Hi mini,
I am not sure why you said there is no 5980 or other hard to find watch in US or EU. I personally don't know what is going on in EU, but as far as US, there have been plenty of shipment of 5712, 5980, 5960 to US. The ONLY reason you don't see them in AD is because they already presold to the AD's loyal customers who may have been waiting for 1-2years. If you read some of the past post in this forum, you can see some members showing us their new purchase of 5980 and 5960.
I personally knew my AD did receive 5960, 5980, 5712 in the last few months, more than once.
I also got a 5980 and 5712 from my AD after being on waiting list for over a year.
So, Patek is shipping these watches to US, but you will not see them in AD.
The Natulius you saw in Thailand may be just their regular stock since your picture only show a couple watches, not a big deal.
