Just to close the loop here, it took me a year but I bought one new and absolutely love it!
Just as importantly I really enjoy the story how I got it:
Last month I was in Tokyo for work and a number of colleagues had impressive mechanical watches: Panerai, Hublot, IWC etc.
One of them referred me to a shopping center near Nakano station where there are loads of watch shops. New, Used, various brands etc.
I wasn't specifically planning to buy anything that day but I found a suuuuuper low price at this store called JackRoad.
Duty Free brought the price further down another few hundred dollars.
The manufacturer's 5 year warranty is honored globally.
I couldn't be more pleased.
The presentation box hardly fit in my luggage on the return flight!
Nakano station was pretty nuts.
They had this daytona on display like it was nothing. No security or anything...
To save you the calculations, 27,727,273JPY is over $250k
and that wasn't even the most expensive on display
(The most expensive one was a boring looking patek but surely had a good amount of history associated with it...)
