A new range of NATO straps is introduced, with upgraded heavy-duty hardware. The new style is now available in black, green and grey in 18, 20 & 22mm.
Specification
Superior 1.2mm thick woven nylon ribbon with bead blasted solid stainless steel fittings. All joints are securely heat-welded and tested. All holes and strap ends are heat sealed. The MoD specification calls for heat welding: straps which are merely stitched do not meet the specification. All hardware is bead-blasted.
The holes in these straps are perfectly burnt and sealed with no melted nylon "scabs". There are 17 holes, starting 25mm from the end of the strap and spaced every 7mm. This means that the straps will fit all wrists from 5.5 to 10 inches.
Every strap has an overall length of 290mm, excluding buckle*. The specification calls for a 60mm spacing between the second and third rings (where the watch head fits) which is often inadequate to prevent the rings fouling the lugs on many of today's watches. The spacing on these straps has been increased to 80mm to accomodate larger watch heads.
*Please be aware that nylon can stretch and also shrink so all measurements are +/- 5mm for length and +/- 1mm for width.
