Zenith El Primero Rainbow Flyback
Happened to me once. The reason being, seller didn't filled the forms needed properly 
Yes, at the same exact location Chicago
As a result, my shipment was delayed for 1 week++
insisted the seller to do follow-ups, demanding explanations from USPS (email & calls), Custom Office asked the seller to declare actual value or they'll ship it back to seller at seller's expense. In the end everythhing was properly done and met. Luckily happy ending one. Hopefully the same ending for yours 
p/s: as long as you 'buy the seller' everything will be sorted out with due care. Keep the faith bro 
Seller has impeccable record so I am not worried.
He did contact USPS to get things sorted out and apologized for the delay.
In the end, as long as I got the watch... I am all good...
Zenith El Primero Rainbow Flyback
Nice watch, hope it gets sorted out soon so that we can enjoy the pictures.
It is a smashing watch... one that does not appear often in mint condition.
Once I saw it for sale... there's no turning back.
My plan was to get a GMTIIc for CNY but due to the low bonus I got this year... I don't have that kind of money to spare...
The GMTIIc will have to wait...
As for the shipping delay... wait until neck oso long liao... lol
