Currency fluctuations is not the real reason: Patek and all other luxury item manufacturers from Switzerland simply insist on theire margin/profit.
The Pound Sterling has lost up to 25% in 2008 against the Euro, but German cars did cost the same.
No, no.
Watches have always been luxury items: a Patek, a Lange, a VC ... always!
What these companies do is simple: they have created a modern myth by using advertising companies (which was very costly) and believe still that this will keep the myth alive.
Possibly, but only for a much, much smaller group.
But it is also theire own fault: I have seen Patek advertisements in quite small airports, low budget airports ...
To give an answer to Bruno: all Pateks are far too overpriced.
