Here my humble chip-ins:
Geophysic Universal Time - charme & utility.
MIH - just the essentials, but including a Chrono;
Unobtrusive, pure yet really cool..
JLC Master Moon - still a classic.
JLC Polaris Geographic - a multi-purpose travel companion;
Rolex GMT 6542, a vintage treasure for me (1958) - has it all..
Breguet Marine 5817 - love the Guilloche, a “GADA” watch ( Go Anywhere, Do Anything).
