The A-11T Americana was inspired by WWII U.S. Military issued watches. Painstakingly combining authentic details with our rugged U.S. Patented 42 mm titanium case... to create a high performance classic field watch that can only come from the leader in titanium field watches. The A-11T Americana is built with only non-compromised components including: scratch resistant sapphire crystal, screw down back & crown, precision all-metal jeweled USA assembled movement, super luminous hands & markings and a 200 M water resistance rating.
