What is a GMT Watch and What are They Used for?
A GMT watch is a timepiece that features a display for two distinct time zones. It is a highly practical accessory for individuals who travel frequently or have loved ones residing in different time zones.
While GMT watches often have a similar appearance to a diving watch, the additional feature of the bezel serving as the second time zone sets them apart. Alternatively, certain GMT watches feature an alternative design, in which a second hand on the dial represents the second 24-hour time zone, providing the ability to view two time zones simultaneously. Due to their distinctive design and functionality, GMT watches are increasingly sought after by collectors.
What Does GMT Stand for?
The acronym GMT stands for Greenwich Mean Time, which refers to the average solar time at the Royal Observatory in Greenwich, London. This point served as a reference for all other time zones until the introduction of atomic clocks in the 1950s. The reason these watches are referred to as GMT watches is due to their ability to display the time based on Greenwich Mean Time.
How to use a GMT Watch
To operate a GMT watch, you will first need to set the primary hour hand to the local time. Following this, set the 24-hour hand to the present GMT time. The 24-hour hand rotates once every 24 hours, enabling you to keep track of time in multiple time zones. If you need to adjust the watch back to local time, move the main hour hand back to its original position. In the case of a GMT watch where the second time zone is represented on the bezel, you can simply adjust the second time zone by rotating the bezel, much like with a diver’s watch.
Why Would you Need the GMT Watch Function?
People who purchase watches seek GMT pieces for various reasons. The aviation, naval, and military communities use GMT to calculate longitude and time zones, making it especially important to them. Additionally, travelers find them very useful to keep track of both their home time and local time.
GMT watches are not only favored for their practical purpose, but also for their iconic design, which appeals to enthusiasts. The Rolex GMT-Master II, known for its striking 50/50 colorway on the bezel, is one of the most popular models of GMT watch available and has set the standard for GMT watches ever since its release.
