The Colt Automatic watch's rugged design pays tribute to its military roots. Its satin-brushed bezel boasts four rider tabs for easy grip and protection for the scratch-resistant sapphire crystal. The black, blue, or silver dials feature a subtle raised pattern. The sturdy steel case, with a screw-locked crown and water-resistance up to 200 m (660 ft), houses a self-winding movement certified as a chronometer. The model A1738811|BD44 comes with a sleek Volcano Black dial.
