Ikepod Dual Time or Breitling Aerospace
Having only ever lost watches when traveling overseas, I tend to take one that doesn't cost an arm and a leg.
Similar to the Parmigiani, the Ikepod can be set to any time you want in either time zone.
It shows the date. You don't have to be a rocket scientist to figure it out. It's comfortable and $1500.
Downside - only available as used watch, and no lume. Funky strap or a nice bracelet.

Alternatively, do like many of us and get a Breitling Aerospace and use the hands for one zone and the display for the other.
I think you can set the time differently in each of the two zones (I mean I think you can do it intentionally; I do it by accident frequently).
You do have to be a rocket scientist or have the manual for at least the first few times you change it.
