At Breitling, the name Colt stands for a range of products characterized by exemplary ruggedness and reliability. These properties are clearly apparent in the Colt GMT, an abbreviation of Greenwich Mean Time, or zero degrees longitude. This watch is distinguished by the fact that a second timezone is indicated by an additional hour hand associated with a 24-hour indication. Discreet but efficient, this hand enables clear and precise read-off of a timezone without any risk of confusion, such as between 4 am and 4 pm. Thanks to its dedicated architecture, it provides increased resistance to pressure and to shocks, with an overall water resistance of 1,650 feet (500m). These qualities make the Colt GMT the winning model in its product category.
