Lack of perlage on the lower levels near the remontoir? Or abruptly halting bevel?
I don't see what else there is :0
On mine. But ...
I believe, given a strong enough microscope and enough time, similar things can be found on others as well! 😄
What I think, too. Montblanc, with Villeret, some Indies, super high end Patek and Vacheron, probably, Chopard and Ferdinand Berthoud... Not many more can compete.
Lovely 😍
Thanks for sharing...certainly a very appealing alloy with which to make movements. I can't wait to see how mine develop patina over time...lol
Well
About Brass :
One of the enticing characteristics of brass jewelry is its gold-like appearance. Depending on copper-zinc ratio, the color of brass may range from dark brown to silvery white. To achieve a gold-like shade, you must combine around 67% copper and 33% zinc. Thanks to this unique property, brass is often used as alternative to gold for a variety of design applications.
With copper as its base constituent, brass is among the most durable metals around. It can last for thousands of years if properly stored and maintained. As previously mentioned, brass develops a layer of greenish material on its surface. This layer, called patina, acts as a shield that protects the brass inside from corroding
Brass is significantly cheaper than premium-grade base metals such as German silver, sterling silver and gold vermeil. Part of the reason is its main components—copper and zinc—are still currently in great abundance. Unlike gold and silver, they are not precious metals. Another reason is that brass is used for familiar applications like construction and electronics.

So you are saying that Lange is promoting german silver while Jaeger Lecoultre pretends it is not qualitative enough?
I'm not saying that...
I just note that JLC is abandoning the German Silver on the latest Duomètre and that at the same time ALS - which belongs to the same group - is still promoting this finish....
Yes, that is strange, very strange. Unless Jaeger Lecoultre thikns that Lange is taking the wrong way with their cheap german silver movements...
They're not even close to a contradiction.
Cf. their discourse on the duometer movement, which was perfect balance with few complications, and then, thanks to the Helvetic holy spirit... that's no longer the case, and you can add all kinds of stuff without affecting regularity....
