The Colt Automatic watch embodies its military roots with a rugged design. The bezel is satin-brushed and has four rider tabs for easy handling and protection of the sapphire crystal, which is glareproof on both sides. The dial comes in black, blue, or silver with a raised circular motif. The steel case is polished and can withstand water up to 200 meters. The crown is screw-locked and reinforced for added protection. Inside, a self-winding movement is chronometer-certified. Look for model A1738811.C906 with a Mariner Blue dial.
