Watch Strap Elastic Marine Nationale NATO Parachute Nylon MOD Band 18mm 20mm 22mm Nylon Elastic French Marine Nationale Parachute Wrap Around Watch Strap with stainless steel holders to adjust the size. Suitable for between 6.5 inch wrist up to 8 inch wrists. Spring bar pins are included. This type of strap was originally handmade by the combat swimmers of the French Marine Nationale. The standard issue watches supplied to them came with the head only. Using their initiative they recovered the elastic straps from parachutes to sew them back on and adapt them to their watches. The parachute model is an innovative strap because itâÂÂs a loop so it adapts perfectly to the wrist. To wear it, you have to put your hand through it, adjust by pulling the end with the metal hook.
