This is absolutely not true.
Tobel Im not sure how familiar are you with the nautilus buyer. The nautilus in the 2012 was in the €19K range. 5711buyer is not a collector at least no more, it has become a sensation like the daytona.
A true collector hunts and pays premium for 3700 (without a service dial) vintage chronos ecc. Patek always valued collectors, and believe me if one of this (at least this who i know ) wants one, they will get one at retail in 1 year time frame and not 8. So you want to show off pay what market demands, but the right price to pay until patek still produces its 29800 USD.
