The Colt Automatic is a rugged watch with a military background. Its satin-brushed bezel has four rider tabs for easy handling and protects the sapphire crystal, which is glareproofed on both sides. The dial comes in black, blue, or silver with a raised circular design. The steel case is polished and can withstand water up to 200m (660ft) with a screw-locked crown for extra protection. It also has a chronometer-certified self-winding movement. Check out the A1738811.C906 model with a Mariner Blue dial.
