Designed to suit the needs of the business or adventure traveler, the Aeromarine Colt GMT offers excellent precision and durability and ruggedly handsome styling. The solid steel case highlights a highly legible blue dial with luminous hands and markers, large applied Arabic numerals, and a date display at 3 o'clock. A notable feature of this watch is the red-tipped designated GMT hour hand, which corresponds to a graduated 24-hour scale, indicating Greenwich Mean Time, or the time at zero degrees longitude. This clear and efficient display enables quick and accurate calculations to determine the time in any region of the world, without risk of confusion between a.m. and p.m. The dial is capped with a scratch-resistant glareproof sapphire crystal and framed by a unidirectional rotating bezel for recording elapsed time. The Colt GMT is skillfully designed for pressure and shock resistance, and it features a screw-in crown and screwdown caseback for water resistance to a full 500 meters. It's outfitted on Breitling's triple link steel Professional II bracelet and powered by self-winding caliber 32 automatic movement.
