For those who are not or cannot be at SIHH. Neither am I 
Here are some photos of the apparently Lange's top-of-the-line Novelty of this year.
Lange 1 Tourbillon Perpetual Calendar.
I assume that many of you can see these photos and press release via Lange's web site, but for unknown reason, some countries including Japan cannot see it - the server that serves those regions are replicated from the main server with one day delay. I got these from other source 
Here you go.

PT is LE of 100. Also available in PG
Size=41.9mm


Month indicator is in the inner bezel.

Caliber is based on Daymatik's and automatic tourbillon. Yes, you read it right, AUTOMATIC.
Power reserve=50 hours.
Other novelties will appear here sooner or later, but thought you would like to see the top of the line first.
