^^^^I think there is a reason why this is a concept only. Personally I don't see the point, especially if the case is like 39mm, just looks odd in my opinion. Nevertheless I do think the movement itself looks quite nice visually.
I think the 'star' seems to be this bad ass triple split Lange - totally unnecessary, but just look at that movement! It also seems a bit of a bargain at $147,000 (this is in relation to some of the tat being released above the 6 figure mark....)
