Lange & Sohne Cabaret Platinum.
This Cabaret is in my Lange Top Five, along with the Datograph first generation, the Langematik Anniversary, the 1815 Moon Phase Emil Lange and the Lang One Platinum Black Dial, in this order.
The Cabaret is another watch, a very special one, with its rectangular case, but so Lange from the front side to the back side.
Here are some pictures I found on the net:
