815 and L1, mine is not. Mine is cosmetically damaged...
