Experience the bold Uzi Mens Watches design in a powerful new watch, The Titanium Defender. This wrist watch is super lightweight, but 40% stronger than stainless steel and is up to any task or situation, under deep water to the top of any mountain, scorching heat of the deserts of Iraq to the cold of the Artic. The Uzi Defender Titanium Mens Watches are the toughest watches ever made by Uzi. The Defender Tritium Mens Watch is the easiest in the world to read in low light conditions. The light emitting devices require no battery power or any other form of charging. Tritium watches are equipped with a tritium light source. These tiny airtight vials sealed under pressure are resistant to water, oil and most corrosive materials. A minute quantity of tritium lights up the dye. They never need servicing or maintenance. The Tritium self-illumination system gives button-free illumination with an astonishing 25 year life span. Every aspect of Uzi watch construction, from the high quality Swiss component movement to the 200-meter water resistance, is built to ensure trouble-free performance.
