I think Patek started this a while back. Watch Amateur? Where do we draw the definition? Imagine one day you walk into a watch store and before you can make any purchase, they need to do a thorough background check including your current net worth, your criminal record, marital status, traffic viola
and the interpretation is rather unique, IMHO. The perpetual calendar mechanism is very delicate, to say the least so make very sure it's fully operational. I have the same watch in WG and a custom blue dial.
However, w/ commercial interests behind, I can imagine biased decisions made in exchange for short term gain. With JL at helm for the Richemont group, hopefully we can start to see some decisions planned w/ longer vision.
