GMT / Travel Watch

A GMT watch has a fourth, slower hand that completes one rotation every 24 hours, pointing to a second time zone on a 24-hour scale or bezel.

A caller GMT lets you set the GMT hand independently — ideal for tracking a time zone where someone you call lives. A flyer (true) GMT lets you jump the local hour hand independently, perfect for travel: change local time without stopping the watch.

1. 1On a flyer GMT, pull the crown to the first position.
2. 2Turn to jump the hour hand in one-hour steps to local time.
3. 3The minutes and GMT hand keep running.
4. 4Push the crown fully back in.

1. 1Pull the crown to the final position.
2. 2Set the main hands so the 24-hour GMT hand shows your home time.
3. 3Then adjust local time with the date-position quickset.

Set the GMT hand to home time and leave it. On arrival, just jump the local hour hand to the new zone. Use the rotating bezel (if equipped) to track a third zone.
