The Colt Automatic watch was originally designed for military use, and its tough style reflects that heritage. The bezel has four tabs for easy handling and protection for the crystal. The dials come in black, blue, or silver with a raised circular pattern. The steel case is polished and can resist water up to 200 meters. The crown is screw-locked and reinforced for extra protection. Inside, you'll find a self-winding movement that has been certified as a chronometer. The reference A1738811.C906 has a beautiful Mariner Blue dial.
