Since 1989, the U.S. Army has specified the use and manufacture of this type of self-emitting illumination for its timepieces to ensure that soldiers can read their watches in the blackest of night. Bright blue Trasers mark the hour, minute and second hands, as well as at the 1-11 hour positions. Green and orange Trasers mark the 12 o’clock position. Made to the highest military standard from the very best materials, this is the same watch currently used by many US police forces, the British Special Air and Boat Services, US Navy SEALS, the French Foreign Legion and other leading specialist services throughout the world. Swiss made with superbly accurate quartz movement. Lightweight, rock-hard carbon fiber case with mineral crystal and moisture-wicking band. Water resistant to 100 feet. 1.25" face dia.
