GMT watches are timepieces that feature an additional hand or sub-dial that displays a second time zone. The GMT (Greenwich Mean Time) hand or sub-dial allows the wearer to easily track the time in two different time zones simultaneously.
GMT watches were originally developed for pilots and travelers who needed to keep track of time in multiple locations, but they have since become popular among watch enthusiasts and anyone who frequently travels between time zones.
Many GMT watches also have a rotating bezel that can be used to track a third time zone or as a timer for various activities. Some GMT watches also have other additional features such as chronograph functions, date displays, and durable materials like stainless steel or titanium.
GMT watches come in a variety of styles, from sporty and functional to elegant and dressy, making them a versatile addition to any watch collection.
