GMTs under €2,000

A GMT adds a fourth hand that travels around the dial once every 24 hours, pointing at a second time zone on the bezel or chapter ring. It's the most useful complication for anyone who travels or works across time zones — and the most satisfying to set.

One detail worth checking before you buy: on some GMT movements the 24-hour hand is the one you adjust independently, on others it's the local hour hand. Frequent flyers usually prefer the second kind.
