The Colt Automatic's tough design pays homage to its military roots. The bezel, brushed for a satin finish, boasts four rider tabs for easy use and protection for the glare-proof sapphire crystal. The black, blue, or silver dials feature a subtle raised pattern. The case, made of polished steel, can withstand depths up to 200 m (660 ft) and has a screw-locked crown with added defense. Inside, a self-winding movement keeps accurate time, certified as a chronometer. Look for the A1738811.G791 model with a sleek Stratus Silver dial.
