Meet the nylon VELCRO strap designed by NASA, made with its same exact original specifications. Same materials, same size and same stock number prints: the historical strap choice for your Speedmaster just like the astronauts who took it to the moon. 

The most commonly known version of the NASA strap, the one we usually see on archive photos, is the extra long black version worn over the space suit. Originally in olive green, this is the shorter version of the Velcro strap designed to be worn inside the spaceship.
