The Colt collection from Breitling is known for its tough and dependable watches. One of their standout models is the Colt GMT, named after the Greenwich Mean Time at zero degrees longitude. This watch has a special feature - an extra hour hand that shows a second timezone on a 24-hour scale. It's a subtle yet effective addition, making it easy to read the time in a different timezone without any confusion. Plus, it's built to withstand pressure and shocks, and can even be submerged up to 1,650 feet (500m) underwater. It's no wonder why the Colt GMT is a top choice in its category. Model number A3235011/C642.
