GMT / Worldtimer

Second-timezone via 24-hour hand and bezel (GMT) or 24-city ring (Worldtimer). The traveler's watch.

The GMT-worldtime style combines dual-timezone or full-worldtime indication with a sport or tool aesthetic. The 24 catalog references include the Rolex GMT-Master II (126710BLNR "Batman", 126710BLRO "Pepsi"), the Tudor Black Bay GMT, the Omega Aqua Terra Worldtimer, and the Grand Seiko SBGE271. Most buyers use the GMT function as a day/night indicator for a home timezone, the complication handles travel but is genuinely useful on any wrist that needs to track two locations. For the mechanical specifications (true-GMT vs. office-GMT, one-way vs. two-way bezel, 24-hour hand independence), see the complication/gmt landing page.
