These were made with specific enhancements that set them apart from their civilian equivalent. The reference 5513 was the first of these to be customised for Military use by making the spring bars solid and friction welded into place negating the possibility of the spring bar being pulled out. As such all Military Submariners have NATO straps as the more normal straps or bracelets cannot be fitted to the solid lugs. The hands were replaced with the aptly named Sword hands to enhance legibility with Tritium luminosity signified by the T in a circle on the dial.
