Of course, it is a nice watch with a beautiful movement which follows the case shape. But IMHO, when you already have a Cabaret, I would prefer to go to another Lange. Why?
Because the Arkade and the Cabaret share some common points, the most obvious one is that they are not round...
Because the movement is very similar
Because I find the Cabaret easier to wear due to its more classic shape...
You will find pictures of the Grand Arkade here:

But if you are attracted by its originality, it could become an irresistible watch...
