Many brands not just Lange fail to realise that a large complicated piece id difficult to sell especially when one attaches a high price tag on it. I am not saying the work that has gone into the watch does not justify the asking price but it makes us collectors ask the question what else can we spend 500k euros on. Apart from a number of Ferraris I can think of, a nice home would not go amiss. Yes there will be a few mega rich collectors who would happily buy the box set but as these watches were launched 17 months ago, they should have been snapped up by now. The fact that a few still remain unsold demonstrates that Lange should have either produced fewer Tourbograph models or reduced the number of box sets. The ultra thin and Rattrapante were always going to be the popular models.
