I have a Casio Oceanus with many of these features.

Titanium, solar, satellite and iPhone syncing.

Casio says it can adjust to 45-minute time zone differences like in Kathmandu.

My favorite feature is using the second time zone dial as a chronometer. Natural and fast to read 4:15 pm as an elapsed time of 16 hours 15 minutes.

Mine is model OCW-T4000C-3AJF. Reminded me enough of the cool Rolex Milgauss but way cheaper and more functional.
