The MTM Grey Air Stryk I, shown above in sandblasted gray with red dial, is an analog-digital watch that serves many tactical functions. Its electro-luminescent backlit display windows can be preset to show one of 58 time zones, used in chronograph mode, a stopwatch mode, and more. Its stainless steel case offers full protection underwater up to 660 feet/200 meters and on land. The anti-reflective and scratch-resistant sapphire crystal glass with ultraviolet protective coating also helps in this regard.
