How does the world time works? Can it display one zone with the hands and another one with the display? Or is it a zone at a time?

Yes you can display two time zones at once. The hands will always display your selected home time zone and then you can also show any other time zone on the little lcd screen digitally as well. Also very easy to scroll through all time zones on the screen

how long did it take for delivery in the US?

2-3 days if I remember correctly. EMS service is extremely reliable if that’s how shipped.

Does “Japan import” mean it was manufactured - including case - in Japan?

The movement is made in japan but the watch itself is built in thailand.
