Spirit Zulu Time

Full titanium — case and bracelet both — is the detail that separates this Zulu Time from the steel versions I've also catalogued, and it's the one that matters most on the wrist: a 42mm GMT this size in steel starts to announce itself, while titanium disappears. The black ceramic bezel adds scratch resistance the caliber doesn't need but the daily-wear case does, and the manufacture automatic movement drives a proper GMT function rather than a simple second-time-zone hack. At 100 meters it's rated for real travel use, not just the desk. Among the Zulu Time variants, this is the one I'd choose if I were optimizing purely for wearability over cost.
