I believe there was no leather wallet with this packing. I think your piece is quite early based on your card type, But I can't tell exactly without the serial number.
I think the seller got a NOS from the AD. Based on the box and card type, this piece should have been shipped to AD before 2017, but it never got sold or registered until 2021. All pieces from Journe after 2017 are coming in the small square box. Hope that helps answer your concerns.
We have to follow the rules and wait...... Did you see the guy got 3 steel Aqu from the oldest AD (Central, HK) in 1 week on Nov. 2022. They dated the certificate 3 continuous day in a row. That looked so bad for that famous AD.
I was at Christie's auction preview and saw this 5726/1A under double seal. The sales date is FEB 2023, less than 2 months old. Does Patek allow this double-seal practice again? [Commercial link eliminated — FabR (moderator)]
