The Avenger II GMT has a super useful 24-hour second timezone display and a rotating bezel that lets you keep track of a third timezone. Its self-winding movement is officially certified as a chronometer and is safely housed in a tough steel case that can handle depths of up to 300 meters. The crown is sturdy and easy to grip for smooth control. The stencil-style numerals give it a cool, aviation-inspired look. Check out reference A3239011|C872 for a sleek Mariner Blue dial.
