Based on how much these two watches get talked about they are most likely the least popular of the Langes. But, never fearing to walk on the path less traveled, I bought them anyway and could not be more pleased. I've had the 1815 Ab/Auf for a few months now and just recently (a little over a week ago) took possession of the Cabaret Moonphase.
Neither watch is large, but they each fit my thin wrist remarkably well. So far I have found only one problem with Lange watches. They are addictive. One is simply not enough.
