A very underrated Annual Calendar imho. Here’s some trivia facts: Number of parts in the Saxonia AC: 476. Number of parts in the Langematik Perpetual: 478. Seems to me like the movement of the AC is a a derivation of the QP. Best, Ian ...  

I remember seeing this watch when I was new here. It's been a few years and I remember you like blue dials. I bought a Lange Perp way back but since replaced it with a PP Perp.

I especially love the legibility of the dial, and the simple lay out. A Lange watch maker told me that making the AC is as hard as making the Langematik Perpetual. Real bang for the buck imho. By the way, how are you? Best Ian

I hope all is well with you too. Still buying watches so I am still infected with this bug

Gorgeous movement with the two piece micro-rotor.. and as you said it is essentially the perpetual movement but without a few parts. However, to my eyes, the dial is more elegant and balanced. Also, the thickness is impressive. I think this is one of the ... 

everything about this watch is gorgeous. THIS is how you design a dial. If I could find one NOS I would be sorely tempted. Perhaps it's time to begin a search : )

When the Langematik Perpetual was introduced back in 2001, it was available in YG and PT only. Then, about 5 years later, Lange discontinued the YG version and replaced it with RG. The YG is truly stunning.

I recall someone asking Lange years ago if the Saxonia AC movement was identical to the Langematik Perpetual movement except with 2 fewer parts due to the lack of a leap year mechanism. I believe Lange's answer was that the explanation is more complicated...
