Hello all,
Here are two pictures I received from a friend, who, btw, requested to stay anonymous.
Front: 
And back:
And a question: ""Is the Patek "worth" twice the price of the Lange?""
If you search the (incredible!) Antiquorum website, you will find two Patek 5565´s being auctioned and fetching approx USD 42K and 45K
A similar search for the Lange learns that the Jubilee´s auctioned sold at approx. USD 15K ~ 18K
So, two watches, very different but very similar as well, but worlds apart according to the prices fetched at auctions.
Love to hear your opinion(s).
Edwin
