[Source] Death Watch Armor was the armor worn by a break-off of Mandalorian warriors, the Death Watch by 60 BBY. The armor was made of beskar, a metal found on Mandalore, the homeworld of the Mandalorians, which made it almost indestructible. The Mandalorian helmet itself was unique to the Death Watch and consisted of a black, T-shaped visor with a complex heads up display.
