The case for it

Useful travel mechanics, strong brand recognition and broad service support create one of the clearest value cases in Swiss GMT watches.

What goes wrong

Date-change history, case thickness, bracelet wear, warranty and complete links require careful inspection.

Who it fits

Best for someone who wants mechanical GMT utility and accepts a large, thick sports-watch footprint.
