Six A Lange & Sohne, one Lang & Heyne Friedrich lll and one Moritz Grossmann Atum 37. I do not have any of the A Lange & Sohne watches as they have all been disappointing although the movement finishing has not been the problem. The Lang & Heyne is one of the rare German watches not adopting a German three quarter or two thirds plate that make A Lange watches heavier than its rivals. The open worked finishing is one of the most attractive manual movements money can buy. I have since sold mine only because I want another Friedrich lii with customised Louis XV hands instead of the spade hands.
