LONGINES Spirit Zulu TimeL3.802.4.50.6

This is the steel baseline of the Zulu Time GMT — same black ceramic bezel, same manufacture automatic caliber, same 100-meter rating as the titanium version, just built in a metal that adds noticeable wrist weight at 42mm. I don't count that against it: a steel bracelet GMT has a substance to it that titanium trades away, and plenty of buyers want that heft as confirmation of value. The dual-crown GMT setup is genuinely functional rather than decorative — you can set the local hour hand independently without disturbing the running seconds, which is the detail that separates a real travel complication from a fashion GMT. At this price point, steel-and-ceramic is the more common spec, and it's the one I'd recommend if cost matters more than ounces.
